External wall insulation materials are a very important part of construction projects. They can effectively reduce the temperature and heat transfer of the building wall surface and improve the energy-saving performance of the building. At present, common external wall insulation materials include polystyrene board, rock wool board, extruded board, polyurethane board, etc. Various materials have their own characteristics and scope of application, so as to meet the insulation needs of different buildings.

Polystyrene board is an insulation material with polystyrene as the main raw material. It has certain insulation performance and convenient construction characteristics. It is widely used in the insulation of new and old buildings. Rock wool board is made of mineral wool as the main raw material. It has good fire resistance and thermal insulation performance. It is widely used in the insulation of high-rise buildings, public buildings and other fields.

Extruded board and polyurethane board are relatively less used external wall insulation materials. Extruded board refers to a plastic sheet extruded in an extruder. It has good thermal insulation performance and corrosion resistance, but the price is also relatively expensive. Polyurethane board is an insulation material with polyurethane as the main raw material. It has good thermal insulation performance and sound insulation performance. It is widely used in the insulation of industrial buildings, commercial buildings and other fields.

In addition to the performance of the insulation material itself, the construction quality of the insulation material also directly affects its insulation effect. Therefore, when choosing insulation materials, it is necessary to choose regular manufacturers and professional construction teams to ensure the quality and construction quality of exterior wall insulation materials.

In short, exterior wall insulation materials are an indispensable part of construction projects. Choosing appropriate insulation materials and professional construction teams can provide effective insulation effects for buildings, reduce energy consumption, reduce environmental pollution, and improve the sustainability of buildings.
