Acoustically effective

Fibrous glass duct liner absorbs fan and air turbulence noise, reduces noises caused by expansion, contraction and vibration typical of sheet metal ducts.

Thermally efficient

Factory controlled insulation thickness assures that specified R-values will be met when installed in accordance with manufacturers' instructions.

Mat-faced or coated air stream surface

Fibrous glass duct liner minimizes air friction loss while enabling the insulation to withstand easily the duct cleaning process when NAIMA recommendations are followed.

Factory-applied edge coating

This coating saves fabricators the time and cost involved in coating transverse joints to meet industry requirements.

Bacteria and fungus resistant

Fibrous glass duct liners resist fungal and bacterial growth when subjected to microbial attack as described in ASTM C 1338, required for airstream surfaces per ASHRAE 62.1- 2001; and, additionally, ASTM G 21-96 (fungus test) and G 22-96 (bacteria test), required by ASTM C 1071.

Code Compliance

Fibrous glass duct liners meet the physical property requirements of ASTM C 1071 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.
