Sealing strips play a role in fixing glass, buffering oscillations, and blocking water and air flow in the application of doors and windows.

  The insulation and airtightness functions of doors and windows have a serious impact on energy conservation and consumption reduction of buildings. The heat loss of poorly sealed doors and windows is 5-6 times that of walls. The energy-saving power of doors, windows, and curtain walls accounts for about 37-40% of the construction energy-saving. So the rubber strip is a functional accessory that cannot be ignored in the energy-saving qualification of doors and windows, and its function and service life should be of concern to us.  

  At that time, due to various reasons, the quality of the rubber strips varied. Many developers and door and window companies are using sealing strips that do not comply with the specifications of "Building Sealing Strips for Doors and Windows" due to low prices. It is necessary for rubber strip manufacturers to further increase their attention to the energy-saving door and window industry.

  It is also necessary to improve the identification technology of sealing strips in various aspects such as development, supervision, and door and window manufacturing. When selecting sealing strips, attention should be paid to the following aspects to promote the general improvement of door and window sealing quality.
