Duct liner is used primarily as acoustical liner in HVAC sheet metal ducts to absorb unwanted crosstalk, equipment and air rush noise. It also helps improve the energy-efficiency of the system by reducing heat gain or loss. Plus, duct liner helps minimize moisture problems due to condensation.
Similar to ToughGard 2 Textile Duct Liner, ToughGard R is composed of rotary-type glass fibers. It also has the same durable air stream surface and moisture protection.
FEATURES AND BENEFITS
- Quiet Operation: ToughGard duct liner helps absorb equipment and air rush noises over a broad spectrum of sound. Noise is trapped and dissipated within the glass fiber matrix.
- Thermal Protection: All products offer excellent thermal-insulating properties and lower HVAC operating costs by reducing energy consumption. This saves natural resources and reduces emissions into the atmosphere.
- Water Repellency: The thermal properties of duct liner help control condensation, which helps improve indoor air quality by reducing unwanted moisture.
- Low Emitting: Certified by the GREENGUARD® Environmental Institute.
- Low Air Resistance: The smooth ToughGard air stream surface offers low air resistance to deliver efficient HVAC system operation.
- Resists Microbial Growth: The air stream surface contains an EPA registered antimicrobial agent in order to reduce the potential of microbial growth that may affect this product. The antimicrobial properties are intended to only protect this product.
- Durable: The strength and resiliency of the ToughGard surface provides outstanding resistance against puncturing, tearing and other damage during fabrication, installation, and periodic system maintenance.
- Long-lasting and Non-corrosive: Inert fiber glass will not deteriorate or provide sustenance for vermin or rodents, and it will not corrode the sheet metal it insulates.
- Cleanability: The smoothness and durability of all ToughGard duct liner products means an extremely cleanable surface during the life of the duct system. The surface of each product can be easily and effectively cleaned with industry-recognized duct cleaning equipment and procedures as outlined in the North American Insulation Manufacturers Association (NAIMA) Duct Cleaning Guide. Proper design, filtration, maintenance and operation of the HVAC system will reduce the need for cleaning.
