The type of insulation material is a factor that affects the insulation effect of the exterior wall. The so-called insulation material here refers to whether our insulation is reinforced concrete or ordinary bricks and stones. Additionally, if it is masonry, which type of masonry should be used. The difference is significant. I believe that the thermal insulation performance of aerated bricks is higher than that of ordinary bricks, and the thermal insulation performance of ordinary bricks is higher than that of reinforced concrete.

The function of the protective layer is to prevent the insulation material from being damaged by mechanical impact or other stress, prevent moisture from entering the insulation material to reduce its performance, and beautify the insulation components. The protective layer is made of metal or felt material, and the metal protective layer can be made of galvanized steel plate, ordinary steel plate, stainless steel plate, aluminum alloy plate and other materials. Before installing external wall insulation materials, please carefully inspect each fixed length board for any quality issues. You must pick out the defective fixed length board (if there are bubbles, board corner deformation, etc.) and severely scratch it; Serious color difference; The thickness of the backboard does not meet the design requirements, etc

External wall insulation materials have the same lifespan as the main building, are safe, reliable, easy to construct, and shorten the construction period. This is a significant change in traditional building insulation design and construction methods. The technology of wall insulation materials, as an important measure for building energy conservation, has made a qualitative leap after implementing energy-saving design standards in various regions. Among them, technologies represented by exterior wall insulation have developed rapidly and are favored by many real estate developers in the market. Detailed analysis of the reasons for adopting external wall insulation technology, and improvement of external wall insulation materials from the customer's perspective.

Material selection: Perlite or polystyrene particles are commonly used for exterior wall insulation, mixed with cement mortar and rubber powder to form insulation particles. In the field of wall insulation material technology engineering, inorganic polymer boards are surrounded by a hard calcium carbonate film wrapped in PVC resin, which is an aggregate that combines excellent insulation performance and enclosed space. It is an inorganic foam material that does not burn or melt under flames. Under prolonged combustion, certain areas will undergo carbonization and maintain their original shape.

This material is a high-end material that makes up for the shortcomings of existing organic materials. Due to immature production equipment and processes, wall insulation material technology materials cannot be produced well or in large quantities.
