1. Surface treatment: Before construction, the building wall should be cleaned and treated to ensure that the surface is smooth and clean.

2. Hanging net sealing: A grid is set around the building to fix the extruded board and increase stability.

3. Painting of construction glue: Paint construction glue on the wall to increase the adhesion between the inner and outer wall extruded panels and the wall.

4. Installation of the extruded board: Install the extruded board horizontally and vertically on the wall, keeping the spacing evenly.

5. Add rubber strips: Seal the joints of the extruded board with rubber strips to increase the tightness of the connection.

6. Plastering layer construction: plastering layer construction is carried out on the extruded board to increase the beauty of the building.

5. Application fields of extruded panels for internal and external walls

Extruded panels are widely used in the fields of external insulation, internal insulation, roof insulation, cold storage insulation and sound insulation of buildings. Its excellent performance and convenient construction methods make the interior and exterior extruded panels an indispensable material in the construction industry.

6, the future development trend of internal and external extruded panels

With the improvement of building energy consumption and environmental protection requirements, the application prospect of extruded panels in interior and exterior walls is very broad.
