If the base material of the exterior wall insulation decorative integrated board changes, it may cause the insulation layer to fall off in pieces. Generally speaking, even if it falls off, the protective mesh cloth wrapped on the outside is not easy to fall off all at once. It may be because of the strong wind that the mesh cloth is also torn. After use, the warmth of the building can be guaranteed. At the same time, because the board has high strength and good stability, it is not easy to have quality problems during use. It is a very good building material.

Before the construction of the exterior wall insulation decorative integrated board, the participating construction unit organizes the design, construction, supervision, insulation system manufacturer or system supplier and other units to conduct a special review of the construction drawing design documents, and clearly defines the key parts and key nodes involving safety and important use functions. The foaming structure of the extruded polystyrene insulation board (XPS) is closely connected, and there is no gap between the walls, so the impact strength is very high, and it will not change even if it is fired for a long time.

There are two situations in which the base material of the exterior wall insulation decorative integrated board changes, one is the concrete wall, and the other is the brick wall. The concrete wall does not need to do the cement mortar procedure, and the brick masonry needs to do cement mortar. Before pasting, the surface flatness of the insulation layer should be tested according to the thickness of the insulation layer (usually 10 mm), and the pasting work can be carried out only after ensuring that the wall surface flatness meets the requirements. Everyone knows that the exterior wall insulation decoration integrated board is a material that is currently used more in building exterior wall decoration. It can enjoy multiple functions with one assembly and one purchase, combining the dual protection of insulation and decoration.
