Background

Cold bridging: also called thermal bridge, this is a different name for the same phenomenon in north and south. North is called cold bridge and south is generally called hot bridge: when the building outer enclosing structure conducts heat with the outside, the heat transfer coefficient of some parts in the enclosing structure is obviously larger than that of other parts, so that the heat is intensively and quickly transferred from the parts, the air conditioner, the heating load and the energy consumption of the building are increased, a cold bridge has a destructive effect on the building, the cold consumption of a room is increased, and the energy for cooling is wasted; condensed water exists on the high-temperature side, so that the heat insulation performance of the heat insulation material is influenced; it also affects the use of the high temperature side room. To avoid these situations, the number and area of cold bridges are reduced as much as possible, and the inevitable cold bridges are wrapped with heat-insulating materials.

In general, various heat-insulating cotton is adopted for cold bridge prevention, but in the actual operation process, heat loss can be caused by compression of the heat-insulating cotton, and the cold bridge prevention performance of the heat-insulating cotton needs to be improved.
