In the current era where building safety is crucial, Yanghu Board Industry's polyurethane sandwich panels, with their excellent B1 fire rating, have become a reliable fire barrier in the construction industry, safeguarding the fire safety of various types of buildings.

Accurate compliance with standards and authoritative norms

According to the strict standard GB 8624-2012 "Classification of Combustion Performance of Building Materials and Products", Yanghu Plate Industry's polyurethane sandwich panels have been tested by professional institutions and all indicators accurately meet the B1 level requirements, including flame-retardant materials

Grade. In the combustion performance test, the flame propagation rate is effectively controlled, and the flame propagation range within the specified time is extremely small. After leaving the fire, it can quickly self extinguish without continuous combustion, reducing the risk of fire from the source and laying a solid foundation for building safety.

Excellent performance, responding to fire challenges

In practical application scenarios, the B1 fire resistance advantage of Yanghu Board Industry's polyurethane sandwich panels is fully demonstrated. Once a fire occurs, the polyurethane edge sealing layer will quickly carbonize at high temperatures, forming a dense carbonized layer. This carbonized layer is like a sturdy armor, which not only effectively prevents flames from further spreading inward and penetrating deep into the sandwich panel, but also blocks the rapid transfer of heat, slowing down the damage of fire to the overall structure of the panel.

Diversified advantages, balancing safety and practicality

Compared to ordinary fire-resistant panels, the B1 fire-resistant rating of Yanghu Board Industry's polyurethane sandwich panels gives it many significant advantages. In the process of architectural design and construction, B1 level fire resistance provides designers with broader creative space to meet diverse architectural design needs. Whether it is complex commercial building exteriors or office spaces that pursue flexible spatial layout, they can be easily adapted without sacrificing design aesthetics due to fire restrictions. At the same time, from a long-term usage perspective, B1 fire rating means higher safety and reliability, reducing building maintenance costs and potential economic losses caused by fire hazards. It is an ideal choice for building projects to pursue a balance between safety and economic value, and to build a strong safety defense line for the entire life cycle of the building.
