1. Foundation treatment: The insulation layer construction shall be carried out on the basis of stable wall foundation, smooth surface and no obvious cracks. If there are cracks in the wall, they need to be repaired first.
2. Determine the construction surface: determine the construction surface of the insulation board according to the requirements of plane layout. Generally can be divided into vertical plane, horizontal plane and inclined plane.
3. Installation of insulation board: according to the determined construction surface, cut the insulation board into appropriate sizes according to specifications and stick it with special glue. Pay attention to avoid repeatedly using scissors to cut, so as not to affect the insulation effect of the wall due to rough section.
4. Joint filling treatment: After the insulation board is installed, joint filling treatment is required. It mainly includes the filling of the periphery, joints and holes. Generally, polyester foam flame retardant caulking agent is selected as the filling material, and the caulking material should be closely butted with the joint of insulation board to fill evenly and harmoniously.
5. Surface treatment: There are many methods to treat the surface of insulation board, such as brushing and pasting decorative materials. Can be selected according to the design requirements.
6. Sealing treatment: After the insulation board construction is completed, it needs to be sealed. It mainly includes treating the joints of the upper and lower parts of the construction surface and the joints between the insulation board and the doors and windows.
In a word, the construction method of insulation board wall involves many steps, and each step needs to be operated in strict accordance with the specifications to ensure the construction quality, and finally achieve the effects of heat preservation, heat insulation and waterproof.
