External wall insulation is an important part of building energy conservation, and plays an important role in ensuring building energy efficiency and improving project quality. In recent years, cracking, hollowing, peeling and other quality incidents of external wall insulation systems in various places have occurred frequently, which has attracted social attention. The matching of external wall insulation systems, insulation materials and actual construction processes and methods ensures that the performance of external wall insulation systems and insulation materials is reliable and the construction process is feasible, thereby ensuring the quality of external wall insulation projects.

External wall insulation extruded board has two functions of decoration and insulation. Only one purchase and one installation are needed, and the decoration and insulation of the facade can be completed. And mesh cloth, anchor bolts and rock wool special interface agents are used to ensure the durability and safety performance of the insulation system. For the thin plastering system, this indicator of external wall insulation extruded board will directly affect the use of the board. The strength of EPS board is low, and the shear strength is also low. The damage of the board may not be on the bonding surface, but directly in the middle of the board.

An important part of building energy conservation is to pay attention to the raw materials of the products. Generally, polyurethane insulation boards are foamed from black and white materials. The quality of these raw materials is basically the same in appearance, so you must be careful when purchasing and ask the merchant about the raw materials of the products.

The manufacturer of extruded board said that before using extruded board construction, the corresponding layout should be prepared to avoid materials, etc. The use of polyurethane insulation board in the exterior wall insulation system can effectively avoid the loose cracking of the glue powder polystyrene particle insulation mortar, and the shrinkage cracking of inorganic insulation mortars such as closed-cell perlite and vitrified microspheres.
