Phenolic foam and special jacketing film
Tin duct + rubber foam insulation + Tin jacket
Phenolic foam and special jacketing film (new method)
0. UL-723 listed, perfect vapor barrier layer, CUI (Corrosion under insulation) blocking function
Fire Safety Semi-incombustible material does not generate toxic gas in case of fire and does not burn
Compared to the existing tin duct, it weighs about 1/4, so it is easy to transport and install, and there is no need for additional insulation. Prevention of safety accidents
It has the advantage of reducing noise by preventing resonance inside the duct.
The leakage of the duct is zero and energy is saved because rain or moisture cannot enter from the outside.
The optimal material for STS ducts such as hospitals, clean rooms, pharmaceutical companies, food factories, swimming pools, kitchen exhaust, septic tank exhaust, etc.
It is cheaper than the tin jacket construction cost, and the construction period can be shortened by more than 50%
Tin duct + rubber foam insulation + Tin jacket (existing method)
Most widely used in a universal way
The rubber foam insulation has a thermal conductivity of 0.035W/mK, which is much higher than that of phenolic foam, so the thickness of the insulation must be 25T or more.
In the event of a fire, poisonous gas is generated, causing personal injury.
Leakage of the duct occurs by 3-5%, and rain or moisture penetrates from the outside, which lowers the performance of the insulation and consumes excessive energy.
Difficult to repair if crushed
