Rigid Liner Board with ToughGard Facing is a high-quality acoustical and thermal board-type insulation used primarily for lining the interior of HVAC sheet metal ducts and plenums to absorb unwanted crosstalk, equipment and air rush noise. This product performs in most types of heating and cooling systems operating at velocities up to 6,000 fpm (30.5 m/s) and temperatures to 250?F (121?C).

Rigid Liner Board with ToughGard Facing improves energy efficiency by reducing heat gain or loss. The product can be precision cut using both manual and automatic cutting equipment, and is durable and easy to clean.

Composed of glass fibers firmly bonded together with a yellow or black thermosetting resin into a rigid board-type insulation. 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 protect only this product.

Features

• 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: GREENGUARD Gold Certified.
• 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 fiberglass 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.

Design Considerations

• “Butter” all raw exposed edges.
• High in-duct air turbulence areas may require special procedures (perforated inner metal liner, etc.).
• Metal nosings should be securely installed over transversely oriented liner edges facing air stream at fan discharge and at any interval of lined duct preceded by unlined duct.
