  • The Function of Window Sound-insulation Seal

    The window is the most demanding decorative place in the home, so do you know about this window soundproof seal?Thus,we want to introduce the functions of the window sound-insulation seal,and the using methods of it.

    1. The functions of window soundproof seal

    (1).Sealing strips play an important role in waterproofing, sealing and energy UPVC doors and windows and broken aluminum doors and windows, and wooden doors and windows,also play the role of sound-insulation, dust-insulation, anti-freeze and keep warm. It must have strong tensile strength, good elasticity, and better temperature resistance and aging resistance. In order to ensure the fastening of the strip and the profile, the cross-sectional structure of the strip must match the profile of the  door and window. Sealing strips are generally used to casement doors and windows,top hung windows, and folding doors and windows. The main functions are dust-proof, insect-proof, waterproof, soundproof, sealing and so on.

    (2).The installation position of the mohair weather strip is generally on the sliding window (door) sash, around the frame sash or on the sealing bridge (wind block), and the sealing between the frame and the sash is enhanced. The mohair weather strip specification is an important factor to affect the smoothness and watertight performance of sliding door and window, and also an important factor to affect switching force of door and window . If the mohair weather strip size is too large or the vertical hair is too high, not only the assembly is difficult, but also the sliding force of the door and window is increased, especially the initial force at the time of opening and the final seating resistance at the time of closing. If the specification is too small, or the height of the vertical top wool weather sealing strip is not enough, it is easy to get out of the slot, so that the sealing performance of the door and window is greatly reduced.


    2. The using method of sound-insulation weather strip

    (1) .There are many types of sealing strips, and the applicable range of different seals is different. Therefore, when selecting the type of door and window mohair weather seals, it must correspond to your own doors and windows, so that the doors and windows can be more tight. Pay attention when purchasing seals, should choose non-toxic and tasteless environmental seals.

    (2) .The top wool weather strip are generally installed around the door and window sashes and the frame sashes. The surface of the good quality top wool weather strip is straight and not curved, and the vertical hairs are smooth and uniform without lint. The specifications of the sealing strip should be matched. If it is too small, the sealing strip will fall off, which will affect the tightness of the glass and the sash. Excessive assembly is difficult, and the force to movement of doors and windows becomes large, which is causing inconvenience.

    (3) .There are special slot grooves on the doors and windows and the beading to install the mohair weather strip. When installing the sealing strip, the notch debris should be carefully removed to ensure uniform gap on both sides. The mounting part must be flat, not stretched, not curled, and the joint should be less than 1MM. .
