According to the width of the wall structure design of the partition joint of the external wall insulation material, the line is drawn (10-15mm), and then the line is attached with masking paper, and then the weather-resistant engineering glue for the external wall insulation decoration integrated board of the new material of the security is scraped. The weather-resistant engineering glue should cover the board width by 2-3mm and the glue depth should be 3-5mm.

When the external wall insulation material polystyrene board is constructed in the rainy season, effective rain protection measures must be adopted to prevent rainwater from washing the wall surface that has just been constructed but the bonding mortar or surface mortar has not yet been initially set. It will not soften when the temperature is high, and will not crack when the temperature is low, and it can adapt to the environment well. It is believed that with the widespread use of foam boards in the construction industry, it can also play a greater role in other fields.

External wall insulation materials can protect the main structure of the building and extend the life of the building. Since the external insulation is to place the insulation layer on the outside of the structure, the stress caused by the structural deformation caused by temperature changes is reduced, and the erosion of the structure by ultraviolet rays is reduced. The thermal insulation performance of polystyrene boards and extruded boards of the same thickness is gradually improved. The polystyrene board is 0.041, and the extruded board is 0.030. So when the same insulation effect is achieved, the thickness of the extruded board is thinner than that of the polystyrene board, but the price of the extruded board is more expensive than that of the polystyrene board.

The wall structure thickness of the insulation material should comply with the relevant regulations of the wall design, the bonding between the insulation board and other structural layers should be firm, the bonding strength and connection method should comply with the regulations, and the handover work should be carried out at the same time. The density of the selected insulation board. Because our insulation board needs to be pasted on the exterior wall, if the density of the insulation board is very poor, the firmness of the material will be very low, and the consequence in the later stage is that the insulation board will fall off the wall.
