External wall insulation is the most scientific and efficient insulation and energy-saving technology, which involves placing insulation materials on the outside of the main enclosure structure. This not only achieves the purpose of thermal insulation, but also protects the main structure of the building and extends its service life. This technology effectively solves the problem of energy loss caused by large indoor and outdoor temperature differences in winter and summer, representing the development direction of energy-saving insulation technology. The external wall insulation system does not generate thermal bridges, therefore it has a good building energy-saving effect.

In winter, when indoor heat attempts to pass through wall insulation materials, it will be effectively blocked, thereby reducing indoor heat consumption; In summer, wall insulation materials can also prevent solar radiation and external heat from entering the interior, thus creating a comfortable environment in buildings that is warm in winter and cool in summer. Commonly used building exterior wall insulation materials, currently widely used in building exterior wall insulation materials, but their insulation effect is not ideal and they will absorb water. Therefore, the use of polystyrene board generally requires some waterproof measures.

In terms of external insulation for building walls, extruded polystyrene board is much better than polystyrene board. Its thermal conductivity is relatively low, and its price is slightly higher than that of polystyrene board. Polyurethane is a relatively insulating material and a good material. Generally speaking, it is used in some demanding places, and due to its high price, there are few houses available. Glass wool and rock wool have many similarities in performance. Many people are easily confused, but because glass wool is better than rock wool, its price is usually higher than rock wool.

XPS extruded polystyrene foam board is a new type of external wall insulation material. Also known as polystyrene extruded polystyrene board (XPS), it has a beautiful closed cell honeycomb structure, with lower density, water absorption, thermal conductivity, and air permeability than other types of insulation materials and insulation mortar. Thermal insulation mortar is a pre mixed dry powder mortar made of various lightweight materials as aggregates, cement as cementitious material, modified agents added, and mixed by enterprises. Mainly used for building exterior wall insulation, convenient construction, and good durability. Phenolic foam Phenolic foam is internationally recognized as a new type of building insulation materials. Because this new material is fundamentally different from ordinary polymer resins, which rely on materials with added flame retardants. It will not burn or melt in fire.

External wall insulation materials have the advantages of light weight, non toxicity, non corrosion, insulation, energy saving, sound insulation, low price, high strength, light weight, good air tightness, corrosion resistance, etc. Anti aging, low cost, widely used for thermal insulation. In the material. In the construction industry, highways, railways, airports, squares, antifreeze insulation, home decoration and other fields.
