Finishing attic insulation plan

1324 Views 5 Replies 3 Participants Last post by  HomeSealed
Here is my insulation plan
use Demilec Heatlok Soy 200 7.4 R value at 1 inch
spray 5.5 in thick for room and 2 in thick for the rest of attic roof.
I am also thinking about adding fiberglass under the 2in foam section of attic.

Here is what the space is looking like.

What do you think?

The attic does not have any vents or soffit, So I am thinking I should keep it that way and do a unvented Attics.

What do you think? Would I have to add soffits and vents if I don't condition this space?
I calculated 4,100 bf of insulation

Any Idea on what this will cost for CC spray foam?
