To protect the wall cavity and insulation from these problems, a high-performance barrier that is impermeable to water vapor is the best solution.
DELTA®-REFLEX is completely impermeable to water vapor. This highly effective barrier helps to prevent wetting and damage of thermal insulation, protecting the building enclosure for many years to come.
- 4-ply membrane
- Highly reflective and corrosion-resistant aluminum layer laminated between a transparent polyester film and a grid-reinforced polyethylene film
- Class E, EN 13501-1
Features- Completely impermeable to water vapor, which helps to prevent wetting and damage of thermal insulation
- If installed as a radiant barrier, the aluminum layer enhances the effectiveness of thermal insulation by up to 10%. Another benefit is 50% heat reflectance, allowing for a more energy-efficient structure
- Shields off up to 99% of hazardous electromagnetic radiation
- Can be installed explicitly as a radiant barrier. There simply needs to be a 1” space between DELTA®-REFLEX and the drywall
- Extraordinary tensile strength prevents tearing during installation
- Extreme flexibility allows for quick installation, even in difficult places
