I have watched your video many times. My boyfriend and I just air conditioned the garage and decided we needed to insulate our garage doors. We used your plan and adapted it to our garage doors. It turned out very nice and has made a major difference. Thank you so much for your inspiration and your instruction.
I appreciate your unique approach to this Fred. The air gaps have to help isolate the heat quite a bit. Your attention to detail is amazing, most folks would skip the alcohol wiping but that will make the tape stick 5x to 10x longer than without that step. You are the type of guy anyone with any house pride would want to hire.
Doesn’t sound like it. My garage door is 1.5 inches from the lip to the front of the garage door. If he did a cell he’s have to account for probably another half inch
@@yevenstee I think I was able to get R-10 in there (2" thick pink Styrofoam board). I did have to lap-joint the edges in some spots because of the thickness of the garage door frame.
Wow. I've looked at over a dozen videos on this topic and have not seen anything like this. Amazing. Very thoughtful design. Great editing and script. This changes my idea about how to do my garage door.
Thanks for the kind remarks. This project wasn’t supposed to be a video, it was just a project that needed done. Filming inside my 100° garage was a challenge. In the end I am glad I recorded it and that I am able to share this project/concept with the world.
Metallic tape trick I recently learned: wet a tiny corner of the paper side. Use a thumb-nail to scratch off the wet paper. Now you can easily peel back the metallic tape and apply!!
I just used Reflectix to insulate the interior of my cargo van for my camping trips. It made a tremendous difference for hot or cold! I used the leftover material to make an insulation panel to shield my AC condensor in the patio from the summer sun. The area above the panel facing the sun was 140 degrees and the area below the panel was 95 degrees! The concrete floor of the patio where it is installed was 120 degrees!
I watched quite a few videos about insulating garage doors and compared temp differences. Your method made the greatest difference in degrees. We live in the Atlanta area, and the garage door faces west, so it gets extremely hot, as does the garage. We just bought the supplies and will be doing the work tomorrow morning. Thanks for the video.
Good luck with your project! It’s 110° in Las Vegas today. Don’t forget as I said in the video I did have to have my garage door springs adjusted slightly.
@@MrFredsDIY It took 4 days of 4 to 6 hours to do this correctly. It is slow going but it turned out nice and makes a huge temp difference. Again, thanks for the video.
This is by far the best video for insulating a garage door. I added an mini split air conditioner into the garage home gym. Definitely gonna pull this endeavor during the summer.
Thanks for sharing this video. This is quite labor intensive when compared to filling up the space with 1" - 2" solid sheet. It would be great if you could follow up with a thermal scanner video just to confirm if it's worth to take this approach. Thanks again.
With a foil backed foam it needs an air gap or work or the foil aspect is useless and you're just putting foam in. I think this video's process is great, but maybe a bit overkill for the everyday person--I chose to just do one layer instead of the two he did (for ease and finances). But obviously two would be better than one since the air gaps let less and less heat transfer through each subsequent one. In Arizona he probably needs this.
Good luck with your project! I was contemplating this project for quite some time. I wanted to do something more than the normal thick foam kit because it’s so blessed HOT here in Las Vegas. My neighbor has the regular foam and he is happy. I just wanted more lol.
@@MrFredsDIY dude! i just had to start living in my in-laws garage in Las Vegas as well. (mtn. edge) because....well i'm sure you can get a few ideas probably why and one or 2 could probably be correct. Anyway its just killing my wife and I along with are big fatty cat. i was able to get a little a/c unit but its not big enough at all to really feel a difference unless your right next to it. so iv been trying to think of how i can put up make shift walls that will help keep the cool air in a smaller area but my big issue i think is the garage door. by 8:30 -9:00 A.M. i feel that heat just radiant against the door because mine faces south and gets contact from the sun till it starts setting.... i would really like to use the stuff like you did in your video but i cant afford that. i mean i was going to see if i could collect something like really big packing foam from a maybe a fridge or what ever and wrap it in my own foil from the kitchen.. lol its like that for me right now. thank you for your time and video very easy to follow and understand. maybe if you have any ideas or know where i could salvage some scraps so we don't cook and over heat because the rate its going its not looking to good. Not to mention on top of everything i can only work on it at night because its the only time its barrable to work in there but i need to sleep at night so i can get to work in the A.M. sorry for the long message. just had to vent i guess. look forward to seeing more videos. thanks again Levi Patton
@@MrFredsDIY Very good idea, the air gap does create more insulation. I built 2" frame inside my 60" X 60" single pane window, wrap insulation window film with air gap. Really help to keep the cold out.
I'm in SW Florida. My workshop (all steel building, no insulation) is over 80 from early may to early October. Most of those days it is between 100 and 110 during the hottest part of the day. I look forward to this video very much.
I've watched several of these vids and I like this plan the best, the double air gap will help to prevent heat transfer from on substrate to the next. Good plan. Thanks.
I used aluminum duct tape at work. Even when I was careful, I’d get nasty cuts smoothing it. Balling up tape backing to press it is a great way prevent bleeding fingers. Other than that, it is what I’m planning to help my son with. Thanks.
Smart method with the air gap. I'm in the process of fully insulating & conditioning my west facing hot garage so I can do projects year 'round. I like this approach.
Did you measure the difference before and after? That would be interesting to know. Nice job. I like the idea. I would've just like to know the cost value on your method. I live in Phoenix (HOT) and using a foil kit. So changing to your method is it worth the cost. Thanks
Folks have told me that it works for cold weather too. When it’s “cold” here in Las Vegas (35°f) my little Buddy Heater has no problem heating up the garage to film a video or do a project.
Thanks for the great detailed video Mr. Fred. I like your method and will do the same. I found the sheets at Home Depot. How many 4 X 8’ sheets do you need per garage door?
Foil-coated polystyrene (styrofoam) board is (at least in my area) much cheaper than Polyiso, and will perform effectively just as well. As to the "double-sided reflective insulation" - reflective barriers are one-way insulating strategies. The foil facing the outside will reflect radiated heat back to the exterior. The interior-facing reflective barrier will actually be hurting your efforts in a hot climate, as any radiated heat from objects in the garage will be reflected...back into the garage. While the styrofoam can be more fragile if you scrape against it, I found its flexibility to be a bonus, wherein I did not have to cut spacers due to the design of my garage door panels that had a natural crevice for the board sections to hold their place in towards the interior side of the panels. I was able to cup/bend my board sections enough where they popped back into place once inside the metal lip of the door panels. I used no additional tape/foam/glue, and the panels have stayed perfectly in place since I did the project 5 years ago. As to the "added weight/springs" issue some have brought up - polystyrene is also much lighter than Polyiso, such that (personal opinion only) - I saw no need to upgrade my springs, nor have I noted any detrimental effects of the insulation on the door mechanics.
As I watched the video, I did see that the interior-facing reflective barrier was facing into the inside; so, it is safe to say that it should be install facing the garage door(outside) instead?
@@justinjimenez6960, I totally agree with you regarding keeping the heat out; that is why I asked if the reflective barrier should be facing the garage or should be facing away from it. Thanks
Thanks for making this video. I like how you did the edges. What I have done in the past is cut the rigid insulation to fit the gap. Do you think your way is more efficient or better? I'm planning on upgrading mine.
Great Idea Mr. Fred I like the attention in quality and the ( No WRINKLES ) it does make for a aweson finish, I see at the beginning the door was 141 degrees and would like to ask what the temp was after completion the fallowing day, Looks great
Thanks for checking out the video! This winter in Las Vegas has been pretty mild. 45/50 at night. The biggest advantage I have found for winter it that when I use my Buddy Heater it reflects off the door and warms my work area. Thanks for watching!
How would you seal the horizontal gaps on the panels? Is there a piece of stripping you can stick just above the hangs down in front of the gap? Mine has a small draft.
Expense. No builder is going to take on the cost and time unless the homeowners specifically pay for it. And doing it yourself is waaaaay cheaper than paying for an install!
Nice video and great insulation, but if you want the super easy method, you don't have to build a box to get a fairly drastic change in insulation--you can just glue panels right to the door. Just cut 1" thick rectangular panels to your garage panel sizes, then simply put some caulk on a few of the high spots (clean the areas on the door first), slide in the panel and make sure it's resting on the bottom edge of the individual panel areas, press to make sure it has contacted the door/caulk and that's it (some use double sided tape). When measuring for the panels, make sure there's about a 1/4-1/2" overlap so the frame will slightly hold the panel if they come unglued, but mine never did. I did this in Canada north of North Dakota and even when it was like 5 degrees out, I could make the single story garage 50 degrees or more with just a little space heater. Going from a thin layer of highly conductive metal to a door with 1" of insulation makes a massive difference, even if you don't build a box and make an air gap. I just did it on a second garage recently. If you're going to use your garage a ton then I think maybe the box method is worth it, otherwise just slap up some panels ;-)
I wonder how the caulk would last in the insane heat we have? I feel like it might just cook right off. 🤣 I need to get the laser thermometer out, but I’m guessing my garage door gets to his temps or higher. The high today will be 110° F, and the garage faces west with FULL sun for several hours a day. I’m so anxious to try this!
@@davids7209 I don't think you're understanding what everyone is trying to say here. Exterior temp Interior temp before Interior temp after These will indeed dictate its success.
This is great. It keeps the weight down, while having decent R-value and air gaps making it the best option. Only downside is its labor intensive versus other products but if you are going down this rabbit hole then this likely wont be a problem for you
Areas that were clean and dirt free have held up well. I have a few area that I have has to clean better and reapply. I have a follow up video for this on my channel. Thanks for watching!
Well done. I'm in a milder climate however, the humidity makes up for it. I'd like to see some up close assembly shots of what you were doing. The right spacer being shorter confused me as the left should have been shorter as well for the top panel to sit on both evenly, correct? What have you done to combat the exposed aluminum rails? They are essentially heatsinks as well.
Chris High, I think the left side of the door cavity is recessed. The 44" of the top panel does not go inside the recess, but sits on top at all the edges. The top and bottom is the same, not reduced width for top to sit on but to create the "box" edges. Cool project and the little foam strips around the perimeter to make the "cell" is a good effective idea. The little lattice strips should keep the back panel from contacting the doors' surface. Theory is to limit the heat transfer and 2 little contact points hopefully reduce the transfer. I edited my previous post... I watched again and the little scraps he tapes onto the back panel are the spacers to have some support for the top panel and another air gap. That right edge foam strip that goes in before he measures the panel lengths, was not a spacer (works as 1 though), but it was the edge of the "box" and was thinner because the top panel sits on top of it flush with door rails. I was a little confused too. Hope that helps.
The purpose of the lattice is to keep the foam from touching the metal of the door. This will prevent contact heat transfer. Cardboard strips would probably do the same thing.
Looks really good! Thank you for sharing. I live in Arizona and am considering doing this with my garage doors. Just a couple of questions. You used wood spacers tabled to the surface. Do you worry that the heat will release the adhesive and these spacers will end up rattling loose behind the inserted foam panel? Could you have cut your panels from the width dimension, 48”, of the large foam for easier workability and less waste? Have you tested this for effectiveness? Please provide a review video months later if you can. Pros and cons and what you may have done differently. Thank you!
I'm on year two of my installation and haven't noticed any rattling. But I used dryer foil tape and put one on each end of the stick just to make sure it wouldn't slide around. Seems to be holding well because the foam pushes on the sticks anyway.
Would have loved to see the same time of day with similar temps in the same time of year measured before and after. Another user posted that the foil should be pointed outwards, but foil is also conductive, as well as radiative. I think that its a wash between the two, but probably MORE resistant to heat leakage in climates that have colder climates as well when facing inwards.
Thanks for the insights. Having the reflective side inward helps with heating & cooling the garage space (even if only a little). Here is a follow up a year later with more data points. th-cam.com/video/PMiOitCwpak/w-d-xo.html
It does help in the winter too. Here in Las Vegas it can get down to freezing overnight in the winter. I have a small heater I use in the garage and the insulated door helps. Thanks for watching!
I like this design. I wish Fred would have shown how the cells hold up to several garage door openings and closings. I have found that the abuse of the openings and closings can cause insulation like this to start to come out of the door cells over time.
You can take it a step higher and get 1/8" wire rod (I used brazing rod from welding supply/Tractor supply type stores). Drill hole at top & bottom of panel and run rod down, bend at top end to keep in place. Does a nice job.
I have a water heater and a refrigerator in my garage and yes it’s hot in the summer but it’s not to bad in the winter so I’m undecided if I want to do that.I like your choice of materials though and how you put it all together 👍
Man, I wish I would have seen this before I insulated my garage door last year 😢 I did 1" foam throughout.. it works but this looks like it would work a lot better! Maybe on the next one!!! Good job man!
THIS! i saw this after i insulated my garage door and it doesnt look that good so i may end up redoing it with an air gap like this. Makes a lot of sense
Mr. Fred, do you find it also keeps the garage warmer in winter? Here in Texas, I'm sure it will work well in summer, but I'm wondering if it will reduce heat transmission out of the garage in summer?
It’s in the 40’s at night here now so not too cold. When I use my Buddy Heater it seems to reflect off the insulation and keep my work area warmer. Thanks for watching!
Do you have any tips on how to adjust the garage door springs? I love this design and if I'm going to DIY this, I would like to DIY the spring adjustment. I'm just not sure on how much of an adjustment I would need. Any help is appreciated. I love the videos. Keep up the good work.
Thanks for making a great video that’s easy to follow. I do have a question, I noticed that the 1st piece of insulation placed in the door the foil was facing in. I could be wrong but wouldn’t u want the foil to be facing outward towards the source of heat?
Thanks for watching! My understanding is that both sides are foil faced but one side is reflective and the other is painted. Perhaps facing the more reflective side outward would be best.
I used a couple different brands with mixed results. The brand I am using now is called “Flex Fit” and seems to be working well. Time will be the test! Thanks for the question!
Hi there, i want to insulate my single garage door and I live im North east. Will your method help with either cold or hot temps in garage? After I install your method, do I need to adjust for any tension issues on the garage door? Thanks
Yes, I had my garage door guy adjust my springs a bit (they scared me too much to diy). It only gets to freezing a few times each winter here in Las Vegas but when it gets cold my Buddy heater works great. Here is an update video I made with more information ▶️th-cam.com/video/PMiOitCwpak/w-d-xo.htmlsi=fDF0NO13GkdHdAnS
*Great ideal i wish we could have seen you do temp test through out the day. This may work for my situation . Im in texas and Vegas is typically hotter so this should work great. Is it still working well for you ? would you add anything else after having it for a while ?*
Great questions! Every insulation option will add weight to a garage door and Polyiso is no exception. It did add weight to the door and I had my garage door guy adjust my torsion springs to compensate. Here is a follow up video that I made with tons of specific data points. Thanks for watching! th-cam.com/video/PMiOitCwpak/w-d-xo.html
Did you adjust door springs to account for added weight? Even though weight seems light there are added lbs to the door which can affect door openers function. Just thinking out loud. Your system appears to be so much more energy efficient.
Thanks for commenting. The springs were adjusted, I had my garage door guy do that for me. Here is a follow up video with tons more information.th-cam.com/video/PMiOitCwpak/w-d-xo.htmlsi=fs3Rf6SlQ2CM1a2c
Wow! Nice. What R value do you estimate you achieved? Also, did you measure temperature inside and out after completion? That would be very useful to know.
Like the design. You say 8 sheets of 4x8 will do the entire door? Assuming door is 16' wide by 8' tall. I was guessing given two layers and the edge pieces might take a sheet more?? Thanks a lot!
It gets cold here in Las Vegas at night and some days in the winter also. It makes a difference! Here is a follow up video with more temperature statistics.Garage Door Insulated The Right Way (Proof It Works) th-cam.com/video/PMiOitCwpak/w-d-xo.html
Thanks for the comments! I made a follow up video that has lots of temperature data points. That video is right here ▶️th-cam.com/video/PMiOitCwpak/w-d-xo.html
Excellent video. I am just about finished with insulating two garage doors. The only issue I am having is the recommended tape is curling on the edges. I did clean the surface with alcohol, but it is still curling away. I may have to source another brand of tape to seal everything. Not happy about that.
You did a great job with the design, and explaining it, and then demonstrating the installation. You failed, however, to show a before and after temperature reading. You responded to comments asking about it but only by saying that the inside door temp was basically the same as the air temp inside the garage. You never gave us any numbers. What is the air temp in the garage!! Give us some sort of reference to know just how well it worked. Not doing so makes me wonder if you were disappointed with the results and don't want to get too specific with the results. The proof is in the numbers.
I agree also, I watched the entire video to see the end results of all the work and money invested. I live in Phoenix and have the same heat problem but without seeing the end temps for the inside on this build it was a waste.
He said it was 117 degrees outside, without humidity in AZ and based on what he's wearing and not sweating it probably drops the temp about 25-30 degrees. We did this to our garage with temps in high 90's and high humidity and it cooled it to mid 70's

I just saw another video doing something similar, but he was in a cold climate and did not do the cell My garage door faces north I’m in the Pacific NW, so do I need to do this extra step? I’m just trying to insulate the garage a little more
I like this idea…I don’t like the tape showing because I’m a little OCD. But I do need some horizontal bars to reinforce my door from winds .. (Oklahoma) ..the bars could hold the foam in place…I need to think about this. Thanks for the idea for sure! What was the post instal temp? 😂
One more question Fred please. On each of the metal connections running vertically there is a deep space probably 3 inches or so. How would I fill that area?
any suggestions on how do this install when your garage door does not have a frame for the cell to lie on? The inside of my garage door just has the hinges, but no horizontal or vertical frame for each rectangle. i could just tape the first spacers directly onto the door, but am worried that the tape wont hold all the weight from the entire cell over time?
Here is the follow up video I made for this one. Lots of temperature data. th-cam.com/video/PMiOitCwpak/w-d-xo.htmlsi=aAXWGDMC5I8qzwmX

@@JoseMartinez-dk1pw Depends on your climate and desires. In South TX, I’m far more interested in keeping heat out than keeping heat in.
@@justinjimenez6960, I totally agree with you regarding keeping the heat out; that is why I asked if the reflective barrier should be facing the garage or should be facing away from it. Thanks
I’m not an expert but I imagine if you’re in a climate that gets cold as well as hot you’d find it beneficial to help keep heat inside in the winters?
@@benjaminking5450 Yup. Whatever your need case is. For me, I've never lived anywhere I wanted to keep heat in.
Like what you did. Planning to do mine soon. It is very cold in Columbus, OH
Thanks for making this video. I like how you did the edges. What I have done in the past is cut the rigid insulation to fit the gap. Do you think your way is more efficient or better? I'm planning on upgrading mine.
How well does this work for cold temperatures?
Here in Las Vegas it only gets down to freezing a few times per winter buy when it does, Buddy Heater makes the garage pretty comfortable.
Great Idea Mr. Fred I like the attention in quality and the ( No WRINKLES ) it does make for a aweson finish, I see at the beginning the door was 141 degrees and would like to ask what the temp was after completion the fallowing day, Looks great
The inside surface temperature of the door is always within a few degrees of the ambient temperature of the garage.
Would really enjoy seeing a video regarding winter temps in your garage...Thanks!
Thanks for checking out the video! This winter in Las Vegas has been pretty mild. 45/50 at night. The biggest advantage I have found for winter it that when I use my Buddy Heater it reflects off the door and warms my work area. Thanks for watching!
How would you seal the horizontal gaps on the panels? Is there a piece of stripping you can stick just above the hangs down in front of the gap? Mine has a small draft.
Thanks for watching! I am not aware of a product for that situation. If I come across one I’ll post a link.
I wish you would have shown the thermal difference.
Makes me wonder why this isn’t just standard practice in warmer climates. Thanks for the video!
Expense. No builder is going to take on the cost and time unless the homeowners specifically pay for it. And doing it yourself is waaaaay cheaper than paying for an install!
Here is a follow up I just finished th-cam.com/video/PMiOitCwpak/w-d-xo.html
Nice video and great insulation, but if you want the super easy method, you don't have to build a box to get a fairly drastic change in insulation--you can just glue panels right to the door. Just cut 1" thick rectangular panels to your garage panel sizes, then simply put some caulk on a few of the high spots (clean the areas on the door first), slide in the panel and make sure it's resting on the bottom edge of the individual panel areas, press to make sure it has contacted the door/caulk and that's it (some use double sided tape). When measuring for the panels, make sure there's about a 1/4-1/2" overlap so the frame will slightly hold the panel if they come unglued, but mine never did.
I did this in Canada north of North Dakota and even when it was like 5 degrees out, I could make the single story garage 50 degrees or more with just a little space heater.
Going from a thin layer of highly conductive metal to a door with 1" of insulation makes a massive difference, even if you don't build a box and make an air gap. I just did it on a second garage recently. If you're going to use your garage a ton then I think maybe the box method is worth it, otherwise just slap up some panels ;-)
I wonder how the caulk would last in the insane heat we have? I feel like it might just cook right off. 🤣 I need to get the laser thermometer out, but I’m guessing my garage door gets to his temps or higher. The high today will be 110° F, and the garage faces west with FULL sun for several hours a day. I’m so anxious to try this!
the air gap will add more than you think to the R value
Thanks for the solid video. Ill be trying this when I get see time in the next few weeks in preparation for summer
Good luck with your project! Here is a follow up video that I made with more information ➡️th-cam.com/video/PMiOitCwpak/w-d-xo.html
Wish you'd have shown the exterior temperature outside and inside before and after
Yes this update is needed.
@@HotmailHacks Here is an update I just finished th-cam.com/video/PMiOitCwpak/w-d-xo.html
The exterior temperature shouldn't change.... it the interior temp that changes. If the exterior does change it will be very slight.
@@davids7209 I don't think you're understanding what everyone is trying to say here.
Exterior temp
Interior temp before
Interior temp after
These will indeed dictate its success.
This is great. It keeps the weight down, while having decent R-value and air gaps making it the best option. Only downside is its labor intensive versus other products but if you are going down this rabbit hole then this likely wont be a problem for you
I like the idea up to the tape. Not sure if the tape will hold up. After a year, did it?
Areas that were clean and dirt free have held up well. I have a few area that I have has to clean better and reapply. I have a follow up video for this on my channel. Thanks for watching!
Well done. I'm in a milder climate however, the humidity makes up for it. I'd like to see some up close assembly shots of what you were doing. The right spacer being shorter confused me as the left should have been shorter as well for the top panel to sit on both evenly, correct? What have you done to combat the exposed aluminum rails? They are essentially heatsinks as well.
Chris High, I think the left side of the door cavity is recessed. The 44" of the top panel does not go inside the recess, but sits on top at all the edges. The top and bottom is the same, not reduced width for top to sit on but to create the "box" edges.
Cool project and the little foam strips around the perimeter to make the "cell" is a good effective idea. The little lattice strips should keep the back panel from contacting the doors' surface. Theory is to limit the heat transfer and 2 little contact points hopefully reduce the transfer.
I edited my previous post... I watched again and the little scraps he tapes onto the back panel are the spacers to have some support for the top panel and another air gap. That right edge foam strip that goes in before he measures the panel lengths, was not a spacer (works as 1 though), but it was the edge of the "box" and was thinner because the top panel sits on top of it flush with door rails. I was a little confused too. Hope that helps.
Can i just use the insulation board for the front panel also or do i need the lattice wood. Thanks
The purpose of the lattice is to keep the foam from touching the metal of the door. This will prevent contact heat transfer. Cardboard strips would probably do the same thing.
Thanks. I just can't find the 1/4 x 1/2 lattice wood.
Looks really good! Thank you for sharing. I live in Arizona and am considering doing this with my garage doors. Just a couple of questions. You used wood spacers tabled to the surface. Do you worry that the heat will release the adhesive and these spacers will end up rattling loose behind the inserted foam panel? Could you have cut your panels from the width dimension, 48”, of the large foam for easier workability and less waste? Have you tested this for effectiveness? Please provide a review video months later if you can. Pros and cons and what you may have done differently. Thank you!
I'm on year two of my installation and haven't noticed any rattling. But I used dryer foil tape and put one on each end of the stick just to make sure it wouldn't slide around. Seems to be holding well because the foam pushes on the sticks anyway.
Would have loved to see the same time of day with similar temps in the same time of year measured before and after. Another user posted that the foil should be pointed outwards, but foil is also conductive, as well as radiative. I think that its a wash between the two, but probably MORE resistant to heat leakage in climates that have colder climates as well when facing inwards.
Thanks for the insights. Having the reflective side inward helps with heating & cooling the garage space (even if only a little). Here is a follow up a year later with more data points. th-cam.com/video/PMiOitCwpak/w-d-xo.html
The foil should be facing inwards with the white part facing out. It helps with IR barrier
How did this help out in the winter? Two of my rooms sit over the garage so it gets extra cold. Will this also help with that?
It does help in the winter too. Here in Las Vegas it can get down to freezing overnight in the winter. I have a small heater I use in the garage and the insulated door helps. Thanks for watching!
thanks, i did it w/o the slats but good idea on them, maybe next time
I was hoping to see some Before AND after temp readings. Hows it do in the cold?
I made a follow up video that has more temperature data. That video is on my channel. This insulation performs well in our Las Vegas cold climate too.
I like this design. I wish Fred would have shown how the cells hold up to several garage door openings and closings. I have found that the abuse of the openings and closings can cause insulation like this to start to come out of the door cells over time.
You can take it a step higher and get 1/8" wire rod (I used brazing rod from welding supply/Tractor supply type stores). Drill hole at top & bottom of panel and run rod down, bend at top end to keep in place. Does a nice job.
I have a water heater and a refrigerator in my garage and yes it’s hot in the summer but it’s not to bad in the winter so I’m undecided if I want to do that.I like your choice of materials though and how you put it all together 👍
You are a genius and a great communicator! I enjoyed this video very much! Thank you.
Thanks for checking out the video!
Awesome video! Would you do everything the same if you were concerned about a couple months of very cold weather?
If I were in a mild climate perhaps I would do a single layer to cut down on cost. Thanks for watching!
Man, I wish I would have seen this before I insulated my garage door last year 😢 I did 1" foam throughout.. it works but this looks like it would work a lot better! Maybe on the next one!!! Good job man!
I appreciate you taking the time to comment and thank you for watching!
THIS! i saw this after i insulated my garage door and it doesnt look that good so i may end up redoing it with an air gap like this. Makes a lot of sense
Mr. Fred, do you find it also keeps the garage warmer in winter? Here in Texas, I'm sure it will work well in summer, but I'm wondering if it will reduce heat transmission out of the garage in summer?
It’s in the 40’s at night here now so not too cold. When I use my Buddy Heater it seems to reflect off the insulation and keep my work area warmer. Thanks for watching!
Hello very good video!! What kind of tape are you using?? Thanks
Thanks for watching the video! The rape is Multi-Purpose Foil Tape, 46m Length, 48 mm Width, Aluminum
amzn.to/3iWcKaK
Do you have any tips on how to adjust the garage door springs? I love this design and if I'm going to DIY this, I would like to DIY the spring adjustment. I'm just not sure on how much of an adjustment I would need. Any help is appreciated. I love the videos. Keep up the good work.
Thanks for commenting! Those torsion springs scare me so I called my garage door guy.
Thanks for making a great video that’s easy to follow. I do have a question, I noticed that the 1st piece of insulation placed in the door the foil was facing in. I could be wrong but wouldn’t u want the foil to be facing outward towards the source of heat?
Thanks for watching! My understanding is that both sides are foil faced but one side is reflective and the other is painted. Perhaps facing the more reflective side outward would be best.
Can you explain what tape you used? I've tried using duct tape and it has failed on several areas.Thanks
I used a couple different brands with mixed results. The brand I am using now is called “Flex Fit” and seems to be working well. Time will be the test! Thanks for the question!
You are my new hero.
Hi there, i want to insulate my single garage door and I live im North east. Will your method help with either cold or hot temps in garage? After I install your method, do I need to adjust for any tension issues on the garage door? Thanks
Yes, I had my garage door guy adjust my springs a bit (they scared me too much to diy). It only gets to freezing a few times each winter here in Las Vegas but when it gets cold my Buddy heater works great. Here is an update video I made with more information ▶️th-cam.com/video/PMiOitCwpak/w-d-xo.htmlsi=fDF0NO13GkdHdAnS
Thank you so much. I'll do it at my studio garage in Florida.
*Great ideal i wish we could have seen you do temp test through out the day. This may work for my situation . Im in texas and Vegas is typically hotter so this should work great. Is it still working well for you ? would you add anything else after having it for a while ?*
Here is a follow up for the video with lots of temperature data th-cam.com/video/PMiOitCwpak/w-d-xo.htmlsi=A56m3zgpEA_b82xg
Would this work well for cold weather or is there something different you would do in colder weather?
If I were in a colder climate I would probably do it the same way. Thanks for watching!
Great video! An extra bonus would be an explanation of just how effective it is at keeping the garage cooler.
A follow-up video is in the queue! Coming in July. Thanks for watching!

How much weight does that add to the garage door and does it affect the opening and closing?
Great questions! Every insulation option will add weight to a garage door and Polyiso is no exception. It did add weight to the door and I had my garage door guy adjust my torsion springs to compensate. Here is a follow up video that I made with tons of specific data points. Thanks for watching! th-cam.com/video/PMiOitCwpak/w-d-xo.html
Did you adjust door springs to account for added weight? Even though weight seems light there are added lbs to the door which can affect door openers function. Just thinking out loud. Your system appears to be so much more energy efficient.
Thanks for commenting. The springs were adjusted, I had my garage door guy do that for me. Here is a follow up video with tons more information.th-cam.com/video/PMiOitCwpak/w-d-xo.htmlsi=fs3Rf6SlQ2CM1a2c
AWSOME....... im doing this... great video
Wow! Nice. What R value do you estimate you achieved? Also, did you measure temperature inside and out after completion? That would be very useful to know.
Here is a follow up I just finished. Thanks for watching th-cam.com/video/PMiOitCwpak/w-d-xo.html
Like the design. You say 8 sheets of 4x8 will do the entire door? Assuming door is 16' wide by 8' tall. I was guessing given two layers and the edge pieces might take a sheet more?? Thanks a lot!
as a fellow Las Vegan you're a legend

So does all this foam adds extra weight for the motor . It won’t over work it ?
Great question! For me, this process added about 25 pounds. I had my garage door guy. Adjust my torsion springs to compensate.
Excellent video. I am just about finished with insulating two garage doors. The only issue I am having is the recommended tape is curling on the edges. I did clean the surface with alcohol, but it is still curling away. I may have to source another brand of tape to seal everything. Not happy about that.
Thank you very much, very helpful, I'll try to do it myself👌😊
FREAKING AWESOME !!
You did a great job with the design, and explaining it, and then demonstrating the installation. You failed, however, to show a before and after temperature reading. You responded to comments asking about it but only by saying that the inside door temp was basically the same as the air temp inside the garage. You never gave us any numbers. What is the air temp in the garage!! Give us some sort of reference to know just how well it worked. Not doing so makes me wonder if you were disappointed with the results and don't want to get too specific with the results. The proof is in the numbers.
Yeah what a waste of a video. No facts
I agree!
I agree also, I watched the entire video to see the end results of all the work and money invested. I live in Phoenix and have the same heat problem but without seeing the end temps for the inside on this build it was a waste.
@@znelson32 Thanks for checking out the video. I just finished the follow-up th-cam.com/video/PMiOitCwpak/w-d-xo.html
He said it was 117 degrees outside, without humidity in AZ and based on what he's wearing and not sweating it probably drops the temp about 25-30 degrees. We did this to our garage with temps in high 90's and high humidity and it cooled it to mid 70's
What was the temperature of the inner wall after the insulation was added?
Can you do this for a vertical attic 🚪, so much heat comes from the attic through that door.
Polyiso is used in many applications including roofing. Perhaps your attic is not ventilated properly? Thanks for watching.!
I'd like to know the before and after temperature inside the garage to see how much difference?😊❤

I am in Northern climate. I used foam kit. Quick question: with foam do you still recommend tape?
I’ve had good luck with foil tape. If you do go that route I recommend spending extra time cleaning and preparing the surfaces. Thanks for watching!
wonder if new springs would be needed?
My garage door guy adjusted mine. He said new springs weren’t necessary for me. Thanks for watching!
I just saw another video doing something similar, but he was in a cold climate and did not do the cell

@@MrFredsDIY wow that is a huge improvement
I like this idea…I don’t like the tape showing because I’m a little OCD. But I do need some horizontal bars to reinforce my door from winds .. (Oklahoma) ..the bars could hold the foam in place…I need to think about this. Thanks for the idea for sure! What was the post instal temp? 😂
Thanks for the view! Here is a follow up video that has tons of temperature data!
Thanks for the demo and info, have a great day
Thanks for watching!
Just curious, shouldn't the reflective side (foil side) face out to reflect the heat?
Maybe I missed it but did you happen to do a before and after temperature check on the garage door from the interior?
Will this affect the garage door torsion springs? Wonder how much weight was gained
Well done bro 👍🏼😬
My local spot doesn’t have 1.25 inch by 1/2 inch lattice. Anything else I can use.
You can use any thin wooden trim stock that keeps the Polyiso away from contacting the metal. Good luck with your project!
One more question Fred please. On each of the metal connections running vertically there is a deep space probably 3 inches or so. How would I fill that area?
@adhab those spaces on my door are open on one side so i was able to put one layer of foam inside.
Do you know what is the equalavance of the R value with this insulation ?
This was an outstanding video, great job!
I live nebraska so my question is does it work to keep cold out in cold weather also?
Great idea and great video.
Ok. That is maybe effective for hot climates. I'm on the Canadian border where -30 happens. Is this method effective for cold temps?
Great question! Here in sunny Las Vegas it works. Hot or cold should be similar. Still, it is a good question.
What was the temperature difference after you were done?
Here is a follow up video with tons of temperatures ➡️th-cam.com/video/PMiOitCwpak/w-d-xo.html
any suggestions on how do this install when your garage door does not have a frame for the cell to lie on? The inside of my garage door just has the hinges, but no horizontal or vertical frame for each rectangle. i could just tape the first spacers directly onto the door, but am worried that the tape wont hold all the weight from the entire cell over time?
Did I miss the temp check after you put in the insulation?
