The flexibility of spray foam insulation lets you improve energy efficiency even if your roof has air vents to the outside. By applying spray foam insulation on the attic floor, you can avoid common problems that traditional insulation types present:
- A ‘stack effect’ – occurs from the lack of air sealing by traditional insulations, which allows heated air to escape through the ceiling into the attic. Air on floors below 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.
Spray foam insulatoin helps avoid these types of problems to maintain a comfortable indoor air temperature and avoid energy losses.
