External wall insulation material is a material that can be attached to the surface of the building's external wall and play a role in thermal insulation. It can not only improve the thermal insulation performance of the building, but also reduce energy consumption and reduce indoor energy expenses. There are many types of external wall insulation materials on the market. Here are some common materials.

First of all, polystyrene board is a relatively common external wall insulation material. It has excellent thermal insulation and compressive properties, which can prevent the generation of cold and hot bridge effects. At the same time, polystyrene board also has good sound insulation performance, which can provide a quiet and suitable indoor environment. In addition, polystyrene board is easy to construct and low in cost, and is one of the materials of choice for external wall insulation of many buildings.

Secondly, rock wool board is also a commonly used external wall insulation material. Its main component is molten basalt or lignite and other raw materials that are melted into fibers at high temperature and then processed by special processes. Rock wool board has good sound absorption and thermal insulation properties, which can prevent the generation of cold and hot bridge effects and reduce indoor temperature fluctuations. In addition, rock wool board also has good fire resistance, which can improve the security performance of buildings.

Then, the exterior wall insulation exterior wall mortar is a material specially used for exterior wall insulation. It is made of cement, quartz sand, lightweight aggregate, exterior wall insulation fiber and exterior wall fine powder and other materials mixed in a certain proportion. The exterior wall insulation mortar has good frost resistance and weather resistance, which can prevent the cracking and falling of the exterior wall paint. At the same time, the exterior wall insulation mortar also has good adhesion, which can protect the exterior wall and improve the overall effect of the building.

In summary, exterior wall insulation materials play an important role in improving the thermal insulation performance of buildings. Polystyrene board, rock wool board and exterior wall insulation mortar are all common exterior wall insulation materials, and they each have their own advantages and disadvantages. When choosing exterior wall insulation materials, it is necessary to consider comprehensively according to the actual situation, budget and needs of the building. I hope this article can help you understand exterior wall insulation materials.
