Two-layer polyethylene bubble core bonded to two layers of highly reflective metallized aluminum polyester film. This radiant barrier is designed to reduce radiant heat gain and improve overall insulation performance. Key benefits - High radiant heat reflectivity: Reflects up to 97% of radiant temperature, helping to keep spaces cooler in hot weather and reducing heating/cooling loads year round. - Tested performance: Meets ASTM E84 test standards with a Class 1 / A fire-rating radiant barrier. - Durable and stable: Does not compress, collapse, or disintegrate over time; maintains its insulating properties under typical loads. - Easy to install: Staples are held securely without tearing; easier to install than fiberglass insulation; cuts cleanly with a utility knife or scissors. - Mess-free and patient-friendly: No loose fibers, reducing mess and skin/eye irritation during handling. - Versatile installation: Designed to be installed in place of staples, nails, or adhesives; simple on-site cutting to fit irregular spaces. Attributes and material - Construction: Two-layer polyethylene bubble core paired with two layers of reflective metallized aluminum polyester film. - Moisture resistance: Not affected by moisture; helps prevent condensation in conditioned and unconditioned spaces. - Pest resistance: Does not attract or support insects or rodents. - Maintenance: No ongoing maintenance required; lightweight and easy to handle. Applications and use scenarios - Attic and roof line insulation: Install under the roof deck or over existing insulation to reflect radiant heat away from living spaces. - Crawl spaces and basements: Use to improve thermal performance and reduce moisture-related issues in restrained, low-clearance areas. - Ducts and industrial spaces: Ideal for insulating duct runs or larger commercial/industrial applications where a durable, puncture-resistant radiant barrier is beneficial. Installation notes - Cutting: Easily cut to fit with a utility knife or scissors. - Fastening: Can be installed in place of staples, nails, or adhesives; no specialized tools required. - Handling: Light in weight and free of fiberglass-type fibers, enabling a clean installation process. Energy impact - By reducing radiant heat transfer, this barrier can contribute to lower year-round energy costs and improved comfort in a variety of building envelopes.
