Building insulation materials and systems involve many issues such as resources, energy consumption, environmental protection, safety, health, efficiency, efficiency, cost, and comprehensive utilization. There are many types of thermal insulation materials, such as organic, inorganic, botanical, animal, mineral, etc., all have the function of heat preservation and temperature regulation, but the effects and needs are different. All materials have advantages and disadvantages. When we select and use these materials, we must weigh them from local resources, environmental protection, climate characteristics, safety, health, efficiency, and efficiency.

1, EPS, XPS, XPU materials and systems

In recent years, EPS, XPS and XPU have been widely used in exterior insulation projects of buildings. These materials have low thermal conductivity and are very good lightweight insulation materials. If used in refrigerators and cold storages, it is a good choice. If it is used on the wall of a building, it is a great waste of resources. Its safety and stability will be very poor, it will fall off easily and cause fire. The wall will easily form condensation and mold, once it falls off or the building ends. These materials are difficult to recycle and cause great pollution to air, water and natural habitats. The poisonous substances in these materials will directly harm people's health and even life safety. Many heavy fires in the country cause a large number of casualties and property losses, so that the high-level pains are determined to limit the fire prevention of insulation materials. problem.

Due to safety, fire and environmental protection issues, EPS, XPS, and XPU insulation materials are restricted or prohibited in the country. Therefore, these insulation materials will not have a promising future in construction.

2. Rock wool and other mineral wool

Rockwool insulation materials and their products have good fire resistance and good heat preservation properties. They are suitable for thermal insulation of sandwich color steel plates. Fibrous rock wool, light weight, fragile, cleaned at the production site, construction site or end of life. The broken ends, such as entering the respiratory tract and lungs, will cause lung infection, even fatal lung disease, and skin. Contact, it is easy to enter the skin like acupuncture, making people uncomfortable. Mineral wool insulation material is used for building insulation. After the end of its life, it is very difficult to recycle, process and reuse. If you want to solve these problems, it will be big. Amplitude increases costs and is technically more difficult.

Mineral wool insulation material is different from thermal insulation mortar. The latter is wrapped with cement glue. It does not cause any big problems after water absorption. The rock wool block has strong water absorption. Once the rock wool fiber absorbs water, it will immediately expand or shrink. Will directly affect the stability of the insulation system.

Factors such as resources, energy consumption, economic costs, construction costs, environmental protection and health impacts of rock wool fiber and mineral wool manufacturing processes will affect their market demand and will be more difficult to promote.

3 YT inorganic active wall insulation material

YT inorganic active wall insulation material, A1 fire protection. It is made of natural high-quality insulation material and is very environmentally friendly. Moreover, it has water resistance and does not seep water, so it will not affect the heat preservation effect. The construction is also extremely convenient. It can be directly applied to the wall by directly adding water and mixing, saving labor and time, and low comprehensive cost. It is the best choice for current building materials. This product has been greatly promoted in the market.

With the government's vigorous promotion of energy saving, low carbon economy, YT inorganic active wall insulation materials will be more widely used.
