If you don’t mind explaining why did you do it yourself? The insulation contractors charge per board foot installed (sprayed) for essentially the same price as you bought the material for . So you save your labor and let them deal with the mess. Also you didn’t tell is this a closed or open cell?? I like you live around Detroit and doing almost same thing as you with the house I bought last year, so I got to the insulation part and wondering what you can say about that. Thanks

Agreed with the no ventilation. My concern is with the spray not being directly on the wood. You are basically creating an uncontrolled air gap between that foamboard and the wood. Heat will transfer to the cold air in that gap. As temperature of the air changes in the gap, it will condensate and create moisture. Many builders say to put a sheet like you did. Spray manufacturer says to spray directly on wood. I converted my flat roof and i sprayed directly on the osb. Studies/research at building science really help me.

The cans were never designed for open bay sealing, just small holes, corners, cracks, edges, between studs, windows and doors, etc. They can be used for the gaps between exterior sheathing, around bases and tops of wall plates, aswell as corners were studs meet sheathing, sill plates, anywhere drafts can squeeze through. I love using it in joist bays in combination with 2 or 3 inch XPS foam board. I cut them 1 inch shy dimensionally, use screws or nails to hold/pinch em in place, then fill around the perimeter with the can foam. This is a far easier, cleaner and great method to air seal these cavities on a budget before adding batt insulation.

I would've liked to have seen you use the cans.

The cans worked SOOOO much better for me. And way cheaper. Just use the correct tip (they come with two different kinds, one for walls and one for ceilings) on the gun and the results were even and smooth. Not sure what you were doing wrong because you didn't include any footage of using them in the video.

Glad to see you had some success with the kit. I've seen a lot of bad info about those kits. Difficult to use, and a fairly large investment for something so easily messed up. I personally just use the smaller cans for the small things and typical fiberglass batt insulation.

I found extremely effective at insulating my cellar ceiling and joists. Its the covered porch above. Made a great air tight seal. Looks like the bottles i had saved are no good. Considering theyre 2 years old now LOL good video as always

This is so different to build / renovate than buildings here in germany that it is very interesting, thx for showing !

Dont you want ventilation for mold protection?????

So if anyone asked. About a ridge vent they don't know anything about insulation

I work with the commercual version of this stuff in the factory.

Thanks for your video, I've been wondering about the particulars of using those kits for a while now. I would maybe zip-tie the cans together to move them easier! You are a hard worker, keep it up!

About to spray foam my attic, video came at just the right time. Thanks !

Thanks for the video, I was wondering about the one can solution

we used those cylinders at work they were a pain to keep hoses from clogging if you didn't use it fast enough, we coated ends of tips with Vaseline to get a better seal and not have hoses clog when not using them constantly had to keep spraying into a cardboard box to keep tip from clogging.

Thanks for sharing 😀

Man I watched the roof video.

It would be nice to have a insulated cover of some sort to keep contents of the cans warm while using. Will help keep the spray consistent.

I'm thinking about using the 2 cylinder system but will practice on my shed first, then my house.

Great video! Can I ask a couple questions? I’m planning to spray my wooden ceiling, but a few people warned me that the foam may hinder the expansion and retraction of the wooden structure possibly damaging it. Is that true? Second, do you recommend to put the air chamber first the spray it?
