External wall insulation phenolic board

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.

Compared with phenolic panels, ordinary polyurethane panels do not have ideal fire resistance. They not only burn but also produce a large amount of toxic gases. To truly achieve the B1 level flame retardant index, polyurethane requires the addition of a large amount of flame retardants, which increases the cost of the product.

The fire resistance of phenolic materials can be said to come from genes. The closed cell foam structure is equivalent to small vacuums inside, blocking heat transmission. Truly achieve non burning and non shrinking when exposed to open flames.

In general, the thermal insulation effect of phenolic material is equivalent to that of polyurethane, and it is also a lightweight foam material. The fire resistance and comprehensive cost-effectiveness are higher than polyurethane, so many fields with high requirements for fire prevention and insulation will choose phenolic materials.

The exterior wall insulation phenolic board is CNC cut, and the product specifications can be directly cut and produced on the assembly line according to your needs. The maximum width can reach 1.2 meters, the length can reach 3 meters, and the thickness can be customized for any thickness between 2 centimeters and 23 centimeters.

The selection of surface composite materials for exterior wall insulation phenolic panels can also be prefabricated according to needs. Depending on the application field, we can composite mortar mesh cloth, aluminum foil, needle punched cloth, and silica calcium fireproof board.

We support the development of special sizes, interfaces, and fields. Our company's production process department has a professional team that provides customized services based on drawings and samples. As long as you can provide application scenarios, we can provide solutions. We have the ability to produce samples in three days, mass production in seven days, and multiple production lines simultaneously, with high production capacity and worry free supply.

At present, phenolic exterior wall insulation phenolic panels have been widely used in building exterior walls, roofs, renovation of old houses, fire isolation belts, suspended ceiling insulation, etc.
