Heat preservation material for curtain wall

Speaking of “wall material”, we may feel strange, in fact, it is like the coat of the building, the curtain wall building plays a role of enclosure and heat insulation. In the heat loss of the whole building, the heat loss of the envelope structure as the insulation of the building wall reaches 70%~80%. Therefore, strengthening the insulation of the envelope structure is an important part of building energy saving.

Wall insulation is the most important part of building energy consumption, and its energy consumption accounts for the largest proportion in the whole building energy consumption. Its thermal insulation performance directly affects the heat loss of the building, the design of heating system and indoor thermal environment. With the development of new building materials industry and the improvement of building energy conservation requirements, wall insulation materials are correspondingly transformed to new materials, making the building system in the energy consumption to a minimum. The traditional thermal insulation technology and process, to a large extent, has been unable to meet the requirements of building energy conservation design in China. With the comprehensive development and deepening of building energy conservation, the integration of building energy conservation has become an important direction of the development of curtain wall system.
Glass wool insulation material is an important variety of wall insulation material. Glass wool with light weight, low thermal conductivity, good heat resistance, aging resistance, easy to bond with other substrates and other excellent performance. In Europe and The United States, it is widely used in building roof, wall insulation, ceiling, floor, doors and windows as a thermal insulation material. At present, about 49% of the building insulation materials for curtain wall structure in Europe and the United States and other developed countries are glass wool insulation materials, and the application proportion of glass wool insulation materials in China is more than 75%. In terms of energy saving, glass wool wall insulation material is the most energy-saving material of all wall insulation materials. From the different thermal insulation heat transfer coefficient of materials, we can distinguish the advantages and disadvantages of material energy-saving thermal insulation. It has the lowest heat transfer coefficient and the best heat preservation and energy saving; From the point of view of environmental protection, glass wool insulation material is low smoke, low toxic new material, which does not pollute the environment, even in the event of fire, but also because of its efficient carbonization layer protection to protect the environment; From the point of view of livable, glass wool wall insulation material has strong adhesion, stability, good material coverage, the curtain wall facade will not fall off, water leakage and other safety problems; it can form intact and dense insulation and sound insulation, vibration absorption and other auxiliary functions and it is the ideal livable green building material.
