Characteristics of external wall insulation board What kinds of external wall insulation boards are there?

With the development of society, the progress of science and technology and the improvement of people's living standards, people's pursuit of quality of life is getting higher and higher. It's cold in winter in the north, so when building a building, the external wall will also use thermal insulation boards, which will not only make the home warmer, but also be green and convenient to construct. Seeing this, you must want to know more about the external wall insulation board. Below, Bian Xiao will give you a detailed introduction.

First, the characteristics of external wall insulation board

1, environmental protection, 100% of the base material does not contain asbestos components and radioactive elements;

2, heat preservation, energy saving, waterproof, decoration in one.

3. Melting resistance and chemical corrosion resistance;

4. Factory production, stable product quality.

5. Simple construction, one-time operation, short cycle, high efficiency and reduced wet operation.

6. The surface layer can be made into various colors and patterns according to the design requirements, which is beautiful and neat.

7. Wide application range and low comprehensive cost.

8. The construction is simple, and the plate is easy to be sawed, drilled, directly pasted or installed.

9, good viscosity, solid and reliable.

Second, the types, advantages and disadvantages of external wall insulation board

At present, there are many kinds of external wall insulation materials on the market, which can be divided into organic insulation materials and inorganic insulation materials. Materials include inorganic active thermal insulation materials, foamed plastics, mineral wool products, foamed glass, expanded perlite thermal insulation products, rubber powder EPS particle thermal insulation slurry, mineral cotton spraying, foamed cement thermal insulation products, vacuum thermal insulation board, etc.

1, the inorganic fire resistance of rock wool board is Grade A, and the thermal conductivity is 0.04 1-0.045? Fire prevention, flame retardant, moisture absorption, poor heat preservation effect;

2. The inorganic active thermal insulation material is Class A fire-resistant, with thermal conductivity of 0.050-0.055, good fire-proof and thermal insulation effect, and simple construction (no need for grid cloth, anti-crack mortar, etc.). ), and the same life as the building, waterproof, anti-cracking, anti-hollowing;

3. The inorganic fire resistance of ceramic insulation board is Grade A, and the thermal conductivity is 0.08-0. 10? Fireproof, non-combustible, non-absorbent, convenient construction and durable;

4. The inorganic fire resistance grade of slurry such as vitrified beads and perlite is Grade A, and the thermal conductivity is 0.07-0.09? Good fire resistance, poor high temperature resistance and heat preservation effect, high water absorption;

5. Expanded polystyrene board (EPS board)? Organic refractory B2, thermal conductivity 0.037-0.045438+0? Good heat preservation effect, low price and slightly poor strength;

6. Extruded polystyrene board (XPS board)? Organic refractory B2, thermal conductivity 0.028-0.03? Good thermal insulation effect, high strength, high moisture resistance, and the surface needs to be treated during construction;

7, rubber powder polystyrene particle thermal insulation slurry organic refractory B 1 grade, thermal conductivity of 0.057-0.06? Good flame retardancy, unsatisfactory heat preservation effect of waste recycling and high construction requirements;

8. The organic fire resistance rating of polyurethane foam is B 1 grade, and the thermal conductivity is 0.025-0.028? Good waterproof, good thermal insulation effect, high strength and expensive price;

9. Phenolic resin composite board organic refractory material B 1 grade, with thermal conductivity of 0.029-0.03? Good thermal insulation effect, high strength, high moisture resistance, and the surface needs to be treated during construction;

10, HD-STP ultra-thin vacuum insulation board, inorganic fire resistance grade A, super thermal insulation performance, thermal conductivity below 0.008, outstanding energy-saving effect, insulation effect is 3-8 times that of other traditional insulation, and the required insulation thickness is 1/3 to 1/8. It adopts inorganic, non-toxic core material, low energy consumption and zero emission processing technology, does not produce waste gas and wastewater, and belongs to environmental protection and low carbon thermal insulation materials. Light weight, convenient transportation and handling, simple construction technology and high pasting efficiency. The price is higher, because it is made of vacuum material, it can't be cut and bent on site, and it is strictly forbidden to hit heavy objects and pierce with sharp instruments.

The introduction of external wall insulation board has come to an end. The above is the external wall insulation board introduced by Bian Xiao. I believe that after reading Bian Xiao's introduction, you have a certain understanding of the external wall insulation board and a certain idea of what kind of external wall insulation board to buy in the future. Everyone must buy according to their actual situation when buying. I hope Bian Xiao's introduction can help everyone and make everyone's life better.
