在建筑的围护结构中,门窗被称为了建筑的“眼睛”。但是,它却是保温的薄弱环节,门窗作为热交换和热传导最活跃、最敏感的部位,传热和失热的损失是墙体的5-6倍,门窗和玻璃的节能效果,占据着建筑节能的40％左右。因此,如何让建筑的“眼睛”保温,便成为了人们非常关注的问题。前景广阔的节能门窗 In the building envelope, the doors and windows are called the “eyes” of the building. However, it is the weakest link in thermal insulation. Doors and windows are the most active and sensitive part of heat exchange and heat conduction. The loss of heat and heat loss is 5-6 times that of the wall. The energy saving effect of doors, windows and glass occupy the building About 40% energy saving Therefore, how to make the building's “eyes” insulation, it has become a matter of great concern to people. Prospects of energy-saving windows and doors
