With rising building energy-efficiency standards, the insulating glass market is experiencing explosive growth. The latest industry data shows that my country's insulating glass production increased by 23% year-on-year in the first half of 2024, with Low-E energy-saving products accounting for over 40%, becoming the standard choice for new residential and commercial buildings.
Technological Advantages Drive Popularization
Insulating glass, with its unique double-layer (or multi-layer) structure, creates a dry airtight layer between the glass panes, achieving three core functions:
1. Thermal Insulation and Energy Saving: Blocks over 70% of heat in summer, reducing air conditioning energy consumption.
2. Sound Insulation and Noise Reduction: Effectively reduces outdoor noise by 35 decibels.
3. Anti-condensation: Maintains transparency even with a 60°C temperature difference between indoor and outdoor temperatures.
Innovative applications continue to emerge.
A Hebei company has launched magnetically controlled louver insulating glass, achieving "two uses in one glass." Using an external magnetic device to adjust the internal louvers, it meets the dual needs of light and privacy. A Shanghai manufacturer has developed fire-resistant insulating glass that has passed a 90-minute fire test, providing a new safety solution for public buildings such as hospitals and schools.
Industry Observation
"Under the dual carbon goals, the penetration rate of energy-saving glass will accelerate," an expert from the China Architectural Glass Association noted. "Currently, the growth rate of high-performance products such as triple-glazed, double-cavity, and vacuum-laminated glass is twice that of ordinary insulating glass. Technological upgrades are key to competitiveness."
