Insulating your roof and attic space will help retain energy in your home often leading to cost savings and comfort improvement.

Insulation board for attic roof.

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. Better materials for attic roof insulation are rigid foam boards and spray foam insulation. Insulating in and around your roof attic space also prevents long term damage from moisture build up or ice damming which results from the warm air trying to escape through the apex of the roof but instead heating up the snow. Try a spray foam insulation kit to fill cavities gaps cracks expansion joints and other sources of air leaks.

It can act as an air and moisture barrier in addition to providing very high r value. Your board must leave at least inch gap between the board and the roof. It helps resist moisture that can lead to mold or mildew and provides increased sound and thermal insulation. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.

The superattic system creates a continuous air and insulation barrier directly beneath the attic roof with no thermal bridging to compromise energy performance. Install foam boards with the foil side facing you. Additionally insulation serves as a way to enhance sound proofing on the uppermost envelop of your house. It s often used over existing insulation in the attic where moisture control isn t needed.
