Description

EcoFoil’s Solid Radiant Barrier Foil enhances energy efficiency by reflecting radiant heat away from your living or work space. Built with a reinforced polyethylene core and metalized reflective surfaces on both sides, this material offers excellent durability while remaining easy to handle on the job. It blocks up to 96% of radiant heat, helping keep interiors cooler during hot months and retaining warmth in colder seasons. When all seams are sealed with reflective tape, it also serves as an effective vapor barrier to limit moisture migration. Suitable for walls, roofs, floors, and crawl spaces, it installs quickly by stapling perpendicular to framing and taping every seam to maintain continuous protection.

High-Performance Radiant Heat Control

This solid radiant barrier is engineered to reduce radiant heat transfer in both new construction and retrofit applications. By reflecting heat away from the building envelope, it provides a measurable improvement in temperature stability and overall comfort—especially in attics, metal structures, and areas with significant solar exposure.

Durable, Lightweight Barrier for Walls, Roofs & Crawl Spaces

The polyethylene-reinforced structure resists tearing and holds up during installation, even in challenging spaces. Its lightweight nature makes it easy to maneuver in tight areas, while the dual reflective coatings provide long-lasting performance. Once installed and taped, the vapor-resistant layer helps defend against moisture issues that can develop in confined or unconditioned spaces.

Key Features

  • Reflects 96% of radiant heat: Helps maintain more stable indoor temperatures year-round.
  • Durable polyethylene core: Reinforced construction resists tearing during installation.
  • Effective vapor barrier: When seams are taped, it helps prevent moisture intrusion.
  • Lightweight and easy to work with: Installs quickly on walls, roofs, floors, and crawl spaces.
  • Improves energy efficiency: Reduces radiant heat gain and loss for better thermal performance.
  • Simple installation: Staple perpendicular to framing and seal every seam with reflective tape.
  • Versatile application: Works in residential, agricultural, and light commercial settings.
