Insulated glass doors and windows are gradually becoming the new favorite of home decoration with its excellent insulation and sound insulation. But as long as you go shopping in the building materials market, people will find that there are many types 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, etc., from 200 yuan / square The rice is more than 1,000 yuan / square meter, it is dazzling.
Discrimination of false hollow and true hollow: According to experts, regular glass doors and windows must be sealed with two sealing strips, vacuumed in the middle, and filled with inert gas. Such a structure makes the true insulating glass door and window have good sound insulation performance. In the past, many cheap and inferior "hollow" glass doors and windows simply glued the two pieces of glass together and did not undergo the above treatment, so there is no sound insulation effect unique to the insulating glass.
How to distinguish fake "hollow" and true hollow when purchasing:
First, is the glass sealed? Many of the fake glass doors and windows are bonded with black PVC foam strips and have no sealing effect. The true insulating glass doors and windows are bonded to the glass with a special sealing strip to ensure absolute sealing.
Second, there is an aluminum spacer between the two pieces of glass. There are many venting holes on the aluminum spacer. The desiccant is placed inside, which can absorb the moisture in the gas and prevent the fog from appearing when the glass doors and windows are heated. The phenomenon, while the fake "hollow" glass does not have these devices.
Third, test the sound insulation of doors and windows in the field. The sound insulation effect of the true hollow glass doors and windows is very good, and the sound insulation effect of the fake "hollow" doors and windows is very general.
