Why ultra-low energy Windows and doors are the most important part of building energy saving and carbon reduction?

As the weak link of insulation of building envelope structure, the energy lost through building exterior Windows is very serious, which is the main reason for affecting the building thermal environment and causing excessive energy consumption.

According to relevant data, in China, building energy consumption accounts for 30% of total social energy consumption, and the energy consumption of doors and Windows accounts for 50% of building energy consumption.

Therefore, ultra-low energy Windows and doors play a very key role in the energy saving and carbon reduction of buildings.

Ultra-low energy Windows and doors

Ultra-low energy Windows and doors are not only a simple functional design, but also a systematic project, which needs to be composed of frame material, glass configuration, structural design, process processing, precision and other factors.

By improving the optical properties, thermal properties and tightness of the material, improve the structure of the doors and Windows to achieve the expected effect of ultra-low energy Windows and doors.

The excellent thermal insulation performance of ultra-low energy Windows and doors can greatly reduce the energy consumption of indoor heating and cooling, thus playing a role in energy conservation and emission reduction.

K value - The key to measuring the insulation performance of doors and Windows

The K value, that is, the insulation of doors and Windows, represents the heat transfer coefficient. The higher the K value, the higher the heat transfer coefficient and the more energy lost; The lower the K value, the lower the heat transfer coefficient, the less energy lost, and the better the insulation effect.
