Attic Baffles For Spray Foam
Rafter Baffles to Insulate: Rafter baffles are an excellent way to keep insulation in place. They can be used to make space between rafters, and help keep air from escaping. They are available in various sizes and can easily be customized to fit any rafter width. They can be used to double the coverage of eaves.
SmartBaffle is sized to fit 16" and 24” center rafters. The SmartBaffle can also accommodate different rafter widths. SmartBaffle is compatible with spray foam and loose-fill fiberglass. It is built for tough, unbreakable handling. SmartBaffle has a lifetime durability and is made of non-collapsing plastic. To get the best 'R’ and U' values (winter and summer), insulation should be placed in the remaining rafter area. This baffle is more efficient than any competitor, allowing for 2" of airflow in between the rafter areas. You can create a SmartBaffle that is wider or narrower to accommodate uneven rafter space. Also, the various attachment methods are described in the enclosed box.
After you have secured them, you can either place the blankets or batts on the attic floor. Note: Blowing insulation may require an additional block in order to prevent it from blowing into the soffit. This is easily accomplished by placing a piece or rigid foam board along the outer edge.
