As a new type of thermal insulation material - vacuum insulation panel is undoubtedly a dazzling new star in the field of thermal insulation, it has some advantages over similar thermal insulation materials, but also some obvious shortcomings. Vacuum insulation panels have extremely low thermal conductivity, and the thermal conductivity of vacuum insulation panels is generally around 0.005W/m.k. The production process and the selection of raw materials are well controlled, and the thermal conductivity can reach below 0.004W/m.k, which is more than 5 times that of other thermal insulation materials. As a high-tech product, vacuum insulation panels have unparalleled application advantages, ultra-low thermal conductivity index and excellent fire performance, thermal insulation performance can be disdainful of all other types of thermal insulation materials, combustion performance reaches Class A, low water absorption , has a very good water barrier effect. Due to its extremely low thermal conductivity and the same thermal insulation effect, it can be made very thin. The use of vacuum insulation panels for external wall thermal insulation has high space utilization rate, which can reduce the building volume ratio, increase the actual use area, and prevent the external wall from catching fire. Disasters occur, long service life, light unit weight and other characteristics are far superior to similar products.


Advantages and disadvantages of vacuum insulation panels


In the case of a new type of product and a relatively short period of time, the vacuum insulation panel also has its own obvious shortcomings. At present, the production cost is relatively high, so the price is not very cheap; in addition, the size has been fixed during production. Secondary cutting cannot be performed during the construction process; when used in buildings, the existing construction technology may lead to too many board seams, resulting in too many thermal bridges, which is easy to cause the risk of condensation; the construction flatness is also difficult to control, and thin plastering There is also a greater risk of the system falling off; in the event of a breakage, the insulation properties of the panels will plummet. Any product has its advantages and disadvantages. As a high-quality thermal insulation material, the above-mentioned questions and disadvantages cannot cover up its excellent thermal insulation and fire resistance performance, nor does it affect its vigorous promotion and application, and will be used in future production. , In the process of use, overcome and overcome shortcomings, and use and play better advantages. Vacuum insulation panels have a very wide range of applications and are one of the most promising new materials in the future.
