As the attic is located on the top floor, the thermal insulation effect is poor. It is hot and humid in summer and dry and cold in winter. It is difficult to control the temperature of the narrow attic. The solution is to solve the temperature problem, indoor and outdoor needs to be transformed at the same time. Outdoor insulation layer can be paved on the top surface; Wood keel+thick insulation board+gypsum board can be used to build thermal insulation layer indoors to prevent the attic from becoming a “steamer” in summer. The insulation board shall be made of materials that are healthy, environment-friendly, fire safe and have good thermal insulation effect.
Phenolic composite thermal insulation gypsum board (also known as gypsum board faced phenolic foam thermal insulation board) is composed of paper faced gypsum board and phenolic foam thermal insulation board.
Phenolic compound thermal insulation gypsum board is mainly used for internal thermal insulation of building exterior wall (internal thermal insulation inside the building exterior wall). This method can achieve the effect of energy saving and plastering decoration of gypsum board inside the exterior wall at one time. It is a safe, reliable and cost-effective solution for building energy conservation.
In China, since the vast majority of external walls are single layer masonry or reinforced concrete structures, the use of external wall internal insulation has the following four special advantages:
–External wall internal insulation is a convenient and economical solution, which will not affect the existing facade
–Exterior wall internal thermal insulation veneer system is a very safe choice for high-rise buildings
–Most of China’s regions with rapid economic development are located in relatively mild areas. The external wall and internal insulation can easily meet the energy saving requirements of these regions, and do not occupy too much internal space
–For commercial buildings that are not often used or residential buildings that use independent heating/cooling, internal insulation is more suitable, because it can reduce the energy consumption of heating/cooling through the wall and quickly adjust the indoor temperature
At present, according to the application of the thermal insulation system in China, the building thermal insulation system is still an external thermal insulation system, and the market share of the internal thermal insulation system is small. In France, Britain, Japan, etc., the thermal insulation system inside the building thermal insulation system is mainly used, while in Germany and the United States, the thermal insulation system outside the building thermal insulation system is mainly used. Both internal insulation and external insulation have their own advantages, disadvantages and scope of application. At the same time, they are restricted by climate regions and building types. There is no absolute difference between good and bad systems. According to the different characteristics of each building, climate distribution regions and local actual conditions, the key to energy conservation is to select the most suitable insulation system.
In fact, the internal thermal insulation system of composite thermal insulation gypsum board has been used abroad for more than 40 years. It has been proved by practice that the technology is mature and the performance is safe and reliable.
