After the insulation construction and repair of extruded polystyrene board, the next step is to consider the construction of the decorative layer. In order to ensure the overall effect of the exterior wall, we suggest that the owner re coat the entire wall according to the division and segmentation of the wall. To verify the reliability of waterproofing for doors and windows.

The construction and repair of extruded polystyrene boards for outdoor insulation or metal or plastic wrapping should be used in areas prone to mechanical wear and tear. Attention should be paid to the sealing of seams and joints. If necessary, adhesive sealing strips should be added, and the overlap of the layers should not be less than 100mm. It has good weather resistance, color retention, and stain resistance, with a hardness comparable to granite, providing effective protection for buildings. Decorate the exterior walls of buildings with strict and scientific construction standards to create a granite like decorative effect.

Appropriate building materials and corresponding technologies can be used to design and construct building facades that maintain thermal comfort. Proper insulation of walls can maintain a balanced and stable indoor temperature, reduce the energy consumption of heating, air conditioning, and other equipment, and achieve energy-saving effects. The external wall internal insulation system is mainly made of XPS extruded polystyrene board, which is fixed on the inner surface of the external wall by adhesive and nail methods, protected by plaster mortar, and reinforced with alkali resistant fiberglass coated mesh cloth.

The construction and repair project of extruded polystyrene board adopts a combination of adhesive and bolt fixation methods (different from adhesive and external steel wire mesh fixation methods), making this system more reliable. External wall insulation does not take up the interior decoration period, and can be immediately constructed after the main construction, making it suitable for insulation of high-rise buildings. When pasting extruded boards, the flatness adjustment should be made by tapping with a rubber hammer, and the adjustment should not be made by shifting up and down or left and right to avoid the adhesive overflowing into the gaps between the boards due to the misalignment of the extruded boards, forming a cold bridge and causing significant negative effects.
