What Is Radiant OSB Used For? The goal of a foil-backed OSB is to cool the air within the top layer of insulation in the attic or wall by emitting the radiant heat absorbed through the roof or exterior walls, which reduces the Delta-T and lessens the overall energy use in a building. What is
What Is A Radiant Barrier For An Attic? Radiant barriers are installed in homes — usually in attics — primarily to reduce summer heat gain and reduce cooling costs. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. They don’t, however, reduce heat conduction like thermal insulation materials.
Where Do You Put Reflective Insulation? Install unfaced mass insulation between rafters ensuring a minimum of 1′′ ventilation space between the mass insulation and the underside of the roof decking. … Unroll and staple reflective insulation to the under side of the rafters. Seal all seams with aluminum foil tape. Which way do you install
