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!

Radiant barrier works

I’ve used radiant barrier in several buildings. The results are fantastic. The best I’ve found come from eco foil. The eco foil team ships fast and also is very helpful. They have several products and they all perform well. You can’t go wrong by choosing ecofoil.

I specify this product for all preservation/renovation jobs

We began experimenting with this product about seven years ago on our own 1850 log cabin. As an archaeologist/architectural historian we continually run into unique structural challenges and try to find adaptive ways to preserve the authenticity of a building but give it the livability we all need. Don't forget the perforated foil on interior stone walls--notoriously hard to insulate and provide vapor barrier. Also huge attic spaces as in a barn adaptation--so easy to work with. We are currently retrofitting a third structure here at our farm and are thrilled with the results. We'll be back and I will keep encouraging others to use this insulative foil.
