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 reporter specifically asked the industry experts to identify five advantages and disadvantages of insulating glass doors and windows. 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, is the glass sealed? Many pieces of fake glass doors and windows are glued with black PVC foam strips and have no sealing effect. The real hollow glass doors and windows are made of special sealing strips that adhere to the glass and guarantee absolute sealing. Second, there is an aluminum spacer between the two glass sheets of the insulating glass. There are many vent holes in the aluminum spacers. Inside, a desiccant is placed to absorb the moisture in the gas and prevent the “fog and fog†from appearing after the glass doors and windows are heated. The phenomenon of false "hollow" glass without these devices. Third, field testing of the sound insulation of doors and windows. True hollow glass doors and windows have a very good soundproofing effect, while false “hollow†doors and windows have very good soundproofing effects. High quality hollow glass doors and windows are made of high quality profiles, such as domestic famous conch profiles, Green profiles, etc., while low quality hollow glass doors and windows use low profile materials, and some even move the secondary recycling profiles ( The appearance of the film is affixed to well-known profiles, shoddy.) The high-quality profiles look smooth, smooth, clean, and uniform in color; there are no cracks or bubbles; there is no cracking and welding at the welds; the hardness and thickness are sufficient, and the surface of the profile is not broken 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. In addition, there are also differences in the quality of the steels installed in the profiles. The good inch steel thickness is 1.2mm or more, and the inch steel used in inferior profiles is often not thick enough. There are even black heart merchants who use wood in profiles to trick consumers. In addition, profiles have multiple chambers and single chambers. The multi-cavity profile consists of a main cavity (installed in steel) and multiple small cavities. The insulation and drainage performance is good, while the single-cavity profile does not have thermal insulation and drainage considerations. Glass quality discriminates the difference of the glass is relatively small, does not have the impurity bubble, the surface smooth glass is the qualified product. 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. 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 the deformation of doors and windows; door locks, as much as possible theft effect locks. The quality of auxiliary materials to identify the quality of plastic hollow glass doors and windows auxiliary material is also very critical. The auxiliary materials are mainly seal tops and sealant strips. The wool on the top quality seal top should be neat and compact, tight and elastic, and 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 will enter the hollow glass doors and windows after 35 years, and the heat insulation and sound insulation performance of doors and windows will be affected.
