Perforated Radiant Barrier Foil - 4' x 125' (500 sq ft)

Also available in 1,000 sq ft rolls.

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 perforated foil 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. 

Perforated radiant barrier has tiny pin holes punched every 1/4" throughout the roll, making it the only product to be used as a radiant barrier for your attic. This is because Perforated Radiant Barrier allows moisture, at a molecular level, to pass through it. Perforated foil 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.

In a warm climate or Summer application, the best installation is on the bottom of the rafters or trusses with staples. In a cold climate or Winter application, the best installation is over the insulation on the attic floor, laid right on top. For dual climates and maximum efficiency it is recommended to install attic radiant barrier in both places. This 500 square foot roll is perfect for small spaces or to limit purchase of excess materials for your job. 

R-Value Of Radiant Barriers

Rather than rating by R-value, all radiant barrier products are measured by their reflective and emissive properties. EcoFoil perforated radiant barrier foil is 96% reflective and 4% emissive, meaning the product only allows 4% of radiant heat to pass through. For more information on R-values, see our How It Works page or contact a member of our service team via chat, calling (888) 349-3645, or using the form here.  

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.

Made of a thin layer of woven polyethylene, sandwiched between two layers of a highly reflective metalized coating. Tear-resistant. Tiny perforations allow passage of moisture and promote air flow.
