**Phenolic Foam Pre-Insulated Panel for HVAC and Wall Heat Insulation

**Double Sides Aluminum Foil Composite Phenolic Foam Insulation Duct Panel

The double-sided aluminum foil composite phenolic foam insulation air duct board is composited through a continuous production line at one time. It adopts the sandwich structure principle. The middle layer is closed-cell phenolic foam, and the upper and lower cover layers are embossed aluminum foil on the surface. The aluminum foil pattern is treated with anti-corrosion coating, and the appearance is corrosion-resistant. At the same time, it has the advantages of environmental protection, light weight, convenient installation, time-saving and labor-saving, and high-efficiency heat preservation function. It can not only reduce energy consumption and pollution, but also ensure a clean environment. The air duct system thus made has great improvements in mechanical properties, such as bending resistance, compression resistance, brittleness, and processability, and meets the requirements of air conditioning and ventilation. It can be fully replaced in the air delivery system of air conditioning. Rubber-plastic composite air duct system of traditional air ducts, air valves, air outlets, static pressure boxes, and thermal insulation materials.

Product Advantages

** Good thermal insulation, which can greatly reduce the heat dissipation loss of the air conditioner;

** Anticorrosive and antibacterial coating aluminum foil is resistant to acid, alkali and salt spray;

** Light weight, can reduce the building load, and easy to install;

**The foam has excellent flame retardant properties, only carbonized under an open flame, no deformation;

**Good sound attenuation, no need to set up muffler cover and muffler elbow etc. The muffler accessories reduce costs.
