The construction wall of the extruded board can form a vacuum layer to prevent air flow and heat dissipation, thereby better ensuring the thermal insulation and stability of the product. Secondly, this product also has high-strength compressive resistance. This product has excellent compressive strength and can bring a lot of convenience to people when used. In order to extend the service life of the insulation board, it is still necessary to pay attention to its maintenance in daily life. Only by maintaining it well can its service life be extended and its own performance be demonstrated.

The texture of the extruded board is relatively light and very convenient to use. It is easy to cut and transport when used, and it is not easy to break and easy to install. During the use process, if it is used in the sun for a long time, there will be no aging phenomenon, and it has certain aging resistance when used, and there will be no damage.

The extruded board requires that the wall must be dry and cannot be constructed on rainy days. The base wall must be thoroughly cleaned of floating dust, stains, release agents, hollows, protrusions and weathering products on the surface that affect the bonding strength. When choosing, you need to choose a board with sufficient strength to ensure that it can withstand external forces. The insulation material should be easy to construct and easy to operate.
