Now, the exterior walls of some new buildings need to be insulated. The insulation effect of the exterior wall is indeed very good, not only can it provide sound insulation, but it can also adapt to the general situation of warm winter and cool summer indoors. Personal insulation effect is helpful for our families. But how to implement external wall insulation for building a house? The plastering of the exterior wall has been completed and dried, with a curing time of 5-7 days. The flatness and verticality of the exterior wall after plastering shall meet the medium plastering standard (4mm/2m). There will be no cracks, dents or polishing.

Plastering and reinforcing mesh: Apply polymer cement mortar evenly on the entire surface of the insulation board, and then spread the steel mesh with plastering. The thickness of the plaster layer should be 3mm to 5mm, using a two-way mortar method, and it should be uniform. Alkali resistant mesh should be placed horizontally and tightly pressed; There shall be no hollowing, folding, warping or exposure; All should be buried in the plaster layer and not exposed. Alkali resistant fiberglass mesh should not be placed in the rain. Alkali resistant glass fiber mesh should be cut as much as possible in the warp and weft directions. The alkali resistant fiberglass mesh should overlap horizontally by 100 millimeters and vertically by 100 millimeters.

It has good compatibility with cement mortar and concrete, reliable adhesion, and similar expansion coefficient. Like traditional high-temperature fired ceramic building materials, it will not crack, deform, or shrink under thermal expansion and cold contraction. After double-sided application of inorganic interface agents, the tensile bonding strength of cement mortar can reach 0.2mpa or higher.

Polystyrene insulation decorative integrated board is mainly used for building wall and roof insulation, composite board insulation, etc. It is divided into foam EPS board (benzene board) and continuous extruded XPS board (extruded board). The production process of polystyrene insulation decorative integrated board is extrusion molding. The extruded polystyrene board is a short XPS board, and is mainly composed of polystyrene resin or its copolymer, and a small amount of additives are added to extrude hard foam products with closed cell structure by heating.

The gel material is very light, with heat insulation and fire prevention functions. The main material is nano alumina aerogel. The most important characteristics are high temperature resistance, low thermal conductivity, and the ability to absorb noise and vibration. It is an essential high-efficiency insulation material in the fields of metallurgy, chemical engineering, national defense, and aerospace. The price of polystyrene insulation decorative board is higher than that of polystyrene board, so the insulation of extruded board has been applied in many aspects. The insulation board and its height should be minimized according to standard dimensions.
