hollow glass doors and windows are gradually becoming the new favorite of home decoration because of their excellent heat preservation and sound insulation effects. However, as long as you stroll around the building materials market, people will find that there are a wide variety of hollow glass doors and windows. Although the appearance is white plastic steel frame, middle trim strip and glass, the price is divided into three or six grades, ranging from more than 200 yuan/square meter to more than 1000 yuan/square meter, which is dazzling

discrimination between false hollow and true hollow: according to experts, for regular hollow glass doors and windows, first seal the two pieces of glass with sealant strips, vacuum the middle, and then fill in inert gas. Such a structure makes the real insulating glass doors and windows have good sound insulation and heat insulation performance. Many cheap and inferior "hollow" glass doors and windows just simply glue the two pieces of glass together without the above treatment, so they do not have the sound insulation and heat insulation effect unique to hollow glass

when shopping, consumers can distinguish between false "hollow" and true hollow from each other from the following three aspects:

first, see whether there are aluminum spacer strips

there are many air holes on the aluminum spacer strips, which are placed with desiccant, which can absorb the moisture in the gas and prevent the phenomenon of "misty" after the glass doors and windows are heated, while the false "hollow" glass does not have these devices

second, look at the quality of profiles

high quality insulating glass doors and windows use high-quality profiles, such as conch profiles and green profiles, which are relatively well-known in China, while low-grade profiles are used for low-quality insulating glass doors and windows, and some even secondary recycled profiles (films pasted with well-known profiles externally)

third, look at the appearance

the high-quality profile looks smooth and delicate on the surface, flat and clean, uniform in color, and free of cracks and bubbles; There is no fracture and welding at the welding position; The hardness and thickness are enough to knock the surface of the profile with a hammer without cracking. However, the color of inferior profiles is uneven, with bubbles and impurities. Knocking with a hammer will cause cracking, and even deformation when pinched by hand. Consumers can observe the glass from the side. The glass is flat and has no color difference. Looking through the glass, the article has no deformation, which is a qualified product

fourth, look at the identification of hardware accessories

seeing the quality of hardware accessories is also helpful to judge the quality of hollow glass doors and windows. For example, the surface of metal materials such as hinges and door locks should be subject to anti-corrosion treatment, such as galvanizing, chrome plating, spraying, or made of stainless steel materials. Hinges shall be designed to prevent deformation of doors and windows. Try to use multi-point lock with good anti-theft effect for door lock

fifth, look at the quality of auxiliary materials

the quality of auxiliary materials for plastic steel hollow glass doors and windows is also very critical. The auxiliary materials are mainly sealing wool tops and sealant strips. The wool on the high-quality sealing wool tops should be neat, tight and elastic, which can effectively prevent water and dust. There is a bottom plate between the two wool tops, which can prolong the service life of the wool tops. Sealant strips are also very important. The surface of high-quality strips should be smooth, with neat edges and elasticity. They should be pulled continuously by hand and basically return to the original state after release. Insulating glass doors and windows are sealed with high-quality rubber strips, which can ensure a good sealing state for a long time. Otherwise, if the air enters the hollow glass doors and windows after three to five years, the heat insulation and sound insulation performance of the doors and windows will be affected
