Description

EcoFoil Perforated Radiant Barrier improves comfort and energy efficiency by reflecting radiant heat away from your living space. Built from a durable woven polyethylene core layered between two highly reflective metalized coatings, this material resists tearing and delivers long-lasting performance. The perforated design allows moisture vapor to pass through, preventing traps that can lead to attic condensation. With the ability to block up to 96% of radiant heat transfer, it helps reduce summer heat gain and retain warmth during colder months.

The evenly spaced micro-perforations—punched every 1/4"—make this product suitable for attic applications where vapor permeability is required. By reflecting heat away from the roof deck on hot days and reflecting heat back toward the living space in winter, it supports consistent indoor comfort across a wide range of climates.

Radiant Heat Control for Attics in Warm, Cold & Mixed Climates

This radiant barrier installs easily in both new and existing attics. In warmer regions, staple it to the underside of rafters or trusses for maximum heat reduction. In colder areas, laying it directly over attic floor insulation helps retain heat. For mixed climates or homes that see both extremes, installing it in both locations provides the strongest year-round benefit.

Durable, Tear-Resistant Perforated Barrier

The woven polyethylene core gives the material strength while maintaining flexibility for tight attic spaces. Its lightweight design is easy for DIYers and professionals to roll out, cut, and staple. The 1,000 sq. ft. roll offers ample coverage for typical attic upgrades or larger-scale projects.

Ecofoil just what my attic needed...

This is my first time installing radiant barrier in my attic. I found the material to be easy to work with - not too thin, not too thick. 4 ft. size works well to cover large attic as a one person job. Ecofoil arrived quickly and on time. Very happy with the purchase and the price was very competitive with other competing products. The website was very informative and easy to understand different products for different applications.

Definitely a difference.

July 2025. I'll start by saying the shipping was immediate, we received our order the next day which was wild! Full disclosure, we have not finished the entire attic because it has been too hot since it is July. We have 2 rows done, or about 8 feet high, and it has made an immediate difference already in the west and south facing rooms. I am excited to finish the whole attic and feel the full effect.
