Thank you so much for this video amazing, all your videos have been so helpful. I wish I could hire your company. I want to ask, I think it be easier for me to use fiberglass bat insulation. I plan to go up there and do it myself the same way you showed me how to do. But can you tell me and everyone else that may read this. How big of a difference is there in the job and air sealing difference in Cellulose vs bat insulation? I would think not much if a person uses the can of spray foam and seals all the gaps as that seems to be what is most important. If a person does that step and does a bat insulation vs Cellulose is there really a big difference or would it still work great with what I guess would be R-30 Bat insulation?
Hey Kevdog thanks for the shout out! For your questions: 1) For air sealing qualities there isn't a shortcut, it has to be done with foam and every penetration sealed like you see in the video. No insulation type other than spray foam will accomplish this. 2) Batt fiberglass can work well in attics, but likely not as well as blown cellulose (with batts it's hard to avoid having some gaps). Best practice would be: a) Air seal the attic floor b) Install your first layer of fiberglass between the floor joists. c) Build your hatch wall and lattice for the storage pad. d) Install another layer in between the lattice joists. e) Attach your plywood to the lattice/ storage pad floor f) Install another layer of batts in the eaves/ outer roof slope areas so that they are about even with where the roof rafters rise up and clear the attic floor joists. g) Install another layer of batts running perpendicular to the attic floor. This gets you coverage over top of the floor joists and helps account for any gaps in your first layer. You want to fit pieces into the eave areas first (in between the roof rafters) because you won't be able to get another layer into that space just by running the batts perpendicularly -- unless you have a very steep roof). Hope this helps and if you have other questions let me know! Andy

Great idea. Do you have affiliates in Eastern PA (Bucks County)?
Thank you! Unfortunately I do not.
