 Application advantages of thermal insulation wall energy saving system


Among the insulation and energy-saving forms of building exterior structure, there are mainly composite external wall thermal insulation energy-saving system and single thermal insulation wall energy-saving system. The composite external wall thermal insulation energy-saving system is provided with an insulation layer on the outer side of the outer wall (most of the insulation materials used are polystyrene foam board products, but also extruded polystyrene board, foamed polyurethane, etc.), and are decorated outside the insulation layer. The most simple layer is the coating. If reliable construction measures are taken, the tiles or other heavy-duty decorative materials (such as splitting blocks or even hanging stone or metal curtain walls) can be attached. The advantage of this type of insulation is that the insulation performance is good and light. The combination of thermal insulation material and heavy-duty wall material is both insulated and insulated, and has a wide range of applications, and is suitable for various structural forms and walls.
(1) The application of a single thermal insulation wall system in a wall is mainly used as a non-load-bearing infill wall. The most reasonable is the outer wall used for the frame structure, which can be used as an outer wall in a multi-storey building with a cross-wall load-bearing. The application in the seismic zone should be cautious, and the amount used in the short-limb shear wall system is not too large, because the shear wall part also needs other insulation forms.

(2) According to people's application habits, it is considered that the plastering of the aerated concrete wall is easy to crack. In fact, in many areas, this problem has been solved, such as plastering the inner surface, using plaster plaster, and the outer surface is made of dry mortar or interface agent compatible with the aerated concrete material. Some companies supply matching mortars while producing products, which is very helpful for ensuring quality. This supply model is worth promoting.

(3) When developing a single thermal insulation wall energy-saving system, reasonable thermal performance indicators should be proposed according to the material characteristics of the product. For example, in cold and cold areas, if the aerated concrete product is used purely as a composite insulation material for walls or roofing, the density and thermal conductivity of the product should be reduced as much as possible. Another point is that the aerated concrete products have good thermal insulation performance and large thermal resistance, but the thermal inertia index and the heat storage coefficient are poor, and the delay time is short. In some hot summer and cold winter areas, both insulation and heat insulation should be considered. Propose thermal performance indicators for products that meet the climate characteristics of the region. Although there is no problem of wall insulation in winter heating in hot areas, for areas where energy consumption of air-conditioning and refrigeration is consumed all year round, reasonable structural indicators should be formulated for the problem of “cooling” and insulation of walls. When developing a single insulation wall energy-saving system, technical and economic indicators such as material properties and thermal performance indicators and wall thickness of the products to be used should be comprehensively considered according to regional climatic conditions, national energy-saving standards for the region, and combined with material properties.
