The durability of exterior wall insulation materials should comply with relevant regulations and design requirements. When constructing thermal insulation decorative integrated panels, everyone must abide by the above regulations. In this way, we can achieve twice the result with half the effort and achieve a higher aesthetic level at the speed at which our project can be completed. Due to the large permanent load of self-heavy tiles, it is difficult to remove all the air from the cement mortar bonding layer during construction of large tiles, which can easily form hollows. To address such problems, the exterior wall insulation and decorative integrated panels have low water absorption, and the single-layer panel does not exceed 12kg.

Exterior wall insulation material is to place the insulation material between the inner and outer wall pieces of the exterior wall. The inner and outer wall pieces can be made of concrete hollow blocks. It effectively protects the inner wall panels and insulation materials, and does not require high selection of insulation materials. The insulation board studies the unique internal structure of the system and maintains harmony with the external economic movement of the construction body. Supporting materials, special-shaped prefabricated components and supporting tools for the Class A fireproof insulation board system.

The construction steps of the exterior wall insulation project are very complicated, and each step is carried out very carefully to create a good living space for the users. If you want to find someone to do the insulation project. For buildings where the height of the exterior wall insulation material is less than 24m, the combustion performance of the exterior wall insulation board insulation material should not be lower than level B2. Among them, when B2 grade insulation materials are used, horizontal fireproof isolation belts should be set up for every three floors. Generally speaking, materials with thermal conductivity less than 0.23w/(m·k) are called thermal insulation materials, and materials with thermal conductivity less than 0.14w/(m·k) are called thermal insulation materials. Generally speaking, materials with thermal conductivity not greater than 0.05w/(m·k) are called insulating materials.

Exterior wall insulation materials All insulation materials have a porous structure and are prone to moisture absorption. When the moisture content is greater than 5 to 10 percent, after the material absorbs moisture, the moisture occupies part of the pore space that was originally filled with air, causing its effective thermal conductivity to increase significantly.
