This reduces the temperature in your attic by up to 30 degrees.  When your attic is cooler, your house is cooler. In addition, radiant barrier roof deck sheeting is put on the same way conventional sheeting is, so there is no increase in labor costs to install it.  All of the wood used in this product comes from wood sourced through programs certified under the Sustainable Forestry Initiative^®. Finally, there is a 20-year transferable limited warranty on the product.
