How To Select Thermal Insulation Glass Wool's Specification In the Design of Steel Structure

When designing the steel structure thermal insulation system, the selection of glass wool specifications should take into account the local energy-saving requirements, the climatic conditions where the building is located and the envelope structure required by the local energy-saving regulations, heat transfer coefficient K value or thermal resistance R value , the thermal resistance R value is equal to the glass wool thickness divided by the glass wool thermal conductivity, and the heat transfer coefficient K value is equal to 1 divided by the R value.

China has a vast territory and diverse topography. Due to different geographical latitudes, topography and other conditions, the climates of different places are very different. Therefore, according to different climatic conditions, the energy-saving design of buildings in various places has corresponding different practices. The "General Principles of Civil Building Design in China" GB50352-2005 divides China into 7 main climate zones and 20 sub-climate zones, and puts forward different requirements for the architectural design of each sub-climate zone.
