• Certified by SCS Global Services to contain a minimum of 53% recycled glass content, 31% pre-consumer and 22% post-consumer.
• Certified to meet indoor air quality standards under the stringent GREENGUARD Indoor Air Quality Certification Program, and the GREENGUARD Gold Certification.*
*Duct liner up to and including 1" is GREENGUARD Gold Certified.
• Absorbs fan and air turbulence noise and reduces popping noises within sheet metal ducts.
• Outstanding thermal and acoustical performance.
• Bacterial and fungal growth resistant with an EPA registered biocide that protects the airstream surface from microbial growth.
Product Applications/ Installation
All portions of duct designated to receive QuietR® Textile Duct Liner shall be completely covered with duct liner, adhered to the sheet metal with 90% coverage of adhesive complying with ASTM C 916. Transverse joints shall be neatly butted and there shall be no interruptions or gaps. All transverse joints shall be edge-coated. Metal nosing on leading edges must be used where duct liner is preceded by unlined metal, and on all upstream edges when velocity exceeds 4,000 fpm (20.3 m/s). The black mat faced surface of the duct liner shall face the airstream.
QuietR® Textile Duct Liner shall also be secured with mechanical fasteners, either impact-driven or weld-secured, which shall compress the duct liner sufficiently to hold it firmly in place. For fastener spacing, see illustration.
Duct liner shall be cut to assure over-lapped and compressed longitudinal corner joints. For details, refer to NAIMA Publication AH124, Fibrous Glass Duct Liner Standard.
Minor damage and small tears may be repaired by coating with adhesive.
After installation, and prior to occupancy, blow out duct system to remove any cutting scraps or foreign material remaining in the duct.
Installing two layers of material to meet a specific liner thickness is not recommended. If the specification forces the use of multiple layers, the following steps must be taken:
1. Adhere bottom layer of duct liner to duct in normal manner.
2. Adhere top layer to bottom layer of liner using a minimum of 90% adhesive coverage.
3. Treat all leading edges with metal nosings to prevent separation of the two layers.
4. Use mechanical fasteners of the proper length for double layer.
