I was going to say the same thing your English is very easy to understand and I’m in the process of building my own generator box that also fits my 60 gallon husky air compressor. Brought home a truck load of lumber and plywood and I can walk into the building it’s only 3 ft deep but 6 ft tall and 8ft wide! My 10,000 btu air conditioner will sit above the generator and the air compressor will stand next to it. Great video glad it works for you this looks very well built! You care about your neighbors too that’s great, you must be a nice guy.
Great job ! Only thing I would of done different is put the exhaust fan all the way up to the ceiling as thats where the heat will go. Inlet vent low on one side, exhaust fan high on the other side. Looks beautiful !
You are right. This was an option i've been thinking about. Instead, i have chosen to put it near the motor where heat was produced. But you are absolutely right! Thx for sharing!
Very nice job. It sounds like the shed is very effective at reducing the noise to an acceptable level. I am running my Champion generator now due to a storm taking out power and wishing I had a similar sound shed for mine! I will check the materials for your build and decide if I want to build one.
Alain this is a low budget install and that is clearly what you wanted so fine. It is so easy to blow the budget building a shelter. I spent a whole lot of $$ on mine but will leave a couple of comments I hope you will find useful: In my experience the fan is too small. Ideally you would like a temperature rise of 10F but 20F is on the high side. For Que. outages in winter no problem but in summer it can matter. I ended up with a 16" fan rated at 3,000 cfm and the temp. inside my 5kw compartment did not rise more than 10F. That is outside 78F and inside 88F. On my first try with a 12" fan the temperature inside rose by 50F. Killing sound is expensive and time consuming and painstaking. Small openings in walls etc. can negate everything you do so you need to eliminate small openings. Sound likes to travel in straight lines so you can buy sheet metal exhaust hoods and line them with sound proofing material and install on the intake and fan exhaust openings. To attenuate sound think mass to provide a barrier and on top a softer material to absorb sound energy such as the mineral wool you applied. In my case I used MLV (multi layer vinyl against the walls held in place with insulation pins and on top of this a mineral wool similar to what you used. The mineral wool I bought had a facing on it so you were not exposed to the itchy fibers. Where there was exposed fibers I used a 3M adhesive spray and stuck plastic to the surface. You can spend a lot trying to make it quiet with disappointing results so be careful before opening your wallet. I invested in a propane conversion kit so I can run on gas or propane. It is set up for propane to avoid the storage issues and gumming of the carburetor. If you stick with gas, think about a fuel stabilizer to keep the gas from going bad. Another thing to consider is to perhaps install a bimetallic temperature shutoff switch. These come in different temp. settings and are cheap on Ebay and will shut off the generator if, for example, the fan fails and you are not around to watch it overheat. In my case I bought a normally open version and I connected it to the low oil level circuit on the generator and it triggers at 50C. I tested it with a hair dryer and it works. Hope some of this helps.
Real Thanks for taking the time to give me your comment Cayrick. For the fan, you are right. I notice it after few tests. Temperature was rising high and i was thinking about the shutoff switch. I will definitely look for one. You are also right about the opening on the shed for air intake and exhaust. These are the place where much part of the sound goes out. I will fix that by doing something similar as you wrote to direct the sound on ground. . For my place here in quebec, we rarely have outage on summer time. Most power outage occurs during winter time. The shed is surprisingly quiet for the price i invest. I put pyrok and fire wool in it. The firewool is more dense, so it absorb lot of noise. Now my main concern is about snow on ground. We can have as much as 1 meter of snow here. So i will have to clear the snow around the shed. Once again thank you very very much for giving me precious comments.
Alain I lived 20 years in Mtl. and worked for 6 months on a project in Ste. Foye so I know all about the snow. Now it is Panama and no snow but warm operation. Forgot to mention as well to think about a muffler as well. In my case the Honda Generator has a basic muffler so I welded a flange and connected flex pipe to the compartment exterior and then a short section of straight pipe and an auto muffler. This helped. As for the air deflectors you can buy these already made if you do a search on "exhaust deflectors". My biggest lesson in my project was learning to control the budget and I did not. One rule of thumb was The compartment and elect. hookup will run you twice the price of the generator and in my case it was 3 times. In this sense I respect you for your approach. Good luck.
@@cayrick Very good topic - not too many people consider this. This should be nr1, then noise... I have 2 exhaust fans mounted on the side of the motor(closest) and an intake fan placed across.... I tested 2hrs run in the summer 90deg-no shade.... It was just a little warm to the touch(the gas tank closest to the engine)
I am kind specialist on nema4 enclosures and other outdoor enclosures and would add that if you make a couple or air traps (so the air need to travel a little bit longer on the in and out ports not only would avoid water dust pollen intrussion but would decrease even more the dB. As a matter of fact plan to do the same this winter. Anyway very nice your project ..! Good ideas you get out of that.
@@AlainBoisclaircoaching so I have it installed and it was super easy. I sound insulated the shed the Gen is in and it’s nice. Thanx again for the tip. I highly recommend this product as do you.
Great shed build! I am about to make one, not so much for noise reduction, but as protection from bad weather. You have given me some good ideas. Merci!
The generator is there permanently. Those engine are made for outdoor use. The major challange is much with cold temperature. I didnt have to start my engine at real cold temperature yet
Generally the muffler isn't the noise maker, it is the machanics of the engine, but in this case you needed to vent it out and have it long enough to clear the structure
If you make the internal dimensions larger to accommodate some baffles for air in/outlets, and direct the exhaust out the side away from the house it’d make a world of difference.
Bouctouche! Tabouère, c'est un ptit bout from here! But give it a try! Very helpful. You must have cold weather like us around your place. Keep me inform!
@@AlainBoisclaircoaching I have been here for a little over two years. Moved from Ontario and find the weather here in the winter much milder than Qc or ON.
Nicely done. I am considering a similar enclosure for my 14Kw Generac. I did put a 30 Amp Dupelx outlet near the Genset that I can offer my neighbours should they complain, or not. I have a 50'#12 cable and outlet to get to their porch.
Rockwhool insolation is great. Some others gave me hint for improving it: Diverting the ventilation to the ground and add an exhaust pipe going up at 7 ft. Add a rubber mat for cow under the generator. I will try those
@@AlainBoisclaircoaching Hi Alain, how are you making the connection? I'm in Montreal and have a similar setup. I want to go through a proper transfer switch but haven't done it yet. Hydro Quebec is so reliable that I'm dragging my feet but you never know when the next ice storm will hit us like it did years ago.
@@MichaelAChang I bought a transfer switch kit At Home Depot. Check for reliance transfer switch. Easy to connect, you can even do it by yourself is you know electricity. (here's the link: tinyurl.com/2fywtyrh).
@@AlainBoisclaircoaching I put interlock switch - made it in the garaj. It disconnects the grid and powers all circuits. I have balanced all the breakers(fuses), now its using each 110V leg equally from the generator
Nice design and very practical. Having said that, I see the exhaust (both fume and air) is aimed at your house, which will tend to defeat some of the sound suppression. You could easily use a 90 degree elbow on the muffler, to re-direct the sound away. Also, might I suggest rubber matting beneath the generator?
Well, noise have a logarithmic attenuation. It mean that at each feet away from noise, the noise level is divide by two. 57db is the sound of a conversation between two human.
Wow best looking home made generator box , I seen so far, just need to do as you said put a board on a angle at the air intake vent, and it should reduce the noise level by 5-10 dbs. Quick question since you have it next to the house, do your feel the vibrations inside of the house when it's running?
If the fan fails the generator will overheat and cause a fire. Another TH-cam video had this issue. Their is an auto shut off you can add to the generator low oil kill switch that will shut the generator down if the temperature is too high in the box. Also I would elevate your box so the wood does not rot or slow the rotting down where the wood is in contact with dirt. Nicely done though overall.
Your are damn right. I've been working in origin and cause of fire for 20 years so i know what you mean for sure. I've check some killswitch on amazon. Didn't found one yet but i will fix that. For now, i had used it only on winter days, and leave a small opening in front. ;)
Nice build Alain. I am working on my shed right now and overheating is a concern. I originally installed an 960 cam fan but the temperature keep raising inside the shed. I replaced the fan with a 2000 cfm variable speed fan. Also, I installed inside the shed a temperature probe so I can monitor the temperature from inside my home. I can set up an alarm if it gets too hot.
Fantastic work, and excellent video. Thank you so much for taking the time to share your expertise and experience. I'd like to build something similar, though I don't have as strong a need for insulation as the nearest houses aren't very close. My main objective is to protect the generator from the elements, whether it's in use or not. As a result, I may not need the complete wall coverage that you have and can plan to leave parts of the wall open during operation. One specific question that I had was the material to use as the floor/base. It looks as though you are using regular plywood as opposed to fireproof cement board.. is that correct? I guess there is not very much heat coming off the bottom of the generator?
Hello Jaslyman.Thks for the good words! Yes you are right, i used plywood for the floor and no, there is no heat at the buttom due to the exhaust fan. BUT, if i had to do it again, i would leave the generator on concrete plates or make a small slab. Another thing i would certainly make different is build the box a little bit higher with only front doors opening. Why? It is snowing in my country and i have to clear the snow off the cover each time i want to open it. But this is not a big issue. Ciment board is important for heat protection. Good luck and give me news if you make it!
With a wooden door around the blower outlet that is open from below (so that the warm air can still escape) it becomes even quieter. something similar applies to the exhaust and the air inlet of the cabinet
I bet using some stucco inside that box you could dampen the sound even more. Im looking at ideas for building one myself so I'm looking through TH-cam to see what does and doesn't work for people. I'm planning to do pretty much what you've done there, but I plan to stucco the inside of the box and build a baffle around the intake. If the stucco idea interest you, you don't need a stucco sprayer or any special tools, you can get good ridged textures easily for the cost of a bag of stucco mix and time.. Applied thinly with a trowel or a gloved hand, and textured using a piece of plywood with a plastic bag on it, pressed into the stucco and pulled out and down to created downward pocketed ridges, the cement will stick to the bag, creating big ridges which is what you'd want. For a little more dampening, I wonder if aircrete-ifying the stucco first might help even more by creating more tiny pockets to capture the sound. I made an aircrete foam generator so that's probably what I'll do, dependent on a test to see how stable it is in textured form. If you ever been in an empty room with smooth walls prior to texturing, then after texture, you notice a pretty substantial difference in sound, as the bigger the texture, the more damped the sound, less echo, etc. The main idea is to add an exaggerated texture pattern to the walls. It won't look pretty and you won't want to knock it down at all if possible. The two main downside to this are 1 looks, and 2. It'll create a lot of tiny places for spiders a make little nests and it'll capture dust that you can't clean except to blow air at it. The upside to spider's is their webs might add some extra (free) dampening 😁
@@AlainBoisclaircoaching interesting, pyrok is new to me, had to look that up. I assume from your comment that it's not very heat tolerant. If you mentioned it in the video I missed it I guess or assumed you were referring to the durock Hardi board. I'll be tackling this next month, and I'm basically just going to keep at it until I've tried everything I can think of to get it at least to where it's barely noticeable. In case you're interested in what I've got in mind, I'll list it real quick, as it's changed a bit since I commented. 1. Intake muffler (maybe not necessary, I need to test with decibel meter that I haven't purchased yet but I imagine it'll account for some noise) 2. Double walled on two sides, (the sides with the air intake and the exhaust). With the air channeled through a horizontal W or V shaped baffle built-in to the double wall with rock board Rockwool. 3. From outside in, the layers would be: plytanium siding, rockwool batting, Rockwool panel, with a standoff on the sides for the double wall with in built baffle. I may end up putting Hardi board between the batting and the panels, I'm not sure yet. I'll be building it without hardi at first, then testing with some thermistors that I plan to have in the back wall and the ceiling. I really want to avoid having any hard surfaces that can resonate, if at all possible. 4. The door will be built the same as the walls, with a nice rockwool gasket all the way around. 5. The exhaust, I'm still trying to figure out, but what I'm thinking is this. It will be increased to 2" pipe right out of the engine and 90° up to a homemade muffler inside the shed, pipe increased to 3", extending upward to the level of the shed roof to hopefully direct sound upwards.. I'm not sure about the exit, whether or not there should be a weather cap or a flap or what. I'm also not sure directing the sound up is the answer. I'm toying with the idea of the frankenmuffler, if you haven't seen it, it's a 55gal metal trashcan a guy made into a pretty nice muffler. Except instead of having it above ground, have it in a rock wool box or maybe even below ground or something. I'm really not sure, as that may be bordering on overkill. Something to think about, anyways, and if I have time, obsess about.. lol. The idea of running the generator and everyone around me hearing it causes me stress, so I'd like to avoid that stress if at all possible..
Hello Alain: How did you get the power cord into your shed for hook up to the generator? I have seen other videos with many ways to do that. Really like your shed and plan to build mine very fimilar. I may do some of the suggestions listed here that you like as well.
Hello Biker Boy. Gooooood question! Lol. For now, i just leave the door a little bit open enough to get the space for the power cord run thru it. But i figured out i could use an outlet on the shed that could be connected permanently inside to the generator. So i would just need to connect the power cord outside directly to it.
@@AlainBoisclaircoaching Building my shed now, going well. Using a lot of your ideas to do mine. I think I will use a small trap door/opening for my power cord and gas hoses. Thanks for help.
Build and attach a box to your enclosure, over your intake and discharge openings, with the bottom open, and insulate that box @@AlainBoisclaircoaching
they should be able to make them less noisy straight from the factory ? they make zero attempt at noise reduction ? hondas are good but still could be better.
As you kind Sir; many generators' owners have tried to mute that horrid noise. Sadly, EVEN what you have done; there is still too much noise. But...I found one TH-cam, where a man, that really fought the noise and took it from 90 DB to 40 DB. And he proved it. It is incredible. If any one of you would like to see it; it's named "5x quieter". I believe it's the best way I have seen to date; to get that horrid noise down that almost mutes it totally. Pay much attention to the exhaust pipe and how he took the noise high in the air. For what it's worth. P.S. The fire mute you used, does not mute noise. It only stops fire. The "Rock-Wool" you used will do a good job of muting noise. Sadly, the inlet and outlet openings; almost stops all the muting. The video above WILL also stop that awesomely.
Thank you for your comment Pat. Unless you have done it, sorry to say that, but my setup is indeed reducing the major part the noise. This is right. Many many factors influence those results. The size and brand of the generator, thickness of wood, type of exhaust, the orientation of the shed, the position of air entry and exhaust, and Rookwool. Pyrok is for fire and do contribute to absorb a part of the noise together like any other materials would do with different type of results. For the exhaust and air intake you are right. I have to direct the noise to the ground. The results are already surprising and will be much quieter when i will add those cover. For measuring noise, there is a method for doing it. It depend of the distance you measure it. Noise propagation is logarithmic. So if you measure at on feet of the generator vs 10 ft, you will surely have different reading. So you have to do multiple reading to get accurate measurement.
@@AlainBoisclaircoaching This Guy was Right about the Opening of intake and Outtake. Must Combat that Opening To Really Reduce Noise Level. ...... I did managed To Bring it DOWN to 56 db with My Muffler Silencer made from Ply-wood Only. If want proof just let me know 😅
@@AlainBoisclaircoaching I have something similar, it works, don't worry about the haters - 50db is perfect silence.... If you quiet down most of it, it's ok - it works. What I like on yours, its done right - safety/cooling first. I've seen plenty running hot and bragging about sound
Merci Alain. Beau travail et informations utiles. T'as pas peur que ton ouverture pour l'entrée d'air soit bloquée par la neige? I am looking for a silencer that will work a Westinghouse 12000DF generator. I have read that using the wrong type of muffler silencer unit could damage your generator engine over time. So not sue the unit you got for your Firman would be suitable for my generator. Input anyone?
@@danv71678 My comment was regarding when the generator is not running. He stated he would have to run a line out to the shed, in order to run a fan, to pull the hot air out during the day…when the generator is not operational.
It depends of the outside temperature. I had never made the measurment but I usualy run it in winter and here in Quebec it is very cold outside (-30?) sometimes. I test it in summer and with the fan the temperature is never too high.
What is the sound/noise dampening insulation, name and where did you order it from. I like that you built the shed yourself. My main concern is fire proofing the interior and putting noise/sound dampening insulation inside. I have all the exhaust and heat issues figure out. My DIY shed is 3'X5'X30". Good job on your shed.
i've used Rockwool Safe'n'Sound and got it on Home Depot. I covered my insolation with cement board like the one you put behing fireplace in home construction
Is the generator permanently stored in the shed or do you store it somewhere else when not in use ? If you store it in the shed, how do you control damages to the generator from moisture such as humidity, etc, to the generator over time ?
That's Cool that you can do that. I've been building mine for the past week. We have been getting rain every 2-3 days. So that puts a wrench in getting it done.
This is a good question. It depend of the size of your tank. But for me, i would use a gaz line from the tank to the shed. I would leave the tank away from about 10 feet. Just to make sure.

I tried to order this item for my Firman generator, and it says I need a Canada broker, which adds another $759 in shipping cost to get it delivered to Nova Scotia. Is there a way around this?
why does no one build walls that are non-parallel? Part of soundproofing is reflecting sound waves. Having walls that are non-parallel, or that are baffled adds a lot of free soundproofing.
I assume you are referring to a SPL / dB meter app? I was about to suggest that as well. They may not be as accurate as a properly calibrated standalone meter, but I would say it is very close. Close enough for TH-cam!
Nice Job, thanks for sharing! Anything you would do differently after some time of using this? Planning a similar project so I will be saving and rewatching your video. TH-cam is so nice for sharing stuff like this amoung DIY'ers! :)
All the heating componants, like fireplace or generator have a clearance to respect. Some material can help reduce that clearance. Like concrete panel. For each problem, there is a solution ;)
Thanks for the reply. I am making my shed now. I am finishing up the outside first and then I will focus on the inside: installing exhaust fan, air vent, insulation.
Shed is completly independant from the other shed and have a fireproof panel inside. Of course each spill could set fire on a building anyway. The risk is very very small in that case. But yes, there is still a risk if, for exemple, the pipe feeding the motor break. Never saw that and been working for a forensic cie on cause and origin of fire for 20 years. ;)
Had a couple chewed exposed wires on a Generac where it goes to the oil pressure sensor. They cut the insulation every inch and broke one wire in half. An easy fix was soldering it together, the using heat shrink tubing, I recovered the 2 damaged wires. Better than new now. I find Harbor freight has a nice package of 5 different sizes in white boxes, and the tubing is long like 3 feet.
@@AlainBoisclaircoaching yes, but whatever come in goes out, if you bring in cool air it will push out the hot and the fan will not overheat and will last a lots longer.
get a car / golf cart battery and a 12v to DC convertor (300 watts) to power the exhaust fan ... a small battery charger can be used during the check-up schedule time and charge the batter this way .... a small timer can be used to shut off the charger after possible 10-15 min of use ...
What would be the purpose of running the fan with a battery if i can connect it directly on the generator? Also, fan is running on AC not DC. I would also need an inverter...
@@AlainBoisclaircoaching you did it right my friend.... That's what you should be doing - direct in gen; no need to run it when gen is off. The amp is low on the fan, no consumption. And it will always work - batteries always die
Your English is just fine. No need to apologize
Thx Fred!
I was going to say the same thing your English is very easy to understand and I’m in the process of building my own generator box that also fits my 60 gallon husky air compressor. Brought home a truck load of lumber and plywood and I can walk into the building it’s only 3 ft deep but 6 ft tall and 8ft wide!

Thank you spkay31. It is effective and it will be more when i will add wood case where my air input and exhaust are.
Another youtuber built baffle boxes at the intake and exhaust ports. It helped to reduce noise even more.
Thank you, it is in my plan to do that!
Alain this is a low budget install and that is clearly what you wanted so fine. It is so easy to blow the budget building a shelter. I spent a whole lot of $$ on mine but will leave a couple of comments I hope you will find useful:
In my experience the fan is too small. Ideally you would like a temperature rise of 10F but 20F is on the high side. For Que. outages in winter no problem but in summer it can matter. I ended up with a 16" fan rated at 3,000 cfm and the temp. inside my 5kw compartment did not rise more than 10F. That is outside 78F and inside 88F. On my first try with a 12" fan the temperature inside rose by 50F.
Killing sound is expensive and time consuming and painstaking. Small openings in walls etc. can negate everything you do so you need to eliminate small openings. Sound likes to travel in straight lines so you can buy sheet metal exhaust hoods and line them with sound proofing material and install on the intake and fan exhaust openings.
To attenuate sound think mass to provide a barrier and on top a softer material to absorb sound energy such as the mineral wool you applied. In my case I used MLV (multi layer vinyl against the walls held in place with insulation pins and on top of this a mineral wool similar to what you used. The mineral wool I bought had a facing on it so you were not exposed to the itchy fibers. Where there was exposed fibers I used a 3M adhesive spray and stuck plastic to the surface. You can spend a lot trying to make it quiet with disappointing results so be careful before opening your wallet.
I invested in a propane conversion kit so I can run on gas or propane. It is set up for propane to avoid the storage issues and gumming of the carburetor. If you stick with gas, think about a fuel stabilizer to keep the gas from going bad.
Another thing to consider is to perhaps install a bimetallic temperature shutoff switch. These come in different temp. settings and are cheap on Ebay and will shut off the generator if, for example, the fan fails and you are not around to watch it overheat. In my case I bought a normally open version and I connected it to the low oil level circuit on the generator and it triggers at 50C. I tested it with a hair dryer and it works.
Hope some of this helps.
Real Thanks for taking the time to give me your comment Cayrick. For the fan, you are right. I notice it after few tests. Temperature was rising high and i was thinking about the shutoff switch. I will definitely look for one. You are also right about the opening on the shed for air intake and exhaust. These are the place where much part of the sound goes out. I will fix that by doing something similar as you wrote to direct the sound on ground. .
For my place here in quebec, we rarely have outage on summer time. Most power outage occurs during winter time. The shed is surprisingly quiet for the price i invest. I put pyrok and fire wool in it. The firewool is more dense, so it absorb lot of noise. Now my main concern is about snow on ground. We can have as much as 1 meter of snow here. So i will have to clear the snow around the shed.
Once again thank you very very much for giving me precious comments.
Alain I lived 20 years in Mtl. and worked for 6 months on a project in Ste. Foye so I know all about the snow. Now it is Panama and no snow but warm operation. Forgot to mention as well to think about a muffler as well. In my case the Honda Generator has a basic muffler so I welded a flange and connected flex pipe to the compartment exterior and then a short section of straight pipe and an auto muffler. This helped.
As for the air deflectors you can buy these already made if you do a search on "exhaust deflectors".
My biggest lesson in my project was learning to control the budget and I did not. One rule of thumb was The compartment and elect. hookup will run you twice the price of the generator and in my case it was 3 times. In this sense I respect you for your approach. Good luck.
Do you have the link for the fan you installed?

@@cayrick Very good topic - not too many people consider this. This should be nr1, then noise... I have 2 exhaust fans mounted on the side of the motor(closest) and an intake fan placed across.... I tested 2hrs run in the summer 90deg-no shade.... It was just a little warm to the touch(the gas tank closest to the engine)
I am kind specialist on nema4 enclosures and other outdoor enclosures and would add that if you make a couple or air traps (so the air need to travel a little bit longer on the in and out ports not only would avoid water dust pollen intrussion but would decrease even more the dB. As a matter of fact plan to do the same this winter. Anyway very nice your project ..! Good ideas you get out of that.
Great advise, thank you! Keep me in touch! I am curious!
Huge difference in noise volume. Great build!
Sir you gave me the solution I couldn’t find. The muffler is a bit pricey but exactly what I was looking. Thank you. Nice video.
great!
@@AlainBoisclaircoaching so I have it installed and it was super easy. I sound insulated the shed the Gen is in and it’s nice. Thanx again for the tip. I highly recommend this product as do you.
Wow what a difference with roof and doors closed very quiet!!
Great shed build! I am about to make one, not so much for noise reduction, but as protection from bad weather. You have given me some good ideas. Merci!
The generator is there permanently. Those engine are made for outdoor use. The major challange is much with cold temperature. I didnt have to start my engine at real cold temperature yet
Awesome job. I just bought a Firman tri fuel. MAN is it noisy. Thanks so much for this idea
Yes they are all very noisy. Of course, if you have the budget you can think buying a Honda generator but... $$$ ;)
Never apologize for being bilingual
Oh I like the way you design that that is really nice and your English is fine
Thx Bill!
Generally the muffler isn't the noise maker, it is the machanics of the engine, but in this case you needed to vent it out and have it long enough to clear the structure
If you make the internal dimensions larger to accommodate some baffles for air in/outlets, and direct the exhaust out the side away from the house it’d make a world of difference.
Merci Alain! I will be building mine soon in Bouctouche NB! You have given me good idea
Bouctouche! Tabouère, c'est un ptit bout from here! But give it a try! Very helpful. You must have cold weather like us around your place. Keep me inform!
@@AlainBoisclaircoaching I have been here for a little over two years. Moved from Ontario and find the weather here in the winter much milder than Qc or ON.
Nicely done. I am considering a similar enclosure for my 14Kw Generac. I did put a 30 Amp Dupelx outlet near the Genset that I can offer my neighbours should they complain, or not. I have a 50'#12 cable and outlet to get to their porch.
Very nice build, thank you for sharing. I am preparing to build my own and you have given me some great ideas.
Rockwhool insolation is great. Some others gave me hint for improving it: Diverting the ventilation to the ground and add an exhaust pipe going up at 7 ft. Add a rubber mat for cow under the generator. I will try those
Nice build. Good job / much quieter!
Excellently done! You covered all details splendidly! Thank you for wonderful idea and sharing!!! 😃👍👏👏
Thx jo!
Very nice; you thought of everything. It looks like you're still working on getting the output to the house.
The only thing i have to do, is connecting it when there is a power outage. Thx Michael
@@AlainBoisclaircoaching Hi Alain, how are you making the connection? I'm in Montreal and have a similar setup. I want to go through a proper transfer switch but haven't done it yet. Hydro Quebec is so reliable that I'm dragging my feet but you never know when the next ice storm will hit us like it did years ago.
@@MichaelAChang I bought a transfer switch kit At Home Depot. Check for reliance transfer switch. Easy to connect, you can even do it by yourself is you know electricity. (here's the link: tinyurl.com/2fywtyrh).
@@AlainBoisclaircoaching I put interlock switch - made it in the garaj. It disconnects the grid and powers all circuits. I have balanced all the breakers(fuses), now its using each 110V leg equally from the generator
Nice design and very practical.
Having said that, I see the exhaust (both fume and air) is aimed at your house, which will tend to defeat some of the sound suppression. You could easily use a 90 degree elbow on the muffler, to re-direct the sound away. Also, might I suggest rubber matting beneath the generator?
It will be a great idea. I’ved already figure to put cow rubber under it
Your English is great! Thanks for the information. Very helpful
Merci, Alain.
Whoever wants to Sleep Good at night with Generator enclosure that gives 57 db level at 15 ft..... Really good 😂
Well, noise have a logarithmic attenuation. It mean that at each feet away from noise, the noise level is divide by two. 57db is the sound of a conversation between two human.
@@AlainBoisclaircoachingI'm talking in Real numbers here but not in Equation or theory 😅
Wow best looking home made generator box , I seen so far, just need to do as you said put a board on a angle at the air intake vent, and it should reduce the noise level by 5-10 dbs. Quick question since you have it next to the house, do your feel the vibrations inside of the house when it's running?
No vibration at all. The shed is placed at about 25 feet from the house and well isolated!
If the fan fails the generator will overheat and cause a fire. Another TH-cam video had this issue. Their is an auto shut off you can add to the generator low oil kill switch that will shut the generator down if the temperature is too high in the box.
Also I would elevate your box so the wood does not rot or slow the rotting down where the wood is in contact with dirt. Nicely done though overall.
Your are damn right. I've been working in origin and cause of fire for 20 years so i know what you mean for sure. I've check some killswitch on amazon. Didn't found one yet but i will fix that. For now, i had used it only on winter days, and leave a small opening in front. ;)
Nice build Alain. I am working on my shed right now and overheating is a concern. I originally installed an 960 cam fan but the temperature keep raising inside the shed. I replaced the fan with a 2000 cfm variable speed fan. Also, I installed inside the shed a temperature probe so I can monitor the temperature from inside my home. I can set up an alarm if it gets too hot.
👍 Nice job. A simple wood baffle over the intake and exhaust and it will be perfect.
You are right Edward.
Thank you,
Your English is OK😊
Fantastic work, and excellent video. Thank you so much for taking the time to share your expertise and experience. I'd like to build something similar, though I don't have as strong a need for insulation as the nearest houses aren't very close. My main objective is to protect the generator from the elements, whether it's in use or not. As a result, I may not need the complete wall coverage that you have and can plan to leave parts of the wall open during operation. One specific question that I had was the material to use as the floor/base. It looks as though you are using regular plywood as opposed to fireproof cement board.. is that correct? I guess there is not very much heat coming off the bottom of the generator?
Hello Jaslyman.Thks for the good words! Yes you are right, i used plywood for the floor and no, there is no heat at the buttom due to the exhaust fan. BUT, if i had to do it again, i would leave the generator on concrete plates or make a small slab. Another thing i would certainly make different is build the box a little bit higher with only front doors opening. Why? It is snowing in my country and i have to clear the snow off the cover each time i want to open it. But this is not a big issue. Ciment board is important for heat protection. Good luck and give me news if you make it!
With a wooden door around the blower outlet that is open from below (so that the warm air can still escape) it becomes even quieter. something similar applies to the exhaust and the air inlet of the cabinet
@@henkholdingastate Thx. I will do that!
I bet using some stucco inside that box you could dampen the sound even more. Im looking at ideas for building one myself so I'm looking through TH-cam to see what does and doesn't work for people. I'm planning to do pretty much what you've done there, but I plan to stucco the inside of the box and build a baffle around the intake.
If the stucco idea interest you, you don't need a stucco sprayer or any special tools, you can get good ridged textures easily for the cost of a bag of stucco mix and time.. Applied thinly with a trowel or a gloved hand, and textured using a piece of plywood with a plastic bag on it, pressed into the stucco and pulled out and down to created downward pocketed ridges, the cement will stick to the bag, creating big ridges which is what you'd want.
For a little more dampening, I wonder if aircrete-ifying the stucco first might help even more by creating more tiny pockets to capture the sound. I made an aircrete foam generator so that's probably what I'll do, dependent on a test to see how stable it is in textured form.
If you ever been in an empty room with smooth walls prior to texturing, then after texture, you notice a pretty substantial difference in sound, as the bigger the texture, the more damped the sound, less echo, etc. The main idea is to add an exaggerated texture pattern to the walls. It won't look pretty and you won't want to knock it down at all if possible.
The two main downside to this are 1 looks, and 2. It'll create a lot of tiny places for spiders a make little nests and it'll capture dust that you can't clean except to blow air at it. The upside to spider's is their webs might add some extra (free) dampening 😁
I’ve put pyrok inside to damper the noise. I also have to consider the heat factor. If you find a better solution let me know! Thanks for sharing!
@@AlainBoisclaircoaching interesting, pyrok is new to me, had to look that up. I assume from your comment that it's not very heat tolerant. If you mentioned it in the video I missed it I guess or assumed you were referring to the durock Hardi board.
I'll be tackling this next month, and I'm basically just going to keep at it until I've tried everything I can think of to get it at least to where it's barely noticeable.
In case you're interested in what I've got in mind, I'll list it real quick, as it's changed a bit since I commented.
1. Intake muffler (maybe not necessary, I need to test with decibel meter that I haven't purchased yet but I imagine it'll account for some noise)
2. Double walled on two sides, (the sides with the air intake and the exhaust). With the air channeled through a horizontal W or V shaped baffle built-in to the double wall with rock board Rockwool.
3. From outside in, the layers would be: plytanium siding, rockwool batting, Rockwool panel, with a standoff on the sides for the double wall with in built baffle.
I may end up putting Hardi board between the batting and the panels, I'm not sure yet. I'll be building it without hardi at first, then testing with some thermistors that I plan to have in the back wall and the ceiling.
I really want to avoid having any hard surfaces that can resonate, if at all possible.
4. The door will be built the same as the walls, with a nice rockwool gasket all the way around.
5. The exhaust, I'm still trying to figure out, but what I'm thinking is this. It will be increased to 2" pipe right out of the engine and 90° up to a homemade muffler inside the shed, pipe increased to 3", extending upward to the level of the shed roof to hopefully direct sound upwards.. I'm not sure about the exit, whether or not there should be a weather cap or a flap or what.
I'm also not sure directing the sound up is the answer. I'm toying with the idea of the frankenmuffler, if you haven't seen it, it's a 55gal metal trashcan a guy made into a pretty nice muffler. Except instead of having it above ground, have it in a rock wool box or maybe even below ground or something. I'm really not sure, as that may be bordering on overkill. Something to think about, anyways, and if I have time, obsess about.. lol.
The idea of running the generator and everyone around me hearing it causes me stress, so I'd like to avoid that stress if at all possible..
Outstanding job sir!
Thanks for sharing. Lot of great info and ideas.
Great! Thank you Leigh!
Hello Alain: How did you get the power cord into your shed for hook up to the generator?
I have seen other videos with many ways to do that.
Really like your shed and plan to build mine very fimilar. I may do some of the suggestions listed here that you like as well.
Hello Biker Boy. Gooooood question! Lol. For now, i just leave the door a little bit open enough to get the space for the power cord run thru it. But i figured out i could use an outlet on the shed that could be connected permanently inside to the generator. So i would just need to connect the power cord outside directly to it.
OR, i could make a little "u" trap on top of the door to put the power cord on it so i could close the cover.
@@AlainBoisclaircoaching Building my shed now, going well. Using a lot of your ideas to do mine. I think I will use a small trap door/opening for my power cord and gas hoses. Thanks for help.
@@bikerboy8666 Great idea! I tought of that too
If you built a very simple open bottomed cover for over the intake and fan you'd get even better noise reduction.
Can you explain? I am not sure i understand.
Build and attach a box to your enclosure, over your intake and discharge openings, with the bottom open, and insulate that box
@@AlainBoisclaircoaching
Great Build Amigo
Bonjour Alain I would love to link up with you I just got a genarater and I have to make a shed
Sure, what would you like to know christian?
they should be able to make them less noisy straight from the factory ? they make zero attempt at noise reduction ? hondas are good but still could be better.
As you kind Sir; many generators' owners have tried to mute that horrid noise. Sadly, EVEN what you have done; there is still too much noise. But...I found one TH-cam, where a man, that really fought the noise and took it from 90 DB to 40 DB. And he proved it. It is incredible.
If any one of you would like to see it; it's named "5x quieter". I believe it's the best way I have seen to date; to get that horrid noise down that almost mutes it totally. Pay much attention to the exhaust pipe and how he took the noise high in the air.
For what it's worth.
P.S. The fire mute you used, does not mute noise. It only stops fire. The "Rock-Wool" you used will do a good job of muting noise. Sadly, the inlet and outlet openings; almost stops all the muting. The video above WILL also stop that awesomely.
Thank you for your comment Pat. Unless you have done it, sorry to say that, but my setup is indeed reducing the major part the noise. This is right. Many many factors influence those results. The size and brand of the generator, thickness of wood, type of exhaust, the orientation of the shed, the position of air entry and exhaust, and Rookwool. Pyrok is for fire and do contribute to absorb a part of the noise together like any other materials would do with different type of results.
For the exhaust and air intake you are right. I have to direct the noise to the ground. The results are already surprising and will be much quieter when i will add those cover.
For measuring noise, there is a method for doing it. It depend of the distance you measure it. Noise propagation is logarithmic. So if you measure at on feet of the generator vs 10 ft, you will surely have different reading. So you have to do multiple reading to get accurate measurement.
I've ordered a db noise meter and i will get back to you with my results soon
@@AlainBoisclaircoaching This Guy was Right about the Opening of intake and Outtake. Must Combat that Opening To Really Reduce Noise Level.
...... I did managed To Bring it DOWN to 56 db with My Muffler Silencer made from Ply-wood Only. If want proof just let me know 😅
@@AlainBoisclaircoaching I have something similar, it works, don't worry about the haters - 50db is perfect silence.... If you quiet down most of it, it's ok - it works. What I like on yours, its done right - safety/cooling first. I've seen plenty running hot and bragging about sound
Merci Alain. Beau travail et informations utiles. T'as pas peur que ton ouverture pour l'entrée d'air soit bloquée par la neige?
I am looking for a silencer that will work a Westinghouse 12000DF generator. I have read that using the wrong type of muffler silencer unit could damage your generator engine over time. So not sue the unit you got for your Firman would be suitable for my generator. Input anyone?
Je déblaye avant de la partir. ;)
Très beau travail !!!! 😀
merci!
Awesome job! Would a solar fan be an option, for when the generator isn’t running?
that would work when its sunny but if you need the exhaust fan to run at night might as well just use the generator to power the fan
@@danv71678 My comment was regarding when the generator is not running. He stated he would have to run a line out to the shed, in order to run a fan, to pull the hot air out during the day…when the generator is not operational.
In fact there is no need to run the fan when the generator is not working.
I think there is an app for your phone to measure decibel sound levels?
There is a method to accuratly measure db attenuation and it requires a real dbmeter. But i’ll check this out. Thx
Nice job.
Thanks for sharing...
Plusieurs bonnes idées, je vais m’en inspirer!
Go for it! Je suis bien content de mon montage. Et je l'ai déjà utilisé a plusieurs reprises.
What is the peak temperature inside the shed when it’s running
It depends of the outside temperature. I had never made the measurment but I usualy run it in winter and here in Quebec it is very cold outside (-30?) sometimes. I test it in summer and with the fan the temperature is never too high.
What is the sound/noise dampening insulation, name and where did you order it from. I like that you built the shed yourself. My main concern is fire proofing the interior and putting noise/sound dampening insulation inside. I have all the exhaust and heat issues figure out. My DIY shed is 3'X5'X30". Good job on your shed.
i've used Rockwool Safe'n'Sound and got it on Home Depot. I covered my insolation with cement board like the one you put behing fireplace in home construction
Is the generator permanently stored in the shed or do you store it somewhere else when not in use ? If you store it in the shed, how do you control damages to the generator from moisture such as humidity, etc, to the generator over time ?
Read my answer above! Thx for commenting
Did you follow any plans or did you make it on the fly? I'm gonna try to make something similar.
I did it on the fly based on the generator i have
That's Cool that you can do that. I've been building mine for the past week. We have been getting rain every 2-3 days. So that puts a wrench in getting it done.
I would be using propane..but how you connected to generator?
This is a good question. It depend of the size of your tank. But for me, i would use a gaz line from the tank to the shed. I would leave the tank away from about 10 feet. Just to make sure.
Nice work Brother 🙏
Do you have any pictures as your were building the frame, roof, roof hinge?
No picture, unfortunatly
How was the muffler attached to the generator? Good video. Your English is just fine!

Hi Sidney, what kind of generator do you have? Here's a link: www.zombiebox.com/shop/honda-firman-exhaust-extension-kit
I tried to order this item for my Firman generator, and it says I need a Canada broker, which adds another $759 in shipping cost to get it delivered to Nova Scotia. Is there a way around this?
Nice job my friend. 👍
Thx my friend!
why does no one build walls that are non-parallel? Part of soundproofing is reflecting sound waves. Having walls that are non-parallel, or that are baffled adds a lot of free soundproofing.
Nice idea ! I am not a specialist in soundproofing. I would love to see such a shed!
Do it and become the generator ⭐️ on TH-cam. I have heard of this but nobody has yet.
Because rectangle boxes are intuitive and what people are used to. That's the simple answer tbh.
There are many free and simple sound measuring apps available for mobile phones.
I got myself a meter on amazon ;)
Very nice cover
I have one on my phone. Works great.
I assume you are referring to a SPL / dB meter app? I was about to suggest that as well. They may not be as accurate as a properly calibrated standalone meter, but I would say it is very close. Close enough for TH-cam!
Nice Job, thanks for sharing! Anything you would do differently after some time of using this? Planning a similar project so I will be saving and rewatching your video. TH-cam is so nice for sharing stuff like this amoung DIY'ers! :)
I will put noise deflector into the air inlet et outlet, directing noise to the ground.
Bonne idée et ingénieux.
The only problem with this is that the Firman manual says 5 feet clearance all the way around for safety.
All the heating componants, like fireplace or generator have a clearance to respect. Some material can help reduce that clearance. Like concrete panel. For each problem, there is a solution ;)
That 5 foot clearance would be without active ventilation. Crossflow power ventilation totally changes the space concerns.
Did you put the insulation around the exhaust on the inside? Or no?
The exhaust is isolated and i left an air gap around the exhaust pipe (1/2" about)
Thanks for the reply. I am making my shed now. I am finishing up the outside first and then I will focus on the inside: installing exhaust fan, air vent, insulation.
can you send me a closeup picture of the inside of the shed near the exhaust? Just trying to get some ideas.

Shed looks nice but shouldn't be attached to building. A gas leak and it could all go up flames!
Shed is completly independant from the other shed and have a fireproof panel inside. Of course each spill could set fire on a building anyway. The risk is very very small in that case. But yes, there is still a risk if, for exemple, the pipe feeding the motor break. Never saw that and been working for a forensic cie on cause and origin of fire for 20 years. ;)
Good job!
Very nice work. Are you concerned with rodents getting in your generatorand causing damage?
It’s all sealed 🙂
Had a couple chewed exposed wires on a Generac where it goes to the oil pressure sensor. They cut the insulation every inch and broke one wire in half. An easy fix was soldering it together, the using heat shrink tubing, I recovered the 2 damaged wires. Better than new now. I find Harbor freight has a nice package of 5 different sizes in white boxes, and the tubing is long like 3 feet.
I may add a few dryer sheets in the area. Rodents don’t like the smell.
Maybe add a solar battery tender?
I had the idea but did not made it yet 🙂
@@AlainBoisclaircoaching they are as low as $25 on Amazon.
Is your exhaust have a silencer on it?? that black end?
It’s a muffler to silence the noise. Looks like it’s for a motorcycle.

look at the link below. But make sure you find one specific for your generator
The fan should be on the intake of the shed to keep the fan cool
Hrmmm the purpose of the fan is actually to get the heat out..
@@AlainBoisclaircoaching yes, but whatever come in goes out, if you bring in cool air it will push out the hot and the fan will not overheat and will last a lots longer.
Belle job
Merci!
English its better than mine.
thx!
get a car / golf cart battery and a 12v to DC convertor (300 watts) to power the exhaust fan ... a small battery charger can be used during the check-up schedule time and charge the batter this way .... a small timer can be used to shut off the charger after possible 10-15 min of use ...
What would be the purpose of running the fan with a battery if i can connect it directly on the generator? Also, fan is running on AC not DC. I would also need an inverter...
@@AlainBoisclaircoaching you did it right my friend.... That's what you should be doing - direct in gen; no need to run it when gen is off. The amp is low on the fan, no consumption. And it will always work - batteries always die
