Insulation Board For Attic Roof

It helps resist moisture that can lead to mold or mildew and provides increased sound and thermal insulation.

Insulation board for attic roof.

It can act as an air and moisture barrier in addition to providing very high r value. Try a spray foam insulation kit to fill cavities gaps cracks expansion joints and other sources of air leaks. The superattic system creates a continuous air and insulation barrier directly beneath the attic roof with no thermal bridging to compromise energy performance. Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces.

Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. Your board must leave at least inch gap between the board and the roof. Technically known as spray polyurethane foam or spf spray foam is most commonly applied in the space between attic rafters. 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.

Install foam boards with the foil side facing you. Insulating your roof and attic space will help retain energy in your home often leading to cost savings and comfort improvement. To create an airtight seal use foil tape. Use furring strips nailed into the sides of the rafters so that you have something to fasten the board to.

Better materials for attic roof insulation are rigid foam boards and spray foam insulation.
