5mm 1/4 Double Poly-Air Insulation: Positioned between two sheets of highly reflective radiant barrier aluminum. This robust yet lightweight material is easy to cut and install, allowing for stapling or nailing to any surface without undermining the insulation's effectiveness.
WATER AND MOLD RESISTANT: WILL NOT OXIDIZE LIKE PURE ALUMINUM DOES / Not Effected by humidity and moisture. 100% Waterproof. Can be used in outdoor and indoor applications.
ASTM Class 1 Class A Fire Rated / Meets all USA and Intl Fire Codes (even Australia)
SOUND REDUCTION: Great Sound Deadener. Effectively reduces sound travel creating a soundproof environment (closed cell foam core)
EFFECTIVE THERMAL RADIANT BARRIER: Reflects 99.97% of radiant heat transfer with a thermal resistance R Value of 24 (Building Envelope). Prevents heat from escaping during colder seasons and does not allow heat to enter during the summer months.
