The construction site of the external wall insulation material adopts the construction process of the external wall insulation system (except for the insulation decorative composite board) which basically turns the construction direction of the external wall insulation project to the construction of the internal insulation of the external wall. The external insulation is almost completely prohibited except for the insulation decorative composite board.

The old residential areas in the city did not carry out the external wall insulation material work when they were built, and now they are gradually carrying out the insulation and energy-saving transformation of the external wall. In addition, when building houses in rural areas now, the external wall insulation construction projects will also be added to achieve a better housing experience.

The horizontal construction should comply with the first positive angle and then the negative angle. First ensure the symmetry and uniformity of special structures (such as doors and windows), and then carry out large-scale construction. Determine the adjustment treatment method based on the measurement results. If the deviation is large, the design size needs to be adjusted, and the design unit will implement it after confirmation with the owner. When loading or construction work, it should be handled with care to prevent the edges, corners and surfaces of the insulation decoration board from being damaged, and at the same time, the board should be prevented from being damaged due to excessive bending. If two workers are transferring together, their arms should be spread out as much as possible on the long side of the board, and horizontal transfer at both ends is prohibited.

When the integrated board of external wall insulation material is in a high temperature and high humidity environment for a long time, its own strength will be significantly reduced, especially the slag wool. When the external insulation system is built on the external wall containing construction moisture, the moisture content will increase during the wall drying stage, affecting the durability of the insulation material. The quality of other alkali-resistant mesh cloths and plastic expansion nails affects the life of the external bonded polystyrene board. In addition, when bonding the polystyrene board, water must be poured on the dry external wall to moisten the wall surface. If the operator is not responsible enough, there may be a phenomenon of water leakage, which affects the bonding effect.
