Hollow glass has the function of sound insulation, heat insulation and is widely used in home furnishings. However, the quality of hollow glass in the market is uneven, so how can we tell whether the hollow glass is genuine or not?

1. 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.

2. 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.

3. 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.

4. Look at the 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).

5 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.

Precautions

Insulating glass requires special care during installation to prevent air from entering the glass interlayer due to improper handling.
