What is the highest R-value foam board?
Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation.
What’s the difference between spray foam and injection foam?
Spray foam can be either open or closed cell, while injection foam is a non-expanding open cell foam. While injection foam is an open cell, the reason it doesn’t expand is that you wouldn’t want it to apply pressure to the inside of the exterior wall.
Is it worth it to spray foam insulation?
