The external wall insulation integration should be arranged in horizontal order, the upper and lower layers should be staggered, the corners should be staggered, the boards should be tight, the board seam width should not be greater than 2mm, there is no adhesive, and the insulation board seams should be filled with polyurethane and the surface should be smoothed.

The external insulation and structure have different lifespans, renovation disputes and other issues. The overall process places the YAPU rigid foam polyurethane composite insulation board inside the concrete wall. The insulation layer does not need to be repaired or maintained, and is basically not affected by the external environment, which solves the problem of easy shedding of external wall insulation. The selection of external wall insulation materials is conducive to eliminating or weakening the damage caused by deformation near the junction of the inner wall, wall ring beam, fine stone pump, frame column and high-rise ring beam and the building. Due to its strong heat storage capacity, the main project is on the side of the room.

The integrated decorative energy-saving external wall insulation adopts factory prefabrication production, modular specifications and sizes, and direct wall installation, which is simple, convenient and saves construction time. The combustion performance index of the board is also one of the important factors for selection, which can be selected according to the different requirements of different buildings for combustion levels.

This type of material generally has the dual defects of energy saving and fire prevention. Organic matter has poor heat resistance and is easy to burn. When burning, it releases a lot of heat and produces a lot of toxic smoke, which not only accelerates the spread of fire. Generally speaking, the construction thickness of the insulation material can be completed in one go within 20mm-25mm, the thickness of the insulation material can be completed twice within 30mm-40mm, or composite insulation can be performed in 1 inside and 2 outside.

All processes of integrated exterior wall insulation can be completed on the same day, and the surface can be pasted after 7 days. Temperature has an important influence on polyurethane foaming. Foaming is carried out by heat. If there is no heat, the foaming agent in the system cannot evaporate. Under high temperature conditions, the environment provides heat to the reaction system, which can speed up the reaction and shorten the reaction time.
