LOW-E Double Vacuum Glass 6.3mm 8.3mm 10.3mm with 0.3mm Vacuum Gap for Windows and Curtain Walls
Vacuum glass is manufactured by sealing two flat glass panes around the edges, evacuating the 0.3mm gap between them, and sealing the exhaust hole. At least one pane features low-emissivity coating for enhanced thermal performance.

Note: Above data are for reference only. Parameters for specific products require separate calculation.
U value as low as 0.48W/(m·K). The 8.3mm thick vacuum glass provides superior insulation, exceeding 1.5m thick brick walls. Thermal performance is 2-4 times better than insulating glass and 6-10 times better than single glass.
Weighted sound insulation reaches 39 decibels, significantly higher than standard insulating glass at approximately 28 decibels.
No gas inside the vacuum chamber eliminates internal condensation and fogging issues.
