Polyurethane PU Insulated Sandwich Panel Roof Sheet

Polyurethane insulation board is a highly efficient insulation material. With its unique properties, it is widely used in many fields such as construction, cold chain transportation, industrial plants, etc. 

1.Low thermal conductivity: The thermal conductivity of polyurethane insulation board is about 0.018-0.024W/(m·k), which is the lowest thermal conductivity among all insulation materials, so it has good insulation performance.
2.Moisture-proof and waterproof performance: The closed-pore rate of rigid polyurethane is above 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water.
3.Fireproof and flame retardant: After adding flame retardant, polyurethane is a flame-retardant self-extinguishing material. The softening point can reach above 250 degrees Celsius. It will only decompose at higher temperatures and will not produce harmful gases when burned.
4.Strong deformation resistance: Polyurethane board has excellent compressive strength and deformation resistance, is not easy to crack, and has a stable and safe finish.
5.Good sound insulation effect: Polyurethane insulation board also has good sound insulation effect, which can effectively reduce noise.
6. Convenient construction: polyurethane insulation board is easy to cut and install, with fast construction speed, saving time and labor costs.
7.Environmental protection and pollution-free: polyurethane insulation board will not pollute the environment during production and use, and is an environmentally friendly material.
8.Economical and affordable: Although the initial investment of polyurethane insulation board is high, due to its advantages of good insulation, fire resistance, and convenient construction, it can save a lot of energy and maintenance costs in the long term, so it has high economic value.

In summary, polyurethane insulation board is an insulation material with many excellent properties. It is not only energy-saving and environmentally friendly, but also can improve the safety and comfort of buildings. It is a new material worthy of promotion and application.
