Cut energy usage and cost with the Reach Barrier 3139 Reflective Air2 Attic Ladder Insulation Kit. It prevents cool air or heat from escaping the home at attic-access locations. The folding ladder, which provides access to the attic, can cause tremendous cooling and heat loss because there is only a thin piece of plywood between the living space and excessive heat or cold in the attic. Thermal imaging has shown hot air temperatures of 110 degrees F or more around ladder access points. This insulation kit utilizes Reach Reflective Air2, which is comprised of two layers of sealed air laminated between two layers of durable reflective polyethylene. This gives Reflective Air2 the ability to retain its air longer and provides excellent insulation and sound reduction. Reflective Air2 meets all ASTM standards and complies with building code. Installing a radiant barrier may be the lowest-cost improvement that can produce the greatest overall reduction in energy usage and expense.
