There is still a long way to go to regulate the use of building insulation materials.

Polyurethane, a building insulation material that has been frequently questioned in recent years, has also been mentioned again. Polyurethane is a polymer synthetic material with outstanding performance advantages such as heat preservation, heat insulation and sound insulation. It is widely used in the field of building insulation, but its flame retardancy has serious defects, even if it is added to flame retardant materials, it is flammable. Most of the insulation materials currently used on the market are polyurethanes. The incident at the Capital Airport was related to polyurethane materials.
As far as the current market application is concerned, due to the doubling of the cost and the labor and time, there are very few inorganic temperature materials. In contrast, the B-grade materials mainly composed of polyurethane and benzene board are popular. Document 65 is also considered to be beyond the capabilities of existing resources and technologies, and its operability is poor. After the introduction, the nationwide building insulation project has been stagnant. At present, it is widely expected in the industry that the relevant fire protection standards will reduce the flame retardant grade of insulation materials. It is impossible to use inorganic insulation materials with high fireproof rating, because it meets the requirements of building energy conservation and safety standards. Construction enterprises strengthen management and strict acceptance system.
The standard use of thermal insulation materials is not a day's work, and it is impossible to completely prevent micro-duration by a single paper. But overall, it is extremely urgent to implement the fire prevention standards as soon as possible. The new fire prevention policy is pending, and the construction of exterior wall insulation materials for many real estates is currently in a state of suspension. Not only that, producers of inorganic insulation materials are also looking forward to it.
