The Insulation

After finalizing electrical, mechanical and plumbing rough-ins and inspections we were finally ready for insulation. I say "finally" because anyone who has built knows rough-ins can take a while and it doesn't feel like your seeing any significant progress! But there is a lot going on behind the scenes that is necessary to make this all come together. 

As mentioned previously the exterior insulation includes an R10 rigid foam board. Inside between the studs we chose a product called Spider Insulation, which is a spray applied fiberglass that can be installed in an open cavity like spray foam but is much less costly. Spray applied fiberglass preforms better than batt fiberglass and therefore results in higher R-values. 
​In the ceiling we used a Blown-in Blanket System also known as BIBS. This was the suggested product by our insulation contractor for the ceiling. They installed cardboard baffles and R60 fiberglass insulation. 

Between my husbands Masonry shop and my design offices we used spray foam insulation. Spray foam is a more costly but superior product, but the main reason for using this here was providing a vapour barrier as well as gas seal between the two sides.
