With the continuous development of building energy saving, the heat preservation and heat insulation of building structure, as an important part of building energy saving, has become a new field of energy-saving building technology research and application in our country.

Mineral wool mainly refers to rock wool, mineral wool, glass wool, aluminum silicate wool and their products. It has small bulk density, low thermal conductivity, good chemical stability and it is also non-combustibility, heat resistance, frost resistance, corrosion resistance, resistance to insects. Since the 1950s, mineral wool has been mainly used for industrial insulation. Now it is widely used in various types of buildings, and a relatively complete product system has been formed. The product categories include felt, board, tube shell, block, mat, rope, board and so on. Mineral wool is the main heat-insulating and sound-insulating material in our country’s industry and construction. 

Extruded polystyrene (XPS) is a new type of thermal insulation material developed abroad in the 1950s and 1960s. It has the characteristics of low thermal conductivity, low water absorption and high compressive strength. Its thermal insulation function, unique resistance to vapor permeability, extremely high compressive strength, and easy processing and installation. The production process of XPS is to heat and extrude the melted polystyrene resin or its copolymer and a small amount of additives and foaming agent in a specific extruder, stretch it by a pressure roller and in the vacuum forming zone (some processes do not require (Vacuum forming) cooling. The application of XPS in the construction field mainly includes (1) thermal insulation materials in composite walls; (2) building underground wall foundation; (3) roof internal and external thermal insulation; (4) roof thermal insulation; (5) ) Highways, airport runways, parking lots and other places that need to prevent pavement re-slurry and must resist pressure; (6) Cold storage and other low-temperature storage equipment.
