- Thank you so much for making this video a HUGE success. Please like and most importantly subscribe so you can see our latest videos. Okay now back to the video . Here we show a difficult dormer roof being sprayfoamed and then the foam is "cut flush" or shaved flush to allow the drywall contractor get a perfect air tight seal . Chech out more of our videos on www.fusioninsulation.com or www.fusioninsulation.com/attic-insulation
Because of the success of our video I get asked a lot about where the foam saw featured in the video can be purchased .
Heres a link :

PS: I haven't been given any incentive to recommend this chap . I have bought equipment from him and found him to be very helpful and efficient. - แนวปฏิบัติและการใช้ชีวิต
This is really satisfying to watch.
Thanks
i could watch hours of this. wondering how perfect weather that space became. Inspiring.
hi everyone ,if anyone else wants to uncover container home designs plans try Jadonite Shipping Container Buddy ( search on google ) ? Ive heard some extraordinary things about it and my buddy got excellent success with it.
Great video demonstrating the overall process
Thanks - we appreciate the feedback
I couldn't stop watching
Quality work right there.
That guy is a good sprayer. Fast, minimum of waste. Did you see how uniform the slices were when he was shaving down to the studs?
+Jame Donovan yep! I did. I'd hire him any day.
This is one of those "satisfying " videos.. I could watch that foam being trimmed, all day ahhhhhh
nice blade on that saw, dont see those for sale in home depot or lowes
Without any extras (ventilation baffles, etc) what is the approximate cost per square foot in standard 2x4 stud bays?
You should tape those black vents together.. everytime he sprayed at a seam, it went behind the black vent, which probably expanded just enough to close off the ventilation air way from the soffit to ridge vent
I love this technique. I've spent hours installing fiberglass. Hated it. Tedious and itchy while I have my misgivings about how well it performs. This stuff sticks tight and is firm. Even rats would have a hard go of it. Fiberglass is a perfect home for rats and mice. Especially under a trailer home.
John Knoefler Mice,rats,bugs & virtually all rodents avoid the spray foam.they will not eat through it,so it is a saviour in more than one way.
John Knoefler i had an animal trying to get into my loft the other day and I sealed it with foam and it's given up now so it's excellent stuff
Inspecting a friend's attic the fiberglass insulation was matted down by rats, cats and and mice. Filled with feces. What a mess to clean out and replace.
yes , very satisfying
thanks
Nice neat job by the technician.... Plus he is laying thin layers at a time.... That way you will be assured there will be no uncured foam that remains in liquid state., which could off gas forever.. Seems the liquid chemicals used to make the foam are relatively unsafe to breathe in liquid form.... But become harmless after the chemical reaction has taken place and turned the liquid into a solid foam core... As in a Styrofoam cup we drink coffee out of....
But what do I know anyway? I slept at a Holiday Inn last night.
+mrpearl1 Actually it sounds to me like you know quite a bit. You know more than the majority of these commenters. And yes I have sprayed foam before. :)
My god I wanna jump in there and do that badly I'm sure that guy makes it look easier than it is but wow so satisfying unless you do it 24/7
As I like to say about some jobs, "It's only interesting during the first 3 hours."
Hello guys,
is that home made blade?
Could you give some more info about it.
Regards
That's perfect. If I had foaming done Id want the cavity full. Those that leave gaps are NOT maximizing the insulation value.
peterincgy open cell foam is done this way. closed cell is left just shy of the interior of the rafters, due to difficulty of trimming.
I'm taking this has a lot of benefits
open cell foam gives you breathability and insulation in one system . if you use it with a breatheable roof membrane any water vapour entering the roof void can pass through the OC foam and then out through your permeable roof membrane
this seems really helpful, where can I get this?! how much does it cost?!,
This is a cool video... I thought that you shouldn't spray ever still wet foam. Something about fish smells and not curring correctly.
muy buen trabajo felicitaciones muy térmico eso
good job guys..we still using hand saw scarfing blade
So cool
What are you using to form the air channel between the insulation and underside of roof deck?
what kind of blade does he use on the sabresaw? (reciprozaag)
since I am in the states, what brand foam is this? I may have to try this myself.
While the R index of that new wall will be huge, what of the concrete block wall nearby?
where do you get those extra long reciprocating saw blades?
That's the same question I had
very very good job how much machine end materials???????
have you ever tried to mix that kind of foam with another fireprooof material?
Is he being being very efficient with his time, given his application method?
Any OUT GASING after? Oh hour many years after covering
If 1/8 of spacing between roof sheeting is required by code to release preasure from the attic during storms how is it code compliant to seal off what the code calls for
i could watch this forever
oddly satisfying...
What do they do with the cut off's? I it recyclable?
Is this foam hard too cut into in case of plumbing problems
I am new to this insulation thing, I need to install something into a metal shed 20X40 with raised four inch rails inside what do you think?
What is necessary insulation for a home on pillars.
Would you spray foam it then sheath it with a r_3 foam board on the underside joists ?
Probably the other way around - fit the foam boards in a warm roof construction and then spray foam oto same - ideal combination
Good vidio.
can this foam be used to do the ceiling joist in an attic space as well or is it only used roof/slate side?
Yes ceiling joists can be easily sprayed
Hello, how does this foam handle acoustic isolation? Have you tried it in Music Studios lets say? Thanks
Yes - open cell has positive acoustic properties - We have sprayed a recording studio and commercial buildings including a large dog pound that wanted to cut down on dog barking sounds at night. Worked a treat.

Im watching this because its really hot in miami and im dreaming of having all that foam
Does cutting it decrease efficiency? I was told that I need 5 inches and cutting it brings it below 4? Thank you I just want to make sure my job is done right!
Nice
The blade is so flexible I wonder if it leaves a convex cut between studs
hola. que herramienta es la utilizada para cortar la espuma? saludo.
We use a reciprocating sawzall saw

what blade is that you are using to scarf ?

Hope that helps buddy ;-)
did you have to buy it from the states or is there a uk or europe based company
Looks like buttercream icing.
Nice demo, guys!
Thanks - I get a lost of inquiries from the States for reciprocating sawzall saw blades and equip .Please post a link if you stock these - I don't have a dog in this fight
Unfortunately, we do not. We distribute polyurethane equipment such as; proportioners, spray guns, hoses, drum heaters, rig building, trainiing, etc. www.sprayworksequipment.com

Is der any chemical which can melt dis foam ??????plz ans
Do you need the black paper attached before spraying? Was that applied for the the foam? I talked to a professional and he never mentioned applying a black paper.
Davian - the black paper system is a spacer card that we have to fit in Irish roofs under local regulations - It's a bit of an anomaly in terms of regulation as for example if you fit Icynene foam in Ireland you don't have to fit it but if you spray all the other certified foams you do (even though they are all pretty much identical open cell foams ) - go figure
Is it flammable ?
not once it's cured. It's actually fairly fire retardant.
I don't think its highly flammable product, but if the house is on fire either spray foam or normal isolation will survive
That is 1 large, electric bread knife
Is it available in india
for what he is doing that?
Why not used closed cell?
You could use closed cell . In this case open cell was preferred as it's breatheable and cheaper when compared mm to mm or inch to inch
How much does this cost for a 1,300 sq ft home?
ok good
Wat dose it cost

must be my gun, have a much more even spray that looks to fill a bit more evenly?
Can you put like a paper surface on it so it's not a permanent thing? So you can pull it off later?
The narrator sounds like Chris O'Dowd!
could u give me product name please?
The mask looks so terrifying :D
Finally, 1 guy that knows what the hell he is doing.
So many houses have been destroyed by so-called professionals but this is the first 1 I see.
But still, I would recommend not using spray foam insulation.
If only that it looks horrible.
Glasswool and place some boards over it for a much cleaner look.
Just wondering, What kind of R Value would this ceiling have with that much spray foam?
Look up open cell foam insulation for the one in this video. Typically 3.5 - 4 per inch on the half pound psqft. Closed cell (2 lb psqft) 6.5 - 7 per inch
It's very nice, however it looks like there is a lot of wasted material ones he starts cutting off the excess foam!
Elamar - we hate waste also - we bag the trimmings on site, always and many customer use the offcuts as additional insulation in other voids in their roofs, crawls spaces and floor joist cavities - so it's not always wasted . If anyone has a good idea on recycling foam trimmings I'm all ears ?
You could possible run the excess insulation through a wood chipper or something similar. That way, it would be a very fine material that could be used in ceilings or attics. Just a thought :)
fusioninsulation The little waste of insulation is minor compared to energy loss from other poor insulations. I’m more interested in where you got that saw blade! Love the results of this job.
What about cost/price? Is it expensive?
Antonio Jose Padilha HELL YEA IT IS
What kind of saw is that for cutting it flush?
Its a milwaukee sawzall with foam blades -most of the foam equip suppliers sell the blades
e caro o equipamento?
This documentary sounds like it was narrated by Chris O'Dowd
is that saran wrap over his mask? good idea! or is it something els. Its a pain having to spray flush with joists, lots of wasted material ends up on the floor. is that just a sawsall with a long saw attachment?
I figured we would of developed a more convenient tool than a 4’ reciprocating blade

can i mix color in Polyurethane?
+Ahmed Sakaw -manufacturers add colour to identify their foam . BASF have purple so yes you could do it but you'd need to be expert in it
I did do it before and dont know how .. can u tell me how plz mix colour in polyurethane? .. I need do that in my work
You can, but no matter what color you dye it it will always want to yellow. Your best bet is to paint it. Even corbon's purple foam turns an ugly lime green color after a year of lite uv exposure.
It's 12:52AM. Why am I watching this?!
Why would you ever leave an air space behind the foam? According to everything I have read and studied this will only create problems. The air space is to allow moisture to dry and have a place to go. With foam against the plywood there will be no moisture to vent. What is the logic or thought here? I am interested to hear why.
+mfmanuele We are required by building code in Ireland to put in this spacer . Lots of disagreement over its use , but hey I dont write the rules - Thanks for the comment :-)
There should be a vented air gap between the insulation and the exterior sheathing. Here is a video where the guy that helps right the codes give the reason. He can say it better than I. th-cam.com/video/Ld8pzIu45F8/w-d-xo.html
So, what about in Southern California? We have little rain, humidity is relatively low most of the year. Maybe skip the air space and spray directly against a plywood roof sheath?
One thing I have learned every country has it’s known codes
Because of condensation from the roof.
where are this guy's gloves?
Both of my guys are wearing gloves and PPE
On his hands!
Good day sir can i ask you some think sir,its that polyurethane ?
Yes, it is
Good to watch but seems really slow , I could do that quicker with kingspan a saw and a step ladder .
someone who knows the name of the machine to cut

Definitely not faster than batt insulation, but better.
Can I have a job
Whats the purpose of the foam? Is it to make waterproof?
Wouldn’t recommend open in a roofline..
Go with Close Cell, better R-Value
That looks like a p2 gun to me. Not a fusion. Your spray technic is a good way to make bad foam in a hurry. 1 inch minimum lifts at a time. Its a chemical reaction which requires the heat of the foam to react properly
+dsfi2010 heat control is important. You do not want too much heat. This guy is doing it correctly.
unbelieveable how many people think the right thing to do is gob a ton on at one time, heat is the enemy here, all it takes is one mistake to end up with a runaway endothermic reaction that will ruin a house
+consaka1 you also need enough heat for a proper chemical reaction. Less than an inch does not produce enough exothermic heat to make good plastic. Some foams you can't spray more than 2 inch lift without problems, but you still need more than 1. Some newer good foams will do 3 inches plus without issues. All still require a minimum thickness to get a proper exothermic reaction. Really small lifts also give you shitty yields, to top it.
Christopher Gruenwald I have done this before so why are you telling me? This guy is doing the job properly and doing an excellent job controlling the heat. you don't want too much heat or too little heat.
why not just use the polysterene sheets and cut to fit , got be less messy and no nasty smells
Sheet insulation is okay I guess . You have to allow for 5-7% wastage , cut each sheet individually and then they are not airtight so you have to buy dozens and dozens (I've seen hundreds of cans used on big jobs) of DIY foam cans to caulk the sheets to make them airtight ....and you have to project manage and QC all that . Getting us in takes just 1 phone call and we clean up after us .
Where can people rent foam blowers? No use to pay someone to do this
Does it need a vapor barrier after cutting all that foam? The “closed cells” are no longer closed
If it’s not harmful for you why’s the guy have a suit with a respirator for breathing?
You shouldn't have to scarf all that when your foam looks like stucco maybe Half pound is your thing
+Grezzy42 As we mentioned we're spraying half pound open cell foam here not 2lb . You'd struggle to cut 2lb this easy . I'm not saying that cutting off overspray is the most efficient use of foam but customers demand it so that is what we do for them . As the old adage goes 'Whats the first function of any business ? To create a satisfied customer"
you might be right .Personally I don't like cutting foam , it removes the 'skin' off the foam which is the best part of the foam
Spray me
Half pound is easy
Hey you missed a spot.
Wow..this is a slow way to spray...I would spray one cavity a 5 inches in one pass..skip one cavity then spray the next..I would cut the cavity wher I wouldn't have the foam in my way..then go back a spray the cavity I skipped
wow what a waist
