Aluminum door and window sealing strips are divided into two types: laminated glass sealing strips and siliconized tops. Sealing strips are generally used on aluminum doors and windows. There are also special sealing strip grooves on decorative strips and aluminum doors and windows. The main function is to wear sealing strips on the decorative strips and inner sash to make the glass and frame sash closer. Ensure the sealing of doors and windows. The installation position of the sealing strip should be neat. It should not be rolled or stretched. The connector should be less than 1mm. The specifications of the sealing strip should be suitable. If the sealing strip is too large, the strip will not be pressed in. If it is too small, the sealing strip will be easily pressed. If it falls, the glass and the fan body will not be close together, and gaps will appear. Sealing strips should be non-toxic. Odorless environmental protection special sealing strip.

The installation position of siliconized tops is generally on the aluminum door and window sashes, around the frame sash or on the sealing bridge (wind block) to improve the sealing between the frame and the sash. If the size of the siliconized top is too large or the bristles are too high, it will not only be difficult to install, but also increase the resistance to movement of the window and door, especially the initial resistance at startup and the resistance at the end of cancellation are relatively large. If the specification is too small, the height of the vertical siliconized top is not high enough and it is easy to slip out of the groove, which greatly reduces the sealing performance of the (door) window. Silicified tops must be treated with aluminosilicate. The plastic steel shape that meets the standard has a vertical surface, with a smooth bottom plate and bristles. No flex, no black spots in the base plate. Bubbles. The bristles are firmly bonded to the bottom plate, the density is even, and the hair is not easy to shed.

Aluminum doors and windows have good sealing and airtightness, but what about sound insulation? Of course, leave it to the experts in sound insulation and noise reduction - insulating glass windows. Put two or more pieces of glass together with aluminum alloy spacers (which are filled with moisture-proof agent) plus the distance between corner posts, and coat the edges around the glass with butyl. Polysulfide rubber; makes it produce stationary, dry gas and has vacuum pump performance. Insulated glass windows are equipped with thermal insulation, sealing, frost protection, anti-fouling and sound insulation. A variety of excellent properties. Therefore, many customers recognize it. Good insulating glass windows should be clean inside. There is no dust. There is no water vapor.

Good doors and windows are inseparable from production and installation. Whether the specifications produced are indispensable for standardized aluminum doors and windows. The manufacturing process of production line equipment determines whether the overall performance of aluminum doors and windows is of high quality. According to the requirements, the diagonal difference of aluminum alloy doors and windows should be controlled within 2-3 mm, and there are strict process indicators and monitoring ranges. This requires certain production equipment and manufacturing processes to ensure, and highly capable employees. Team. Therefore, there is a real difference between small street workshops and reliable manufacturers producing plastic steel windows. It is made in three parts and assembled in seven parts. If you do not pay attention to the installation specifications, the aluminum alloy doors and windows may be deformed. The thermal coefficient of plastic steel profiles seems to be 6 times that of steel. Therefore, a deformation gap must be left between the window and the wall to prevent thermal expansion and contraction or slight foundation settlement of the house, which may deform the aluminum alloy doors and windows. At the same time, to ensure moisture protection. Insulated. For noise reduction and sound insulation performance, the deformation joints must be filled with rubber and then sealed with sealant. The cost of various materials is high, and the quality gap is huge. Shoddy and shoddy products must be resolutely eliminated during installation.
