Features and benefits

Single-component system

Thermal and acoustical insulation plus essentially air-tight performance are provided with one product installed by a single contractor.

Factory-controlled insulation thickness

Factory-controlled insulation thickness assures that specified R-values are met.

Acoustically efficient

Fibrous glass insulation absorbs fan and air turbulence noise, reduces popping noises caused by expansion, contraction, and vibration.

Light weight

Fibrous glass duct components are easy to fabricate, transport, and install. Compared with metal ductwork, they impose less load on the building structure.

Essentially air-tight

Closures made with UL 181A listed pressure-sensitive tape, heat-activated tape, or glass fabric and mastic, save energy by virtually eliminating air leakage.

Code compliance

Fibrous glass duct systems qualify under UL 181 as Class 1 Air Ducts, 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.

Backed by industry standards

Fabrication and installation standards published by NAIMA and SMACNA help the contractor to provide reliable, long-term system performance.
