External wall polyurethane board

External wall polyurethane boardIt is a high-performance building material mainly used for external wall insulation and waterproofing. It has the following main characteristics and advantages:

1. Excellent insulation performance: The thermal conductivity of polyurethane board is very low, usually between 0.017-0.024 W/m · K, which makes it low in thermal conductivity among all insulation materials and has good insulation effect.

2. Good waterproof performance: Polyurethane board has a high closed cell rate (not less than 90%), belongs to hydrophobic materials, will not increase thermal conductivity due to moisture absorption, and has excellent waterproof performance.

3. Fire resistance: Polyurethane boards have the characteristics of being difficult to ignite and self extinguishing after adding flame retardants. It does not produce harmful gases at high temperatures and can effectively prevent the spread of flames.

4. Structural stability and durability: Polyurethane board has a high-strength interconnected wall closed cell structure, excellent impermeability, and a service life of over 30 years, suitable for various environmental conditions.

5. Convenient construction: Polyurethane board is easy to construct, and can be sprayed or poured. It has fast construction speed, high efficiency, and is suitable for various complex building surfaces.

6. Environmental performance: Polyurethane board has stable chemical properties, does not pollute the environment, and only carbonizes without dripping during combustion, effectively blocking air from entering and preventing the spread of fire.

Application scenarios
External wall polyurethane boardWidely used in external insulation systems for industrial and civil buildings, especially in situations where efficient insulation and waterproofing are required. Its excellent performance makes it an ideal choice for external wall insulation and waterproofing.
