When constructing exterior wall insulation materials, all personnel have corresponding tasks. Everyone must have a very clear understanding of the relevant standards for work within their scope of responsibility, and some technical tasks must be understood very clearly. There will be no problems with hollowing or falling off. The bonding of exterior wall thermal insulation and decorative integrated panels is the main one, with anchoring as an auxiliary construction technology. It will also be affected by environmental factors and construction factors. When choosing an exterior wall thermal insulation and decorative integrated panel, multiple inspections and comparisons are required.

Corresponding work during construction of exterior wall insulation materials

Glass wool and urea-formaldehyde on-site casting materials can be used. The requirements for construction season and construction conditions are not very high and will not affect winter construction. It has been used to some extent in severe cold areas such as Heilongjiang, Inner Mongolia, and northern Gansu. The control system design of the entire system has been carried out and the application of key technologies such as cavity technology, air intake technology, and moisture-proof technology has been carried out, so that the entire system can be adjusted through the scientifically studied system internals and interact with the external economy of the construction entity.

When exterior wall insulation materials are used as panels, they have poor fire safety properties and low strength and low load-bearing capacity. Especially when used as exterior tiles, they should be upgraded. In addition, the board needs to go through a period of maturation before it comes from the factory and needs to be left for a period of time before it can be used. For buildings with a height less than 24m, when using thermal insulation materials, horizontal fire isolation belts should be installed on each floor.

There are many manufacturers of exterior wall insulation materials, and the quality of their products varies. How to choose a good thermal insulation material has become a concern for many people. The insulation performance index of insulation materials is determined by the thermal conductivity of the material. The smaller the thermal conductivity, the better the thermal insulation performance. At room temperature, the thermal conductivity of loose materials decreases as the particle size of the material decreases. When the particle size is large, the size of the gaps between the particles increases, and the thermal conductivity of the air in between will inevitably increase. The smaller the particle size, the smaller the temperature coefficient of thermal conductivity.
