Roof sandwich panel

Advantages:

• Excellent waterproof and drainage performance

  With a special corrugated design, it can efficiently guide rainwater and prevent water accumulation on the roof at the source. Combined with concealed nail connections and waterproof troughs, it can effectively avoid leakage problems at the joints.

• High fire safety level

  The core materials of mainstream products can reach B1 to A non-combustible standards. For example, the rock wool type has a fire resistance capacity of over 1000℃, which can effectively prevent the spread of fire and is suitable for various buildings with fire protection requirements.

• Outstanding insulation and soundproofing effect

  Relying on core materials such as rock wool and polyurethane, the thermal conductivity is as low as 0.022W/(m·K), which can significantly reduce building energy consumption; at the same time, it can weaken the impact of rainwater and external noise, and the sound insulation can reach 29-30dB.

• Efficient and hassle-free installation

  After factory prefabrication, it can be directly assembled on site without secondary processing. The daily installation efficiency can reach 600-800㎡, and the overall construction period can be shortened by more than 30%, significantly reducing labor and time costs.

• Excellent overall cost performance

  The board has a light weight, which can reduce the main load of the building. The long-term maintenance cost is low. Some categories have an outdoor service life of over 15 years and are suitable for various building scenarios such as factories, warehouses, and exhibition halls.
