Rigid foam insulation
We are doing rigid foam on 4500 sq. ft. of exterior walls at 4″ thick and 4500 sq. ft. of roof at 8″ thick in a REMOTE application.
We are attempting to find the best value for our exterior foam insulation.
So far the best value ($26 for 2″x4’x8′) we could find was NeoPro TK. Seems to be a new product so not a lot of info on this “revolutionary” new material. http://www.permarproducts.com/insulsheathing.html
Our previous first choice was Foamular 250 http://www.foamular.com/foam/products/foamular-250.aspx, until we started getting quotes ($34 for 2″x4’8′).
PolyISO is out at this point due to it’s fluctuating R Values and our need for some below grade applications.
Can anyone recommend any other products?
