Condensation control

When installed thickness recommendations are followed, fibrous glass duct wrap insulation installed over sealed sheet metal ducts reduces the likelihood of condensation occurring on the vapor retarder facing, and of moisture damage to ceilings and other interior finishes.

Enhanced comfort control

By reducing heat loss or gain through duct walls, conditioned air reaches occupied spaces at temperatures close to design conditions. Central air equipment may therefore be operated at reduced levels, saving energy.

Flexible, easily installed

Fibrous glass duct wrap insulation is easily cut to proper fit. For ease of application, a staple flap is provided by the manufacturers.

Code compliance

Fibrous glass duct wraps meet the physical property requirements of ASTM C 1290 as well as meeting the fire safety requirements of NFPA 90A and 90B including limited combustibility. They also comply with all widely used model codes including ICC, BOCA, CABO, ICBO, and SBCCI.
