Construction method of centrifugal glass wool board for external insulation of external wall in construction engineering
Centrifugal glass wool is an inorganic incombustible material with light weight, low thermal conductivity, excellent heat insulation, sound absorption and noise reduction performance. Glass wool has high tensile strength, strong seismic performance of the structure, and is not easy to sag, fall and collapse during construction, installation and use. High fireproof performance: centrifugal glass wool is a non combustible A-grade fireproof material, which is a good choice for thermal insulation, fire prevention and fire partition. Strong hydrophobicity: centrifugal glass wool does not absorb water itself, it is easy to dry after being soaked in water, with good resilience and stable thermal insulation performance. Stable chemical performance: centrifugal glass wool does not rot, mildew, nor cause corrosion of metal materials. Its mold resistance, corrosion resistance, and durability are higher than rock wool. The construction and installation are convenient and fast: because the centrifugal glass wool does not contain slag balls, it has a good hand feel, and can also improve the working conditions of workers, avoiding the itching stimulation caused by the scratch of the construction operator (rock wool is easy to cause the itching injury of the operating skin); At the same time, the material is soft and easy to transport, cut and cut. High cost performance and wide application range: centrifugal glass wool has a low price, which can not only effectively improve the construction efficiency, but also save labor and material costs and shorten the construction period. The construction cost is significantly lower than that of wet insulation materials.
