insulating glass

Hollow glass is a functional building material composed of two or more layers of glass combined through a sealed structure, filled with dry air or inert gas (such as argon) in the middle to form a thermal and sound insulation layer.

Hollow glass is an ideal choice for balancing cost and performance:

Energy saving priority: choose Low-E coating+argon filling, U value can be optimized to below 1.6 and 35;

Sound insulation essential: Near the road/airport, a sandwich hollow combination is needed to increase low-frequency noise isolation by more than 7dB;

Safety scenario: Paired with tempered or fire-resistant glass to avoid the risk of self explosion 410.

When choosing, pay attention to the national standard GB/T11944 for sealing performance (dew point ≤ -40 ℃) 319. Poor quality products are prone to failure after six months
