Door and window sealing strip is the key to determine the sealing performance of doors and windows, and it is also one of the important indicators to determine the choice of product structure. Today we will talk about the sealing function of the rubber strip and how to choose and buy In the doors and windows, the function of the door and window sealing strip is: when the window is opened by the hardware lock, it provides a "window frame 'pressure' process". In this process, the surrounding rubber strip is deformed due to pressure, and the deformed rubber strip presses the gap between the sash and the window frame, thereby preventing the penetration of wind and rain. Below to understand the role of door and window sealing strip and purchase skills.

The rubber strip improves the sealing performance of doors and windows, and also positively affects the heat preservation and sound insulation of a heat insulation material. The main reason is to cut off the conduction of temperature and sound from the flowing ambient air of the enterprise.

Common positions of door and window sealing strips

More commonly, the tape will appear in four to five locations in the door and window structure:

There are two or three rubber strips on the doors and windows, and sealant on both sides of the glass;

There are two or three rubber strips at the door and window position, but the two sides of the glass are replaced by rubber strips;

Some have only one middle rubber strip and one rubber strip on the inside of the room for structural design through doors and windows, and there is no rubber strip between the outside. Is it better to glue the inside and outside of the glass or to press the rubber strip?

There are two kinds of adhesive strips and glue for the connection position of glass and window flap.

When the quality of glue and rubber strip is on the same level, the construction level of workers is on the same level, and the same glass strip or glue is used, the process is not absolutely good or bad. Limited impact and industry differentiation;

The main reason is that the construction process content is low, which is cleaner and more beautiful than glue. Any worker can press the safety factor after simple training; the worker is high, and the glass is all pressed indoors, so there is no need to go out to glue; after 3 days, it is better to replace the glass than Make glue more convenient. After removing the rubber strip and the pressing line, the glass is easy to disassemble and replace. 4 The glass outer rubber strip has been pressed on the window frame or window sash before leaving the factory, and the drain hole has been opened in advance, so there is no need to worry about the outer glass waterproof caused by leakage;

However, China, our motherland, has a vast territory and great cultural differences between east, west, north and south. As a result, students seem to have some differences in enterprises. For example, in areas where typhoons often log in, the degree of development of adhesive tape technology research and insurance may not be enough. Glass is easy to move to the indoor side under strong winds. It is suggested that the outdoor side should be glued more firmly. The north is cold, the gluing method is not as reliable as the service life of the adhesive strip. Do you see the shape and material of many adhesive strips affecting the performance of doors and windows?

With the development and progress of the door and window engineering industry in our country, the material, type and shape of the rubber strip are also developing social progress.

And optimize these, is around the door and window products better sealing performance, extend the service life of the two goals.

If the door and window sealing strip is designed to be soft and hard co-extruded, it will have a larger contact area with the spacer strip and a better sense of operation. The long tail rubber strip is used on the glass side to improve the heat insulation of the glass edge. Some rubber strips will expand when exposed to water to improve the sealing performance of window sash in rainy days. When buying doors and windows, how to look

Look at the chapter on how to choose the ideal product structure for doors and windows with tape:

Select strip material. According to everyone's feedback, the problem is not serious. Most businesses use popular EPDM and thermoplastic composite tape (TPE), both of which are good materials. It can have a lasting effect.

However, PVC adhesive tape, which has been widely criticized, is now in a situation where one foot has stepped into the social elimination zone. For the sake of safety, one can also not ask the merchant about the material of the adhesive tape.

Number of sealing channels. In other cases, under the same premise, the three sealing products are relatively better than the two sealing effects. Cicada believes that there are three budget options for home doors and windows, and the general traditional second family is sufficient for use.

Three choices of adhesive strip brands. Look at the shape of the tape. After a section of different plastic shapes, is based on the functional extension of the material, the corresponding role and function still exist, if you choose to buy high demand products, you can also take such a review.

Look at the overlap of the five tapes. That is, the contact area between the rubber strip and the window sash when the window is locked. There is no doubt that the greater the tape overlap, the better the sealing effect.
