The most prominent feature of exterior wall insulation phenolic board is insulation, non combustible, and resistance to high-temperature deformation. It overcomes the shortcomings of the original foamed plastic insulation material, such as flammability, smoke and deformation in case of heat, and retains the characteristics of the original foamed plastic insulation material, such as light weight and convenient construction.

1) Excellent fire resistance performance

Phenolic foam is used as the thermal insulation layer, which is compounded with other materials for building thermal insulation. The possibility of external insulation fire is fundamentally eliminated. The temperature range is -196 ℃~+120 ℃.

(2) Outstanding insulation and energy-saving effects

Phenolic insulation board has good insulation performance, with a thermal conductivity of about 0.020~0.025W/(m·k), which is far lower than commonly used inorganic and organic exterior wall insulation products in the market, and can achieve higher energy-saving effects.

(3) Lightweight and non absorbent

Phenolic insulation board is lightweight, with a unit weight generally ranging from 40-100Kg/m ³. At the same time, the surface of the phenolic insulation board can be composite with high-quality embossed aluminum foil, which is non absorbent, not afraid of rain, and corrosion-resistant and durable.

(4) Safety and environmental protection

Phenolic insulation board is an environmentally friendly and green product that does not irritate the skin or cause any harm to the human body. It is non-toxic and releases smoke when burned.

(5) Good dimensional stability

Phenolic insulation board has excellent dimensional stability and will not experience shrinkage, deformation, or other issues in any environment.

After the flame spraying experiment, it was found that the phenolic board surface does not burn, carbonizes at high temperatures, does not shrink, has no debris, has a low smoke density, and is environmentally friendly and safe. After five minutes of flame spraying, there is no obvious heating sensation on the back of the board, and the insulation performance is very good.
