Integrated insulation and decoration, as the external wall insulation and decoration of new buildings, can also be used for energy-saving and decorative renovation of old buildings. It can be applied to the construction, expansion, and renovation of industrial and civil buildings with concrete structures, steel structures, and masonry structures. The next step after polishing is to clean the debris. To prevent damage to the extruded board, it is best to use a fine bristled brush for cleaning. Reduced the erosion of the structure by harmful gases and substances from the outside, providing protection for the main structure.

There are two main reasons for the use of integrated insulation and decoration. One reason is that it can improve the surface roughness of the board, which is conducive to bonding and greatly improves the tensile bonding strength of the plastering mortar and adhesive. Extruded polystyrene board can effectively prevent water molecules from entering the board during normal use. This type of board is a relatively perfect insulation material, and its water absorption rate is important for the machine.

The integration of insulation and decoration can also demonstrate good non water absorption performance during use, making it a perfect insulation material. If the water absorption rate is high, it will also lead to a decrease in its performance. During use, it will enter a vacuum state, which better avoids air flow and heat dissipation, ensuring the durability and stability of its insulation performance. Secondly, when integrating insulation and decoration, it is important to choose insulation materials with low thermal conductivity. This not only meets the design requirements but also reduces transportation costs and occupies less space.
