Polyurethane sandwich decorative panels, as building exterior wall insulation materials, have incomparable advantages over other wall panels. In recent years, they have been considered as building energy-saving new technology materials that need to be vigorously promoted. There are many materials with thermal insulation effect for external walls, such as polystyrene foam board, rock wool board, various composite thermal insulation slurry boards, etc., but these traditional thermal insulation materials have their own advantages in terms of thermal conductivity, thermal insulation effect, durability, strength, etc. Its advantages and disadvantages cannot guarantee the integrity of its functions.
The newly developed exterior wall panel ensures the integrity of its functions and overcomes the shortcomings of traditional insulation panels. First of all, it consists of three parts: the surface is a nano-anti-fouling color-coated steel plate treated with a special layer, the middle layer is a high-density rigid polyurethane foam that has been fire-resistant, and the bottom layer is an aluminum foil anti-corrosion protective layer that plays a role in heat preservation and moisture resistance . The sandwich panel itself has the characteristics of thermal insulation, waterproof and flame retardant, light shock resistance, sound insulation and noise reduction, convenient construction, beautiful and durable, green and environmental protection, and at the same time, it is not limited by the seasonal environment because of its simple and practical panel assembly method. It is very convenient and quick to use. This innovative external wall thermal insulation decorative panel stands out from the crowd of thermal insulation panels, highlighting its absolute advantages.
Metal carved exterior wall panels have a wide range of adaptability. They are not only suitable for exterior wall insulation decoration of newly built frame structures, brick-concrete structures, steel structures, light-weight houses, etc., but also can be used for energy-saving renovation of existing buildings and indoor and outdoor decoration. decoration etc.
