1. The insulating glass can be filled with argon gas, which can reduce the U value of the insulating glass and increase the heat insulation of the insulating glass; 2. The insulation performance reaches K=2.2W/(m2 • K); Can be made of single glass or hollow glass; 3. Double-sided tempered insulating glass, better sound insulation and safety performance. The hollow configuration can be matched with the lattice decoration, so that the overall effect is out of monotonous and the style is changeable; 4. Excellent strength, heat insulation and sound insulation performance, meeting the engineering needs of 75% of building energy efficiency;
