I dig into one of the most flexible insulation materials on the market. Pound for Pound, could this material be that good? #inspection #residential #insulation #codeviolations

Good work!

Totally agree with everything you said. Other than the higher cost, using it over OSB instead of house wrap takes care of air sealing, vapor sealing, and thermal bridging issues.

Any reason why I couldn't use this on the inside? I was wanting to build a house with a pretty thick wall for the sake of lasting a long time. From the outside layer, going in: 1" stone cladding, concrete block (filled and with rebar), 2" foam board insulation, 2x6 wall with R-19. Would be in zone 6.

Another problem I have seen is if you don't have OSB or chip board siding, where is your torsional/sheer strength in your framing. I once wired a house & I asked the Builder about this, he said " the drywall will provede that". I do NOT agree!

My inspector wants drywall to cover all the foam even in the garage... important to mention
