How to distinguish the true and false of insulating glass？

1.Is the glass sealed?The fake insulating glass doors and windows are bonded with two pieces of glass with black PVC foam strips and no sealing effect.The true insulating glass doors and windows are bonded to the glass with a special sealing strip to ensure absolute sealing.

2.There is an aluminum spacer between the two glass of ture insulating 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 and the fog from appearing after the glass door and window are heated.Phenomenon,whi -le fake"hollow"glass does not have these devices.

3.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.

4.Look at the appearance of profiles.The high-quality profiles book smooth,delicate,uniform in color,free from cracks and bubbles,and have sufficient hardness.The surface of the profile is not broken by the hammer.

5.Look at the sealant strip.The surface of the high-quality rubber strip should be smooth,the edg

-es shoule be neat and elastic,and it should be hand-drawn continuously,and the original shape shoule be restored after loosening the hand.

6.Look at the quality of the profile.High-quality insulating glass doors and windows use high-qua -lity profiles,such as the well-known conch profiles and green profiles in china,while the inferior hollow glass doors and windows use low-grade profiles,and some even the secondary recycling profiles with hands and feet(appearance is well-known)film of the profile.

7.Look at hardware accessories.
