With the development of technology and the improvement of people's living standards, keeping warm in winter has become an indispensable part of our lives. As an important component of building insulation, the installation and protection of exterior wall insulation materials are particularly important. This article will provide a detailed introduction to the installation and protective measures of winter exterior wall insulation materials, helping everyone better cope with the cold winter.

1、 Selection of external wall insulation materials

1. EPS board: EPS board is a kind of rigid foam plastic with closed cell structure, which is made of polystyrene as raw material through foaming treatment. It has the advantages of light weight, low thermal conductivity, low water absorption, and high compressive strength, and is currently one of the widely used exterior wall insulation materials.

2. XPS board: XPS board is a rigid foam plastic with closed cell structure, which is made from polystyrene through extrusion molding process. It has the advantages of low thermal conductivity, low water absorption, high compressive strength, and good dimensional stability, and is suitable for external wall insulation of various buildings.

3. Polyurethane board: polyurethane board is a rigid foam plastic with closed cell structure, which is made of polyurethane as raw material through foaming treatment. It has the advantages of low thermal conductivity, low water absorption, high compressive strength, and good weather resistance, and is suitable for external wall insulation of buildings.

2、 Installation of external wall insulation materials

1. Grassroots treatment: Before installing exterior wall insulation materials, the base layer should be treated first to ensure that it is clean, flat, free of oil stains and hollows. For areas with cracks, it is necessary to repair them with cement mortar.

2. Bullet line positioning: According to the design requirements, mark the installation position line of the insulation material on the wall to ensure that the insulation material is installed neatly and aesthetically.

3. Paste and fix: Paste and fix the insulation material according to the position of the snap line positioning. When pasting, it is necessary to ensure that the insulation material is in close contact with the base layer to ensure the insulation effect.

4. Grinding and leveling: After the insulation material is pasted and fixed, the surface of the insulation material should be polished with sandpaper to make it more closely in contact with the base layer and improve the insulation effect.

5. Construction of protective layer: Apply a protective layer on the surface of the insulation material, such as anti cracking mortar or anti cracking coating, to prevent the insulation material from being affected by the external environment and extend its service life.
