Insulating glass doors and windows are really difficult to distinguish? Teach you to "five look" to understand the doorway

[China Glass Net] Insulating glass is widely used in home decoration because of its warm and soundproof effect. However, the quality of insulating glass on the market is uneven, and how to purchase it becomes a problem.

Regular hollow glass doors and windows are to seal two pieces of glass with a sealing strip, then vacuum the middle and fill with inert gas. Such a structure makes the true insulating glass door and window have good sound insulation performance. However, many inexpensive and inferior insulating glass doors and windows are only glued together with two simple glass pieces, and have not been treated as described above, so there is no such sound insulation effect that is unique to insulating glass.

Is it so difficult to buy hollow glass? Let Xiaobian teach you "five look" and understand the doorway.

1. See if there are many sealed hollow glass doors and windows. The two pieces of glass are bonded with black PVC foam strips, and there is no sealing effect. Moreover, the real hollow glass door and window is bonded with glass by a special sealing strip, which can guarantee the sealing. There is an aluminum spacer between the two pieces of glass, and there are many venting holes on the aluminum spacer. The desiccant is placed inside, which can absorb some moisture in the gas to prevent fogging after the glass door and window are heated. The phenomenon, and there is no such equipment in the fake insulating glass.

2. Look at the appearance of high-quality profiles that look smooth, fine, clean, uniform color, no cracks, air bubbles; no weld breakage at the weld; hardness is sufficient, the surface of the profile is not broken with a hammer. Inferior profiles are not uniform in color, and there are bubbles and impurities. When they are hit with a hammer, they will rupture, and even if they are pinched by hand, they will be deformed. The consumer can observe the glass from the side, the glass is flat, there is no color difference, the article is seen through the glass, and the article is not deformed, which is a qualified product.

3. Look at the quality of auxiliary materials. The quality of plastic glass hollow glass door and window accessories is also very important. The auxiliary materials are mainly sealing tops and sealing strips. The hair on the high-quality sealing tops should be long, tidy, tight and elastic. It 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. The surface of high-quality strips should be smooth, the edges should be neat and elastic, and the hand should be kept by hand. Insulating glass doors and windows are sealed with high-quality strips to ensure a good sealing condition for a long time. Otherwise, after three or five years, the air enters the hollow glass doors and windows, and the insulation and sound insulation of the doors and windows will be affected.

4. Look at the quality of the quality of the hollow glass doors and windows using high-quality profiles, such as the well-known conch profiles, green profiles, etc., while the inferior hollow glass doors and windows use low-grade profiles, and some even the secondary recycling profiles (Appearance of a film with a well-known profile).

5 look at the hardware accessories hardware accessories to see the quality of hardware accessories, but also help to judge the quality of hollow glass doors and windows. For example, metal materials such as hinges and door locks should be treated with anti-corrosion treatment, such as galvanizing, chrome plating, spraying, or stainless steel. Hinge and the like should be designed to prevent deformation of doors and windows. The door lock should use a multi-lock lock with good anti-theft effect.
