Analysis of suitable external wall and roof insulation materials

In building energy-saving technology, energy saving of the external protection structure is an important link. As an important way and means of building energy conservation , external wall insulation has been widely used and popularized in just ten years.

Suitable exterior wall and roof insulation materials should meet the following basic conditions:

First, the material has excellent thermal insulation properties and meets the requirements of national building energy efficiency standards;

Second, the burning performance of the material meets Class A fire protection requirements and meets the building fire safety standards;

Third, the material has good waterproof performance and has non-absorbent or long-term hydrophobic properties;

Fourth, the material properties are stable and not easy to age, to meet the building insulation durability requirements;

Fifth, the construction method of the insulation system is simple and efficient, to adapt to the modernization characteristics of the building;

Sixth, the built insulation system has low maintenance cost and meets the requirements of social development and resource conservation.

There are many new types of inorganic insulation materials available on the market.

STP insulation board is made of inorganic fiber materials such as silicon powder and mineral wool. It uses vacuum insulation to improve the insulation performance of the board. The new insulation board processed and manufactured has ultra-thin and light weight, low thermal conductivity and non-combustible materials. Excellent thermal stability, service life and the same life of the building, including heat preservation, fire prevention and decoration. In particular, the low water absorption rate of the STP insulation board not only solves the problem of water absorption of the insulation material, but also contributes to improving the waterproofing and system safety of the entire building.

The application of inorganic thermal insulation materials is still expanding. Glass wool is also an excellent thermal insulation material. The slender glass fiber separates the air into small air bags and shields them well, effectively preventing heat. And the transmission of sound waves, reducing heat loss and reducing noise. Building dry powder is a new type of energy-saving green material with superior performance. The dry powder mortar with special materials added is outstanding. Such as lightweight block special supporting material series, interface treatment agent series, wall and floor tile adhesive series, wall and floor tile filling series, interior and exterior wall putty series, Ziliuping floor treatment series, cement-based elastic waterproof membrane, external insulation System and premixed dry mortar. At the same time, equipped with special mortar mechanization equipment can make the bagged dry mortar with accurate ratio, high spray density, strong adhesion, uniform distribution, easy leveling, and reduced manual operation. The construction effect is 5 times that of traditional plastering. the above.
