Insulation board for attic roof.

Technically known as spray polyurethane foam or spf spray foam is most commonly applied in the space between attic rafters. It helps resist moisture that can lead to mold or mildew and provides increased sound and thermal insulation. The superattic system utilizes proprietary silverglo rigid foam insulation panels to fully seal and insulate the attic directly beneath the roof rafters and directly inside the gable ends. It s often used over existing insulation in the attic where moisture control isn t needed.

To create an airtight seal use foil tape. Better materials for attic roof insulation are rigid foam boards and spray foam insulation. Your board must leave at least inch gap between the board and the roof. Try a spray foam insulation kit to fill cavities gaps cracks expansion joints and other sources of air leaks.
