Ey Cory I just subscrbe to your channel. One question I did look for something that would talk aboutthe best option to insulate an existin house. I just purchase a house but it was no insulation.I wanted to apply insulation to all exterior walls. The exterior is brick. I was thinking using sprayed insulation trough the interior walls. But I dont know if running pipes or electrical wiring will become an issue in the future. Also I have a lot of windows, What would you reccommend for best option.?

@pocho31 Hey Pocho31, If you have no insulation in the walls, I'm going to bet you have a poorly insulated attic as well. The first thing I would do is air seal and insulate the attic to R50 or above. It's the cheapest and easiest place to insulate. It will also give you the biggest bang for your buck.

Then I would get bids from several insulation contractors for both slow rise spray foam and dense pack cellulose. DIY slow rise foam kits are available but extremely expensive for a whole house.

thanks for the great video. I would imagine that to do this in a crawl space would be almost impossible. Do you recommend any brands of closed spray foam for a DIY job? Thanks.

[HowToHomeInsulation]

@modblogger1 It would be tough to squeeze through a crawlspace opening and not a lot of fun. But if you have to cut the foam board in smaller pieces and then reassemble it. You can use an acrylic tape like Tyvek tape to put the puzzle back together.

As for spray foam kits...I'd use a Dow Froth-Pak or a kit from Spray Foam Direct

Thanks for watching!

I think 2" is not enough even for 2x4 wall. I mean if you have 21C inside and -10C outside in humid areas your due point is outside of your insulation you're gonna get water condensation problems. With air tight walls you created and woodframe this calls for mold disaster... as Important as energy efficient your suggestion is I think you should mention where this is not applicable.

R12 is not very much. Standard 2 x6 studs with fiberglass gets R20. Granted most older homes have 2x4. Me personalty would go with 2 times 2x6 offset.

How bout a garage ceiling (vaulted) first with some fiberglass in the bays and then hang some iso board on the rafters like drywall and tape with duct board tape , would that create a mold issue at the roofs bottom plywood deck ????

@2bloud uh? nooooo His title clearly states "DIY "Spray Foam Insulation". It SHOULD say something like, DIY Foam board insulation. But, that foam board he used is good stuff. I built a shed out of coldroom storage panels. The stuff inside stays cool in the summer and warm in the winter.
