The reason of fire in external wall insulation materials

- Jun 08, 2019-

First, the analysis of the cause of fire on the external wall insulation materials First, the industry standards are not perfect, the product quality is uneven. At present, the production and use of external thermal insulation materials are disorderly. The organic thermal insulation materials currently used in the construction field mainly include polystyrene board (EPS), extruded board (XPS) and polyurethane (PU). The biggest advantage is that Light weight, heat preservation and good heat insulation. The biggest drawback is poor fire safety, aging and easy burning.

Second, the construction period is long, and the hidden dangers on the job site are clustered. For the construction industry, wall insulation is an important means to achieve building energy efficiency, so the application of building insulation materials is very extensive. In reality, the construction period of high-rise buildings, large stadiums and other buildings is generally two to three years, and various construction processes cross each other and management is inconvenient. Individual management personnel neglected the investigation and remediation of fire hazards on the spot and the temporary water use of firefighting, and put all their energy into catching up the construction period and compressing the cost.
