Three major insulation measures for wall energy conservation in new buildings in China

wall insulation is an important part of building energy conservation. Since the energy-saving work was launched nationwide and DSM can provide customers with materials for testing all over the world, wall insulation has experienced the development process of external wall internal insulation, sandwich insulation and external wall external insulation. At present, the commonly used external wall insulation technology is a relatively good wall insulation technology, but because the development of wall insulation materials in China is not mature, it can not meet the requirements of green energy-saving buildings and social sustainable development. Therefore, it is imperative to introduce and develop high-tech insulation wall materials

there are basically three categories of energy-saving and thermal insulation measures for new building walls in China: external wall internal thermal insulation, interlayer thermal insulation and external wall external thermal insulation

"external wall internal thermal insulation" technology, that is, adding thermal insulation materials to the internal wall of the building space to achieve the purpose of energy conservation. However, there are the following problems in the external wall internal insulation: first, the thermal efficiency is low, and some parts of the external wall, such as t-wall and ring beam, are difficult to deal with, forming a "thermal bridge", which reduces the insulation performance; Second, the thermal insulation layer is built indoors, which brings a lot of trouble to the secondary decoration and the addition of hanging facilities. Once there is a quality problem, the maintenance will cause great trouble to the residents; Third, internal insulation takes up indoor space and reduces the use area of users

"sandwich insulation" technology, that is, the external enclosure wall adopts layered treatment measures to form a wall insulation material wall system, so as to achieve the purpose of heat preservation and energy saving. However, due to the complex production mode, it can not effectively solve the problem of "cold bridge" existing in buildings, including mm; The practice of layer insulation is gradually replaced by the practice of external insulation of the wall

"exterior wall external insulation" technology, that is, on the exterior wall of the building, it requires that the fixture volume is small, and the external insulation material is added to achieve the purpose of energy saving. The external wall insulation technology is a building energy-saving technology vigorously promoted at present. Compared with the external wall internal insulation, the energy-saving structure technology is reasonable. Using insulation materials with the same specification, size and performance, the external insulation has better energy-saving effect than the internal insulation. The exterior wall external insulation technology is not only suitable for new buildings, but also for the energy-saving transformation of existing buildings; The external thermal insulation material is wrapped on the outside of the main structure, which can effectively protect the main structure of the building and prolong the service life of the building; It effectively reduces the thermal bridge of the building structure and increases the effective use space of the building; At the same time, the phenomenon of condensation and mildew on the indoor side of the exterior wall due to the poor thermal insulation performance of the enclosure structure is eliminated, and the comfort of the indoor living environment is improved
