Shandong external wall insulation material is a product that improves insulation effect by adding materials to the exterior facade of buildings. It can prevent the impact of external temperature and moisture on the interior of buildings, reduce energy waste, and lower energy bills. Common external wall insulation materials include polystyrene board, extruded polystyrene board, silicate board, etc.

Polystyrene board is a commonly used external wall insulation material in Shandong province. It has good insulation effect, is not easy to decompose, and does not absorb water. When using polystyrene board for insulation, attention should be paid to its flammability and compatibility with other building materials.

Extruded polystyrene board is also a commonly used insulation material, which has the characteristics of thermal insulation, moisture resistance, durability, and high strength and lightweight. However, its insulation performance is limited and requires thicker materials to achieve a certain insulation effect.

Silicate board is a relatively new type of insulation material, mainly made of mineral wool and glass fiber, easy to process, non combustible, and has good thermal insulation performance, suitable for various types of buildings.

In general, selecting suitable Shandong exterior wall insulation materials requires consideration of their thermal insulation performance, waterproof performance, durability, ease of processing, as well as corresponding installation, matching, fire prevention, and other issues. Reasonable insulation materials and their installation methods can not only improve the energy-saving effect of buildings, but also enhance their environmental performance and overall quality.
