What are the types of commonly used insulation boards?
Porous insulation board
Porous heat insulation panel materials use their own pores for heat insulation, because the thermal conductivity of air in the pores is very low, such as fiber materials and foam materials are porous heat insulation panel insulation materials, such as XPS heat insulation panel is a very typical foam insulation material.
XPS extruded insulation board
XPS extruded insulation board is a rigid foamed plastic board, which is made of polystyrene resin plus other raw and auxiliary materials and polymers, mixed by heating, and then injected with catalyst. XPS board has a perfect closed cell honeycomb structure, which can effectively contain the infiltration of water molecules of water vapor, more effectively prevent heat conduction, and has a very low thermal conductivity, belonging to the category of high-efficiency insulation materials. Even when subjected to mechanical damage or in a rough surface state, it can effectively maintain low water absorption and rarely experience aging phenomenon
Heat reflective insulation board
Thermal reflective insulation board materials use materials with high reflection coefficients to reflect heat like mirrors that can reflect light. These materials with reflective heat characteristics are mostly metals, such as gold, silver, nickel, aluminum, and other metal materials, which have this heat reflection function.
Phenolic roof insulation board
Phenolic roof insulation panels have dual functions of fire prevention and insulation, can withstand high temperatures of 150 ° C, have a thermal conductivity of around 0.023, and have a service life of up to 30 years. They can make up for the shortcomings of materials such as polyurethane, polystyrene, and rock wool that cannot prevent fire, have poor insulation performance, and have a short lifespan. At the same time, phenolic board is lightweight and easy to construct, making it an excellent roof insulation material.

What are the advantages of phenolic roof insulation panels?
1) Excellent fire resistance
Phenolic foam is used as the thermal insulation layer, which is compounded with other materials for building thermal insulation. It can basically meet the fire protection standard of Class B1, fundamentally eliminating the possibility of external insulation fire. The temperature range is -190 ° C~+150 ° C.
2) Outstanding insulation and energy-saving effects
Phenolic insulation board has good insulation performance, with a thermal conductivity of about 0.023W/(m · k), which is far lower than the 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 has a light weight and a unit weight of generally 30-80Kg/m3. At the same time, phenolic insulation boards do not absorb water and are not afraid of rain.
4) Safety 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. When burned, it releases non-toxic smoke (under limited conditions, formaldehyde, carbon monoxide, etc. are released beyond the combustion limit).
5) Good dimensional stability
Phenolic insulation board has excellent dimensional stability and will not experience shrinkage, deformation, and other situations no matter what environment it is in.
