Under the general trend of energy conservation and environmental protection, insulation board, as an important building energy-saving material, has been widely used in various building walls, roofs and ground insulation projects. So, how long does the insulation board last? There are many factors involved in this, which we'll dive into below.
As an important material for energy conservation in modern buildings, the service life of insulation board is closely related to a variety of factors, including raw material quality, production process, installation method, use environment and maintenance.
1.Material: Different insulation board materials, their durability varies greatly. For example, plastic insulation materials such as polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU) generally have a service life of about 20-30 years; Inorganic fiber insulation materials such as rock wool and glass wool can have a service life of more than 50 years because of their good chemical stability and strong weather resistance; New insulation materials such as graphite polystyrene board and phenolic resin board can improve performance through modification technology and have a longer service life.
2.Production process: high-quality insulation board should have good structural stability, which is closely related to the foaming process, adhesive quality, surface protection treatment and other links in the production process. Excellent production technology can effectively prevent the degradation of thermal insulation performance and physical structure damage caused by thermal expansion and contraction, moisture erosion and other factors, so as to prolong the service life of the insulation board.
3.Use environment: In the actual use of the insulation board, it will be affected by natural conditions such as temperature changes, humidity, ultraviolet radiation, wind, frost, rain and snow. Harsh environments, such as high temperature, high humidity or long-term exposure to the sun, may accelerate the aging rate of the insulation board and shorten its service life.
4.Maintenance: Proper installation and regular maintenance can also significantly affect the service life of the insulation board. For example, do a good job of waterproof and moisture-proof measures, avoid external impact, regularly inspect and repair damaged parts in time, etc.
It can be seen that there is no fixed value for the service life of the insulation board, which depends on the quality of the material itself, the correct construction technology, the suitable use environment and good post-maintenance. If one of the traditional external insulation boards is not strictly met, it may lead to faster aging, thereby shortening the service life.
In order to effectively improve the service life of insulation materials, and improve the energy-saving effect and overall safety of buildings, in recent years, the state has begun to vigorously promote the integration technology of building insulation and structure. This technology closely combines the integrated insulation material with the main structure of the building to form a whole, which not only avoids the problems of easy falling off and poor durability caused by the construction quality and external environmental factors of the traditional external insulation layer, but also can significantly improve the energy utilization efficiency of the building and reduce the energy consumption of the building. WJ reinforced connection composite insulation board is an insulation material designed and manufactured with this concept. It has excellent mechanical properties and thermal insulation properties, can withstand various stresses that may be encountered in the process of use, ensures the same life of the insulation layer and the wall, and greatly improves the stability and safety of the insulation system. At the same time, because the insulation material and the building structure achieve a seamless and no thermal bridge, the heat loss is effectively reduced, and the energy-saving effect of the building is further improved.
Therefore, in order to improve the service life of building insulation layer, it is an effective strategy to realize the integration of building insulation and structure. The integrated technology can not only greatly extend the service life of the insulation layer and improve the energy efficiency, but also an important starting point in line with the current concept of green building and sustainable development, and has important practical significance and strategic value for the long-term development of China's construction industry.
