There are many kinds of external wall insulation. Traditional external wall insulation is made of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials. On-site bonding construction. The new type of thermal insulation and decoration integrated board is produced through the assembly line, integrating thermal insulation, waterproofing, and decorative functions. It is the preferred material to meet the current demand for energy-saving housing construction and improve the external wall insulation level of industrial and civil buildings. It is also energy-saving for existing buildings. The preferred material for transformation.
What are the external wall insulation materials?
External wall thermal insulation materials are divided into inorganic and organic according to their composition properties. Generally speaking, organic thermal insulation materials have very good thermal insulation effects, but have low fire resistance. Inorganic thermal insulation materials have good fire resistance, but they have very poor thermal insulation effects. What are the wall insulation materials?
1. Benzene board, benzene board is now used more, but its thermal insulation effect is not ideal, it will absorb water, so if benzene board is used, some waterproof measures will generally be taken.
2. Extruded board, which is much better than benzene board, has lower thermal conductivity than benzene board, and the price is slightly higher.
3. Polyurethane is a relatively high-end thermal insulation material and the best performance. Generally speaking, it is used in some places with extremely strict requirements in this respect, and because of its high price, there are fewer residential buildings.
Four, glass wool and rock wool, glass wool and rock wool have many similarities in performance, and many people are easy to confuse them, but because glass wool has a better hand feel than rock wool, its price is generally higher than rock wool.
