In today's construction industry, the use of exterior wall insulation materials is becoming more and more common. These materials not only help improve the energy efficiency of buildings, but also provide a comfortable indoor environment for residents. This article will introduce several commonly used exterior wall insulation materials to help you better understand this field.

1. Polystyrene foam board

Polystyrene foam board is a lightweight and efficient exterior wall insulation material. It is made of expanded polystyrene particles through heating, pressurization, catalyst injection and other processes, and has excellent thermal insulation and sound insulation effects. This board is usually used for exterior wall insulation, which can effectively reduce heat transfer and keep the indoor temperature stable.

2. Rock wool board

Rock wool board is an insulation material made of natural rock as the main raw material, which has multiple functions such as fire prevention, heat insulation and sound insulation. It has high durability and can resist wind and rain erosion, making it an ideal choice for exterior wall insulation. The thickness of the rock wool board can be customized according to the insulation needs of the building to meet different insulation effects.

3. Phenolic foam board

Phenolic foam board is a new type of insulation material with excellent thermal insulation and fire resistance. It is a mixture of phenolic resin and additives such as foaming agent, and has the characteristics of non-flammable, smokeless and environmentally friendly. Phenolic foam board has good compressive and tensile strength and can adapt to the load requirements of buildings.

4. Perlite insulation board

Perlite insulation board is an insulation material made of perlite as raw material, which has the characteristics of light weight, heat insulation and sound insulation. Perlite is a mineral with high heat capacity that can absorb and release heat, thereby playing a role in insulation. Perlite insulation board has good weather resistance and durability and can adapt to the influence of outdoor environment.

5. Glue powder polystyrene particle exterior wall insulation system

This system is composed of glue powder, polystyrene particle insulation material and plastering mortar, and has good insulation performance and crack resistance. This system can be used for exterior wall insulation of various buildings, especially for the renovation of old houses and energy-saving buildings. When using this system, you need to pay attention to construction details to ensure construction quality.

6. Wire Mesh Sandwich Panel

Wire mesh sandwich panel is a sandwich panel made of metal frame, polystyrene or other insulation materials. This board has excellent insulation performance and durability, and can adapt to the influence of outdoor environment. In addition, it has good decorative properties and can be customized as needed.

In short, all of the above exterior wall insulation materials have their own advantages and scope of application. When choosing suitable insulation materials, factors such as the structure of the building, insulation requirements, and budget need to be considered. At the same time, it is also necessary to carry out construction according to construction specifications to ensure construction quality.

In addition, attention should also be paid to the environmental protection performance and safety of the materials. When choosing exterior wall insulation materials, products that meet relevant national standards should be selected to ensure the energy-saving effect of the building and the safety of the residents. Afterwards, for new exterior wall insulation materials, sufficient experiments and tests are required to ensure their effectiveness and safety in practical applications.
