Hollow glass doors and windows are gradually becoming the new favorite of home decoration with their excellent heat preservation and sound insulation effects. Distinguishing between false hollow and true hollow According to experts, for regular hollow glass doors and windows, two pieces of glass must be sealed with a sealing tape first, the middle must be vacuumed, and then filled with inert gas.
Distinguishing between false hollow and true hollow According to experts, for regular hollow glass doors and windows, two pieces of glass must be sealed with a sealing tape, the middle must be vacuumed, and then filled with inert gas. This structure makes the real hollow glass doors and windows have good sound insulation and heat insulation performance. Many previous cheap and inferior “hollow” glass doors and windows simply glued two pieces of glass together without the above-mentioned treatment, so there is no sound insulation and heat insulation effect that is unique to hollow glass.
Distinguishing the quality of auxiliary materials The quality of auxiliary materials is also very critical. The auxiliary materials are mainly sealing tops and sealing rubber strips. The hairs on the high-quality sealing tops should be neat, tight and elastic, and can be effectively waterproof and dustproof. There is a bottom plate between the two tops to extend the service life of the tops. Sealing strips are also very important. High-quality strips should have a smooth surface, neat edges, and elasticity. They should be hand-drawn continuously, and they will basically return to their original shape after letting go. Hollow glass doors and windows are sealed with high-quality rubber strips, which can ensure a good sealing state for a long time. Otherwise, after three to five years, air enters the hollow glass doors and windows, and the heat and sound insulation properties of the doors and windows will be affected.
But as long as you stroll around in the building materials market, people will find that there are many types of hollow glass doors and windows. Although the appearance is all alloy outer frames, middle trims and glass, the prices are divided into three or sixty-nine categories, ranging from more than 200 yuan per square meter. There are more than 1,000 yuan/square meter, which is dazzling.

Consumers can distinguish between fake "hollow" and true hollow from the following three aspects: First, whether the glass is sealed. The two pieces of glass of many fake hollow glass doors and windows are glued with black PVC foam strips, and there is no sealing effect. The real hollow glass doors and windows are glued with special sealing tape to ensure absolute sealing. Secondly, there is an aluminum partition between the two pieces of glass, and there are many vents on the aluminum partition. A desiccant is placed inside to absorb the moisture in the gas and prevent the glass doors and windows from becoming "foggy" after being heated. Phenomenon, while fake "hollow" glass does not have these devices. Finally, the sound insulation effect of doors and windows was tested on the spot. The sound insulation effect of real hollow glass doors and windows is very good, while the sound insulation effect of fake "hollow" doors and windows is very average.
