The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.
Radiant barrier roof sheathing reviews.
The osb techshield radiant barrier osb is engineered to improve energy efficiency.
Installed in over 2 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.
