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.

Worked great for me, easy to install, does not tear

I had no problem installing this. It is light-weight yet does not easily tear. The perforations not only help against moisture problems, they also form a guide for cutting the foil in 90 or 45 degree angles. Most importantly, performance appears to be as good as claimed: We noticed a significant drop in attic temperature of about 10 degrees after installing this to the underside of the roof deck in our attic. We are located in hot San Diego east county.

Product arrived in good shape. Easy to handle, cut and staple. Feel like the unfinished attic where I attached it to the rafters isn’t as hot as before.

Wouldn’t pass up the radiant barrier

Great stuff
When attic was not radiant heat protected,
The temperature difference between out of doors and the bonus room could hit 25-30 degrees (yep, 80 outside, 110 upstairs)

Now it hovers between one to ten degrees, depending on time of day and the heat build up.

Our torture chamber has become a huge room in the house (working on wrapping insulation around the box of the room and it should be cool enough for AC). This is the second order that covers little missed spaces and will be new installed in our soon to be built backyard shed.
