Hollow glass doors and windows are becoming the new darling of home decoration with their excellent thermal insulation and sound insulation. But as long as they stroll in the building materials market, people will find that the wide range of insulating glass doors and windows, although the appearance of white plastic frame, the middle strip and glass, but the price is divided into threes and nines and so on, from 200 yuan / square Much to 1000 yuan / square meter has dazzling. The identification of false hollows and true hollows: According to experts, regular hollow glass doors and windows must first be sealed with two pieces of glass with sealant strips, evacuated in the middle and then filled with inert gas. This structure makes real hollow glass doors and windows have good sound insulation and heat insulation properties. In the past, many inexpensive, low-quality "hollow" glass doors and windows simply glued the two pieces of glass together and did not undergo the above-mentioned treatment. Therefore, there was no sound insulation effect unique to insulating glass. Consumers can distinguish fake “hollow†and true hollow from the following three aspects when purchasing: First, see if there is aluminum spacer There are many vent holes in the aluminum partition bar, inside the desiccant, can absorb the moisture in the gas to prevent the phenomenon of “fog and fog†after the glass doors and windows are heated, and the fake “hollow†glass does not have these devices. Second, look at profile quality High-quality hollow glass doors and windows use high-quality profiles, such as domestic well-known Conch profiles, Green profiles, etc., while low-quality hollow glass doors and windows use low-grade profiles, and some even move hands and feet of secondary recycling profiles (appearance Profile film). Third, look at the appearance The high-quality profiles look smooth, smooth, clean, uniform in color, free from cracks, and bubbles; there is no cracking and welding at the welds; the hardness and thickness are sufficient, and no cracking occurs on the surface of the profile with a hammer. The poor quality of the color of the profile, there is bubble impurities, with a hammer hit the crack will appear, or even deformed by hand. Consumers can observe the glass from the side, the glass is flat, there is no color difference, the article is seen through the glass, the article is not deformed, is a qualified product. Fourth, look at hardware accessories The identification of hardware accessories to see the quality of hardware accessories, but also help determine the quality of hollow glass doors and windows. For metal materials such as hinges and door locks, the surface should be treated with anti-corrosion treatment such as galvanizing, chrome plating, spraying, or made of stainless steel. Hinge, etc. should be designed to prevent deformation of doors and windows. Door locks use as many anti-theft locks as possible. Fifth, see the quality of auxiliary materials The quality of plastic hollow glass doors and windows is also critical. The auxiliary materials are mainly sealed tops and sealant strips. The wool on the top quality seal top should be neat, tight, and flexible. It can be effectively waterproof and dustproof. There is a bottom plate between the two tops, which can prolong the service life of the tops. The sealant strip is also very important. The surface of the high-quality stripe should be smooth, neat and flexible, and it should be pulled continuously by hand, and it should be basically restored after releasing it. Hollow glass doors and windows are sealed with high-quality rubber strips, which can ensure good sealing conditions for a long time. Otherwise, air enters hollow glass doors and windows after three to five years, and the thermal and acoustic performance of doors and windows will be affected. >>> Links: Common sense for purchasing and using insulating glass Building materials, doors, windows, hardware, glass, doors, prices, building materials, market decoration, design, stainless steel glass door, glass door Car Polisher,Car Wax,Car Wax Polish,Mini Polisher Foshan SUMEITE Grinding Technology Co.,Ltd , https://www.aedetail.com
