Ductz+™ is a flexible fire resistant blanket system used for 2-hour rated duct insulation. It is tested per ASTM E2336, UL 2221 and ULC S144.
The blanket is fully encapsulated and having a nominal thickness of 1-1/2 inches (38 mm) and a density of 6 pcf (96 kg/m3). The core material is a high temperature body low bio-persistence fiber that utilizes a unique spinning technology to create a special fiber with superior thermal and mechanical properties. This fiber is made from a blend of calcium, silica and magnesium and can be exposed to temperatures up to 2192°F (1200°C). The core insulation blanket is completely encapsulated in an aluminum foil fiberglass reinforced scrim covering. This scrim provides additional handling strength as well as protection from grease, moisture absorption and tearing.
