With the increasing awareness of environmental protection and the decreasing demand for energy consumption, building energy conservation is gradually receiving attention from people. The use of external wall insulation materials in Shandong is one of the important means of building energy conservation.

How does Shandong external wall insulation material achieve insulation effect? The main principle is to reduce the heat exchange between buildings and the outside world, that is, to reduce the heat absorbed and radiated by buildings, and to minimize the heat exchange with the outside world through insulation material layers. Therefore, the smaller the thermal conductivity coefficient of the insulation material, the better the insulation effect.

Common exterior wall insulation materials include polystyrene foam board, polyurethane foam board, extruded polystyrene foam board, etc.

Polystyrene foam board is a kind of thermal insulation material widely used at present, which has small thermal conductivity, stable thermal insulation performance and simple construction. The polyurethane foam board has better thermal insulation effect, but its cost is high, construction is complex, and its application range is relatively narrow. The extruded polystyrene foam board combines the advantages of both, with smaller thermal conductivity and wider use.

In addition to material selection, exterior wall insulation design is also crucial. For example, when selecting the thickness of the insulation layer, factors such as the influence of regional climate, the characteristics of building structures, and usage requirements should be taken into account. A too shallow insulation layer can cause a significant loss of heat, while a too thick insulation layer increases the weight and cost of the building.

In addition, strict control is required for the construction of external wall insulation materials in Shandong. Improper construction can lead to damage, leakage, and thermal bridging of materials, thereby affecting the insulation effect and even damaging building security.

In short, external wall insulation in Shandong is one of the important means of building energy conservation, providing tremendous assistance for energy conservation and emission reduction. Only by selecting insulation materials, developing scientific insulation design schemes, and strictly following construction standards can external wall insulation play a better role, reduce building energy consumption, and achieve sustainable development.
