Also available in 500 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 1,000 square foot roll is perfect for a DIY or large-scale project. 

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.

Materials:

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.

Wrinkled roll

I purchased two small rolls they were fine. I ordered a large roll, and when they were wound on the cardboard tube, they got three creases in it, which will not go away does not harm anything but the appearance doesn’t look good which I don’t like.

    Frequently Asked Questions

    What is the difference between Radiant Barrier Foil and Reflective Bubble Insulation?

    Radiant Barrier Foil provides the same heat-reflecting properties as Single / Double Bubble Reflective Insulation. The difference is there are no bubble layers in Radiant Barrier Foil. The bubbles featured in our Bubble products provide a thermal break between air on both sides of the material, and prevent formation of frost and condensation inside and outside your building. Without the bubble layer(s), you're at greater risk of condensation forming inside and/or outside of your structure. Learn more here.

    If you'd like to reflect radiant heat while also controlling condensation, choose Reflective Bubble Insulation.

    Should I choose Solid or Perforated Radiant Barrier?

    This will depend on your application. In ventilated areas such as attics, it's important to allow air flow in order to reduce the chances of moisture and mold from forming. In such applications, choose Perforated Radiant Barrier

    Outside of attics, we typically recommend Solid Radiant Radiant Barrier Foil. For questions on your specific application, feel free to call us at 888.349.3645, send us a chat, or contact us electronically.

    Should I use tape in my attic?

    No. Please do not use tape when installing Perforated Radiant Barrier in your attic. Tape could trap moisture in your attic which could lead to mold and mildew. Tape is only recommended with Solid Radiant Barrier Foil and Reflective Bubble Insulation, in situations where you want a vapor barrier. For more information, feel free to call us at 888.349.3645, send us a chat, or contact us electronically.

    How does Radiant Barrier Work?

    Radiant barriers reflect radiant heat back towards its source, keeping interior spaces warmer in the winter and cooler in the summer. Radiant heat barriers can be used in a variety of applications and climates, providing more comfort to indoor spaces, while saving you money on energy bills year-round. You can learn more about how Radiant Barriers work here.

    How do I install Radiant Barrier?

    Installation methods will vary, depending on your application. If your structure has exposed studs, the material can be stapled with a staple gun. If you have nothing to staple the product to, choose a spray adhesive like Spray-Lock Multi-Purpose Eco-Friendly Spray Adhesive.

    General tips:

    • With any Radiant Barrier application, there must be air space on at least one side of the material. Learn more about air space requirements here.
    • Never sandwich a radiant barrier between two surfaces without allowing for an air space, otherwise the heat will conduct through the material and will become ineffective. The only exception is Under Concrete Slab applications—due to the nature of these applications, an air space is often not an option.
    • Unless you're insulating an attic, Reflective Insulation Tape is recommended to seal the seams. Never use tape with Perforated Radiant Barrier.
