Moreover, external wall insulation is also a more reasonable energy-saving practice for buildings, with higher energy efficiency. For the problems faced by external wall insulation, other insulation methods such as external wall internal insulation can be used, and efforts can also be made to improve the quality of external wall insulation projects by controlling the quality of insulation materials and standardizing construction operations. The non removable insulation formwork is a permanent external formwork, with concrete poured on the inner side and a lightweight mortar leveling layer and polymer anti cracking mortar plastering layer on the outer side. The non removable insulation formwork is firmly connected to the concrete through connectors to form a cavity free composite insulation system, abbreviated as HFC non removable insulation formwork system.

The exterior walls are subject to severe weather conditions such as storms and scorching sun for a long time. If the products and processes used are slightly lacking, it is easy to encounter quality problems. For ordinary exterior wall decoration, if the bottom is completely removed and rebuilt, the amount of work will be huge. If it is directly covered on the old wall, it may crack due to adhesion delamination.

The tensile strength of the insulation layer used in the exterior wall insulation decorative panel varies depending on the insulation material used. Generally speaking, insulation materials with high bulk density have better tensile strength than those with low volumetric weight. The production of integrated insulation and decoration panels is completed through factory and automated production lines. The multi nozzle automated assembly line spray painting machine effectively eliminates color differences and ensures the high-end decorative effect of the product.

The traditional thin plastering system has multiple and complex processes, which increases the uncertainty of construction. The insulation layer is prone to cracking, causing coating cracking and peeling, affecting the aesthetics and actual insulation effect. The insulation board adhesive is uneven, the adhesive strength is poor, and the final decorative effect is greatly reduced. Severe insulation layer detachment may occur, posing a safety hazard. The exterior wall insulation decorative panel is lightweight, high in strength, and has fast construction speed. It has excellent insulation and decorative performance, and is much lighter than other curtain wall panels of the same area. Impact resistance: No cracks, peeling or penetration. It not only reduces the burden on buildings, but also greatly lowers safety hazards.

Brush the surface of the wall with cement mortar, with a flatness of ≤ 4 gate plates/2.0m. The internal and external corners should be vertical and horizontal, and the plastering surface should meet the quality acceptance requirements of ordinary plastering in ordinary plastering. The walls shall not have defects such as dirt, dust, grease, hollows, cracks, and delamination. Higher requirements have been put forward for the external insulation system of the exterior wall. Due to the influence of solar radiation and environmental temperature changes, the crack resistant protective layer on the insulation layer only needs 3-20mm, and the insulation data has a large thermal resistance. Therefore, under the same heating conditions, the temperature change rate of the crack resistant insulation layer is faster than that without the insulation layer.
