Did you know that by adding a radiant barrier to a roofing assembly with an air gap you can ELIMINATE 97% of radiant heat gain into any structure? The average roof temperature will drop 20˚F to 40˚F just by doing this one thing! This is true for homes, barns, sheds, garages, warehouses, etc. 

We do not recommend using pressure treated wood in direct contact with the ALUMINUM side of the RoofingFoil™ products.

Our single-sided perforated RoofingFoil™ is a good option for roofing without a tear off, since you'll be keeping the original tar paper (waterproofing) layer. For an economical underlayment option on new roofing, you can use our single-sided solid RoofingFoil™.
