Duct liner: CertainTeed
CertainTeed says it is strengthening its line of high-performance HVAC insulation products with the addition of ToughGard® R Rotary Duct Liner. Combining the trusted thermal, acoustical, and moisture control performance of the ToughGard liner airstream surface with a sustainable fiberglass matt, ToughGard R is ideal for helping to ensure high indoor environmental quality and occupant comfort.??
The duct liner now features a sustainable plant-based binder that contains no added formaldehyde, acrylics, or dyes, and is Greenguard Gold Certified for low chemical emissions. Its main raw material is sand, an inert, abundant and naturally renewing resource, and it includes a high percentage of recycled glass. ??
In addition to contributing to LEED® and other green building standards, company officials report the new fiberglass formulation makes the product easier to work with and install. Officials also said the company's field-proven airstream surface and mat makes hand or machine cutting easy, resulting in clean, crisp edges. The black surface is also water repellent, highly cleanable, and contains an EPA-registered antimicrobial agent to ward off potential for mold and microbial growth on the liner surface.
ToughGard R absorbs equipment and air rush noise over a broad spectrum of sound by trapping and dissipating it within the glass fiber matrix, contributing to better interior acoustics. It also provides thermal-insulating properties and lower HVAC operating costs by reducing energy consumption. Its thermal properties help control condensation, which helps improve indoor air quality by reducing unwanted moisture.??
