2. Its thermal insulation effect is better than internal thermal insulation. Because the material of external wall insulation board is attached to the outside of the wall, external insulation can reduce the construction cost, increase the use area of the house and obtain higher economic benefits.
3. The use of external wall insulation board is beneficial to eliminate or weaken the influence of thermal bridge around the junction of internal and external walls, external wall ring beams, constructional columns, frame beams and the junction of top parapet and roof panel.
4. Because of its strong heat storage capacity, the main structure is indoors. It is beneficial to the thermal stability of the room, can prevent large temperature difference at room temperature and improve the humidity of the wall.
5. The temperature data of the external wall insulation board can protect the main structure, because the insulation layer is placed outside the building envelope. The outdoor climate condition causes great temperature change inside the wall, which occurs in the external insulation layer, buffering the stress caused by structural deformation caused by temperature change, preventing great temperature change of the internal main structure, effectively improving the durability of the main structure and prolonging the service life of the building.
What are the materials of fireproof insulation board? 1, YT inorganic active wall insulation material.
This kind of fireproof thermal insulation material adopts the international advanced thermal insulation system, which is a kind of thermal insulation material in the building thermal insulation industry and is convenient and quick to use. When it is used, just add water and stir it, and it can be painted on the external wall of our building. It has the properties of heat preservation, heat insulation, waterproof, crack resistance and fall resistance, and is an environmentally friendly, energy-saving and heat-insulating energy-saving material.
2. Foamed silicate materials.
This material is mainly made of cement, some pulverized coal and other cementing materials. It has good high temperature resistance, aging resistance and flame retardant properties.
3. Autoclaved aerated concrete.
This fireproof and heat-insulating material is made of cement or lime and some sand. Adding aluminum powder, then adding water, stirring, forming, puffing, cutting and curing.
4. Poly lightweight high alumina brick.
This material has high porosity, so it has good heat insulation and high temperature resistance. It is widely used in masonry industry which needs heat preservation or insulation layer, so this material can reduce the weight of kiln, shorten the kiln and keep the furnace temperature uniform.
