So, the temperature difference may be around 20F (10C). Soreness in the nose and throat can result when fibers are inhaled. Many above-ground ducts are manufactured with a fiberglass liner to provide insulation and sound reduction. 0000023443 00000 n
An insulation like an elastomeric foam is non-particulating and releases no fibers into the air. Liners also help insulate the ducts, keeping your residence more comfortable and energy efficient. The 4 common types of duct insulations are as follow: Normally, insulations are put on the external surface of ducts to prevent condensation and energy loss. Fiberglass continues to be used in duct installation today but is now required to be produced with strict erosion restriction guidelines. If the damage is localized, new internal internal insulation can be installed within the ducting. Over time, seals in joints in above ground metal ductwork become loose and cause leaks that lead to energy loss, increased energy bills and contamination of indoor air. Meeting all of these performance goals cost efficiently in a competitive environment can often be a challenge. 0000048657 00000 n

To simply state, if acoustical performance is the main project requirement, like in a school or medical facility for example, then specifiers should consider selecting duct liner. These environmental changes take its toll on the duct liner, breaking down its primary seal. As a result, these particles are locked down and prevented from entering your indoor air. If you notice any of the issues above, you may have a leak in your air ducts. Often, the AHU supply air temperature is around 57F (14C) and the room temperature is around 75F (24C).
