Duct liner
CertainTeed Corp., Valley Forge, Pa. |
The ToughGard duct liner with enhanced
surface repels moisture. But unlike reflective, continuous film coatings
used on other duct liners, the "breathable" enhanced surface coating preserves
the sound-dampening performance of the duct liner by allowing sound waves
to pass through the open-cell structure and into the sound-absorbing glass
fiber mat. The surface will help alleviate concerns about moisture that
may enter a duct system due to improperly sealed duct joints or poorly installed
and maintained HVAC systems.

Continuous cleaning
Steril-Aire Inc., Cerritos, Calif.
|
 X-Mount
UVC Emitters are designed to provide continuous, non-chemical cleaning of
ducts and other HVAC surfaces. The ultraviolet devices come in five tube
lengths (16, 20, 24, 30, and 36 in.) to fit most ductwork applications.
These devices provide a non-polluting and permanent alternative for keeping
surfaces free of mold and microbial contamination. The emitters are readily
installed by making a 1-in. penetration into the duct wall and running the
light across the width of the duct. Only the lamp or tube penetrates into
the ductwork, while the power supply remains external. The UVC energy will
rapidly "cook off" mold and other microbes.
