Mtkl phenolic foam pre-insulated ducting panel compounded with aluminum foil is of high strength, which takes phenolic foam as the core material with reinforcing the aluminum foil on both sides. It's a kind of noncombustible material which gives off no smoke and no poisonous gas when exposing to fire. Its bending strength reaches over 1mpa and the thermal conductivity index 0.020w/mk. The phenolic foam can be fabricated into all kinds of rectangular(bended) ducts by cutting and adhesive connecting, then can be assembled into the air ducts of different specifications by using the fire-proof flange and adhesive. It's widely used for the ventilation systems of central air conditioning units in hotels, apartments, hospitals, office buildings and other deluxe buildings.

The feature of mtkl phenolic foam air duct system:

Lower heat conductivity, higher thermal efficiency

Low density, light weight

Foamed with cfc free materials, environment protective

Hermetic seal ensures little air leakage

With aluminum foil reinforced on both sides, it's corrosion protective, hygeian, and has a beautiful appearance.

Foamed with closed-cell structure, it's water-proof and sound-insulated.

Easy making, rapid installing and convenient maintenance cost.

No protruding flange on the connections, it can save a lot of building

Six advantages of mtkl phenolic foam air ducts:

Mtkl phenolic foam air ducts for central air-conditioning has six advantages compared with the traditional air duct products on the market. The advantages are as follows:
1. Low thermal conductivity (0.02w/ m. K) ensures excellent insulation property.
2. Light weight for transportation and handling duct work eliminates having to use heavy duty anchors and supports.
3. Long service life.
4. Temperature capabilities ( -250 to 150)
5. Easy to install which helps on cost savings.
6. Uniform in appearance of the installed duct work.
