Perforated Radiant Barrier - 6,500 sq ft Package
EcoFoil Perforated Radiant Barrier uses reflective technology to increase the energy efficiency and comfort level of your home. A radiant barrier is made of a thin layer of woven polyethylene which is sandwiched between two layers of a highly reflective metalized coating. With the polyethylene core the product cannot be ripped or torn. It blocks 96% of radiant heat transfer, helping keep your home cooler in the summer and warmer in the winter.
With the word perforated in the product title, it's important to note this type of radiant barrier has tiny pin holes punched every 1/4" throughout the roll, making it the only product to be used in an attic. This is because Perforated Radiant Barrier allows moisture, at a molecular level, to pass through it. In a warm climate or Summer application, the best installation would be on the bottom of the rafters or trusses with staples. In a cold climate or Winter application, the best installation would be over the insulation on the attic floor, laid right on top. For dual climates and maximum efficiency it is recommended to be installed in both places. Perforated Radiant Barrier works by reflecting heat away from the attic during long, hot summer days and reflecting heat back into your living space during those cold winter nights.
Important - It is NOT RECOMMENDED to use any type of tape on the EcoFoil Perforated Radiant Barrier in your attic. The tape will block the perforations and allow condensation to form in these places!
