2018-06-20 09:16:27

Installation and use of building doors and windows require sealing strips to achieve a closed seal between the profile and the glass and between the fan and the frame. The sealing strip plays a role of fixing glass in the use of doors and windows, buffering vibration and blocking water and airflow. The insulation performance and airtight performance of doors and windows have a significant impact on energy saving and consumption reduction of buildings. Poorly sealed doors and windows suffer from heat loss, which is 5-6 times the heat loss of the wall. The energy efficiency of doors and windows and curtain walls accounts for about 37-40% of building energy efficiency. Therefore, the rubber strip is a functional accessory that can not be ignored in the energy-saving standards of doors and windows, and its performance and service life should arouse our attention.
