Vacuum Insulating Glass (VIG)
Designed to maximize the benefits of vacuum insulation by combining advanced materials and cutting-edge manufacturing techniques. Made of low-emissivity coated tempered glass, high-performance desiccants, and lead-free alloy flexible solder, VIG offers exceptional thermal insulation while staying transparent—a great fit for modern architecture and energy-efficient building systems.
VIG is sealed in a high-vacuum environment, unlike conventional insulated glass, therefore guaranteeing exceptional thermal performance without requiring air extraction apertures. Ideal for ultra-thin, energy-efficient windows, this creative design lowers air leakage and provides a degree of insulation equivalent to, or even better than, walls with far thicker insulating layers.
What the Features of Vacuum Insulating Glass (VIG)
- Low-E coated glasses
- Polymer structure sealing layer
- Alloy vacuum sealing layer
- Micro strut (0.5mm)
- Tempered glass
- Degasser
- Lead-free alloy sealing. Sealed with lead-free alloy flexible solder for durability and environmental safety.
- No air extraction port. Double-sealed for superior high-vacuum performance, eliminating air leakage and improving insulation efficiency.
- Exceptional thermal efficiency. With a heat transfer coefficient comparable to walls, VIG acts as transparent ultra-thin 'walls' in architectural applications, offering optimal insulation without compromising aesthetics.
