The reason why the exterior wall insulation material causes cracking is that the building is not fully insulated, which includes components such as awnings. Therefore, when the construction of the building is stopped, the building and other components should be fully insulated. Organize the construction of the technical quality and safety of the exterior wall insulation construction of the homogeneous modified fireproof insulation board system, reasonably plan the period specified by the project contract, and ensure that all the goals determined by this project are achieved.

In order to avoid deformation cracks caused by long-term large deadweight loads on the outside, it is very important to install brackets to reduce the load. In order to save energy and reduce the load of the insulation pipe support and hanger structure in the project, insulation materials with small bulk density should be used as much as possible. The bulk density of general soft and semi-hard materials and the bulk density of hard materials shall not be greater than the maximum use temperature. The manufacturers of exterior wall insulation integrated panels are mainly used for building wall and roof insulation, composite panel insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving, etc. The manufacturers of exterior wall insulation and decoration integrated panels talk about the flame retardant properties of EPS foam plastics.

The use of thermal insulation materials for the exterior walls of houses as insulation layers can not only make the house warm in winter and cool in summer, but also greatly reduce energy consumption during winter heating. However, I believe that many residents will find that after years of use, the insulation layer of the exterior walls will have cracks on a large scale.

The thermal conductivity of the exterior wall insulation materials is greater than that of organic materials. As exterior wall insulation, the thermal engineer calculates that the insulation thickness is about 8-10 cm (in the cold northwest region). The wall safety is worth considering. The biggest disadvantage of organic materials for exterior wall insulation is that the fire rating of the materials themselves cannot reach Class A. The specifications, varieties and performance of various materials meet the design specifications and relevant regulations. After the materials are brought into the site, they must be sampled and re-inspected according to the construction specifications. It is absolutely strictly prohibited to use materials that do not meet the regulations in the project.
