Glass wool is inorganic fiber thermal insulation material, thermal insulation effect is one of the important indicators to measure the quality of glass wool, and thermal conductivity determines the thermal insulation effect of glass wool.  That glass wool insulation effect exactly how?  This question is actually asking how much is the thermal conductivity of glass wool, its thermal conductivity can do the minimum, which depends on the quality of glass wool and glass wool fiber diameter and its bulk density, need to be measured in many ways, is not a single consideration standard.  


Thermal insulation material is the guide thermal coefficient is less than or equal to 0.12 material, there are a lot of thermal insulation materials can do thermal conductivity is less than or equal to 0.12, but now with the increasingly high requirements for energy saving thermal insulation, the thermal conductivity of thermal insulation materials is also more stringent, there is a good thermal insulation effect of thermal insulation materials on the market.  Glass wool is one of the high-quality thermal insulation materials, and is an inorganic fiber thermal insulation material, with certain fire performance, it is understood that the thermal conductivity of glass wool can do 0.034, formaldehyde-free glass wool can do lower thermal conductivity.  


Compared with other thermal insulation materials, glass wool has certain advantages in thermal insulation effect.  Glass wool fiber diameter is thin, distribution more uniform, the coefficient of thermal conductivity is lower, so the glass wool fiber diameter size determines the coefficient of thermal conductivity, also can ensure that glass cotton good heat preservation performance and other indicators, can guarantee the product the durability of the heat preservation effect, usually have related certificates of test report to prove.  As a thermal insulation material, glass wool has low thermal conductivity and other performance advantages. In general, the thermal insulation effect of glass wool is obvious to all, and has been certified and practiced by the thermal insulation industry.
