Strategic Keywords: How VIG works | condensation free windows | Passivhaus glass | slim acoustic glass
VIG creates a permanent vacuum cavity (10⁻³Pa) between two ultra-clear glass panes using aerospace sealing tech, supported by micro-pillar matrix (3-4 pillars/cm²). Core breakthroughs:
✅ Ultra Insulation: U-value 0.07-0.12 BTU
✅ Slim Profile: 0.25"-0.47" total thickness
✅ Lifespan Guarantee: ＞30yr vacuum retention (SGS test)
Tech: 3.3 borosilicate glass + 0.012" metal sealing edge + 10⁻⁶ torr vacuum
