Traditional wall plastering uses surface mortar and alkali resistant mesh cloth, which have low waterproof performance. The thin plastering system is prone to cracking, water seepage, and moisture entering the insulation layer, which not only reduces the insulation effect of the insulation material but also causes phenomena such as hollowing and cracking. The distance between high-voltage wires and the construction site in the construction environment of external wall insulation materials should comply with relevant regulations, and corresponding protective facilities should be provided. There is a continuous and uniform surface layer and a closed cell honeycomb structure, with interconnected walls of consistent thickness and no gaps between the boreholes.
The external wall insulation material is usually applied after plastering the wall, and then the entire wall is covered with insulation material, commonly known as full insulation, which is not very distinctive. Flower insulation, on the other hand, is used to apply insulation material to some areas, and the rest are treated with self insulation through masonry.
Exterior wall insulation materials are suitable for buildings with special insulation requirements, such as cold storage, and can also be used for buildings with exterior wall decorative materials made of bricks or stones. In addition, its unique closed porosity and high gas diffusion resistance give it excellent long-term insulation performance. Most high-rise buildings have strict requirements for the fire resistance of insulation materials. Once flammable materials are used as insulation materials and catch fire, the consequences can be unimaginable.
The external wall insulation material can be easily cut with ordinary tools for workers to install and then plaster the wall. Thinner walls also mean less space is required for on-site material storage, which is another major benefit for building projects with extremely limited space. After tightening the mesh cloth, stick it onto the bottom plastering mortar, and use a trowel to press the mesh cloth into the mortar surface from the middle to the periphery, paying attention to leveling and compaction. Do not wrinkle the mesh cloth, and do not press it too deeply.
