Why is Wuxi Tianyuan family on fire?

The cause of the fire has been ascertained by the fire department. During the installation of aluminum plate on the external wall, the construction workers violated the regulations on site operation and management, and threw unlit cigarette butts on the east balcony to ignite the stacked plastic protective film, which directly led to the fire.

Tianyuan Shi Jia's external thermal insulation material is Irvine Corning's first-class fireproof and flame-retardant thermal insulation cotton. Due to the high-quality fire-retardant performance of this material and the incombustibility of the external wall aluminum plate and stone, the fire did not spread indoors and did not affect the main structure.
