High noise insulation
Good insulation effect.
Good optical performance
High wind pressure resistance
Energy saving and environmental protection
1. Whether the glass is sealed or not, good quality insulating glass uses silicone sealant for insulating glass, poor quality uses adhesive tape.
2. Test the sound insulation of insulating glass, and the sound insulation effect is excellent.
3. Check whether there are aluminium spacers between the insulating glass. Good aluminium strips have smooth appearance, no chromatic aberration, firm welding and even perforation.
4.The glass has no air bubbles, is flat, and does not exhibit deformation. It is a qualified glass.
