Interior and exterior extruded panel is a new material used for interior and exterior decoration and insulation engineering of buildings, which has excellent performance and wide application prospects. In this paper, the definition, characteristics, classification, construction methods and other aspects of extruded board are introduced in detail to help readers better understand and use the material.

First, the definition of internal and external extruded panels

Internal and external extruded board, also known as extruded insulation board, is a plate-like material made of polystyrene as raw material by extrusion process. The material has the characteristics of light weight, heat preservation, sound insulation, fire resistance, water resistance, pressure resistance, etc., and is widely used in the heat preservation and decoration of the interior and exterior walls of buildings.

Second, the characteristics of internal and external extruded panels

1. Good thermal insulation performance: internal and external extruded panels have excellent thermal insulation performance, which can effectively reduce the energy consumption of buildings and improve indoor comfort.

2. Lightweight: The interior and exterior extruded board is a lightweight material, light weight, easy to handle and construction.

3. Good sound insulation effect: the internal and external extruded panels have good sound insulation effect, which can effectively reduce the spread of indoor and outdoor noise and improve the environmental quality of the building.

4. Excellent fire performance: the interior and exterior extruded board has good fire performance, which can effectively improve the fire rating of the building.

5. Good water resistance: the inner and outer wall extruded board has good water resistance, is not easy to absorb moisture and deformation, and can effectively prevent the moisture phenomenon of the building.

6. Strong compressive performance: the inner and outer wall extruded board has good compressive performance and is not easy to deformation and rupture.

Third, the classification of internal and external extruded panels

According to the different materials, the internal and external wall extrusion board can be divided into polystyrene extrusion board, polyurethane extrusion board and rock wool extrusion board and other types. Among them, polystyrene extruded board is the most common one at present, but also the most widely used one.

Fourth, the construction method of internal and external extruded panels

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. In the future, the internal and external extruded panels will be further developed, and the thermal insulation performance and construction efficiency will be continuously improved to meet the needs of the construction industry.

In SUMMARY:

As a new type of building material, extruded board has excellent thermal insulation performance, light quality, good sound insulation effect, good water resistance, strong fire resistance and other characteristics, and is widely used in building interior and exterior insulation and decoration projects. Through scientific construction methods and classification details, the internal and external extruded panels can better play their role and adapt to the development needs of the future construction industry. In the future, the application prospects of internal and external extruded panels will be broader and will play a greater role in the construction industry.
