Sealing strip configuration of aluminum-clad wooden doors and windows

Aluminum-clad wooden doors and windows are called "N95" in doors and windows by industry insiders. Because of their outstanding thermal insulation and sound insulation, they can isolate external noise pollution more effectively than broken bridge aluminum windows.

And its better sound insulation and heat preservation, partly depends on its main material is solid wood, the conductivity of wood is lower than aluminum, so the heat insulation is better; another part depends on the configuration of the sealing strip.

The use of door and window sealing strips can be divided into three categories: glass sealing strips, door leaf and door cover sealing strips and wool strips. Among them, the glass sealing strip is used to seal the gap between the glass leaf and the frame. The door leaf sealing strip is used to seal the gap between the door panel and the door frame, and the sealing tape is mainly used to seal the gap between the frame and the door. Therefore, in the installation process of various doors and windows, the sealing strip is indispensable.

Sealing strips have very high requirements for materials. First, they must have strong stretchability and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure close contact between the sealing strip and the profile, the cross-sectional structure of the sealing strip should match the profile of the door and window.

It is known that the sealing strips of doors and windows are mostly made of EPDM material, and the better is automobile-grade composite sealing strips, and the sealing strips of aluminum-clad wooden doors and windows can also be covered sponge sealing strips. The elasticity and toughness of the window are very good. It can effectively improve the sealing performance of the aluminum-clad wooden window between the opening and closing of the window, and the aging resistance is the leader of the current materials.
