The external wall insulation material is directly used to establish the insulation system. The establishment of the insulation system requires the preparation of materials such as paint and boards, as well as complete tools, in order to carry out construction according to certain specifications. Firstly, you need to prepare some building materials such as polymer mortar, polystyrene board, fixing devices, standard alkali resistant fiberglass mesh, expansion joint plastic strips, etc. Secondly, you need to use tools such as plastic mixing buckets, paper separators, ink cartridges, screwdrivers, electric mixers, scissors, steel saw blades, coarse sandpaper, and brown brushes. You can rely on some commonly used engineering tools to obtain the necessary tools for the project.

Before construction, the wall surface should be simply treated, cleaned, and then set elastic lines to ensure the overall thickness, and then adjust the polymer mortar, adjust the wall surface, set nets on the wall surface, and lay some insulating materials such as insulating materials. Board of directors, and then fix its success. Adjust the surface of the coated polymer mortar to a good level, and then lay a layered mesh. Afterwards, even if the polymer mortar is completed, it still needs to be recoated. As long as it is accepted without any problems, it can be said that it has been completed.

External wall insulation material refers to the engineering practice of combining materials with good insulation effect with building walls using certain fixing methods (bonding, mechanical anchoring, spraying, pouring, etc.) to form a whole, thereby increasing the insulation strength of the wall. The resistance and thermal capacity of walls achieve insulation or thermal insulation. The system also includes waterproofing and fire protection engineering.

Building fires are caused by people who do not want to see them, so choosing non combustible materials as insulation materials is the main means to solve building fires. Rockwool is a harmless material, non flammable, and an A-grade fire-resistant insulation material that can withstand temperatures above 1450 degrees Celsius. After multiple tests, the fire department has determined that rock wool cannot be ignited. You can rest assured that using rock wool insulation system can fully meet the insulation effect and ensure that the fire resistance meets the fire standards.

The high-quality rock wool produced in China is Class A non combustible material. Fire resistance is its own characteristic and does not require changing other properties of rock wool. In addition, the tensile strength, water absorption, durability, and insulation performance of rock wool can fully meet all the requirements of the external insulation system. Of course, rock wool is non-toxic and does not cause cancer. All friends who have said this sentence have been misled by asbestos. They believe that rock asbestos and asbestos are one type. Actually, the two are different.

All or most of the production waste from modern factories can be recycled and reused. After treatment, the pollution caused by the discharge of waste will be reduced to the lowest level, fully meeting the requirements of China's environmental protection. The production of 1 kilogram of rock wool consumes about 20 megajoules of energy, while the production of 1 kilogram of polystyrene insulation board consumes at least 85 megajoules of energy. The main raw materials for producing rock wool are very ordinary basalt and other stones, with almost no reserves. Producing one unit of rock wool can save 100 times the energy consumption. Therefore, the production and use of rock wool products is a low-carbon behavior that is conducive to environmental protection.
