Fire and flame resistant
ETA™ Air Duct Systems are resistant to flame
spread from external or internal fire sources, and meet all
applicable fire safety standards for use in residential and
commercial buildings. ETA™ Air Duct Boards has classified as Class O
material in terms of flammability, smoke intensity, and smoke
toxicity.
Quiet noiseless operation
ETA™ Air Duct System has outstanding noise
absorbing characteristics and acoustical properties. This design
decreases the audibility of equipment noise, and eliminates
the sounds associated with the expansion and contraction of sheet
metal systems.
Efficient insulation
ETA™ Air Duct Board is manufactured from high
quality phenolic foam, the thermal conductivity can be as low as
0.022W/m.K, which out performs any traditional insulation materials
of the same thickness. The thermal performance inherent to the ETA™
Duct delivers warmed or cooled air at the desired temperatures,
ensures minimal energy loss, and reduces condensation problems.
Cost effective
ETA™ Air Duct Board System weighs about 1/3 of
lined sheet metal duct systems, which significantly reduces the
total load of any construction, especially in steel-structured
buildings. The light weight requires fewer supporting structures,
reducing any building’s overall weight and costs. Installation
becomes easier and quicker due to the less weight .
Low air Leakage
Air leakage from ETA™ Air Duct System is
extraordinarily low because of its exceptional air seal flanging
system.
