Spray Foam Insulation & Attic Floors
If your home’s roof has air vents to the outside, the flexibility of spray foam can still allow you to improve energy efficiency by applying the insulation on the attic floor.
Using a traditional insulation such as fibrerglass or cellulose, common problems can include:
- A ‘stack effect’ – which occurs due to lack of air sealing by these traditional insulations, allowing heated air escape through the ceiling into the attic. Air on lower levels is replaced by air drawn in from the outside.
- Ice Damming – which occurs due to warm, moist interior air coming into contact with the cold roof during Winter, where moisture condenses and freezes
