Building Window Glass Construction Curtain Wall Facade Architectural Tempered Toughened Laminated Low E Vacuum Insulated Double Glazing
U-Value as low as 0.4W/(m²·K). A 8.3 mm thick LandVac has better thermal insulation effect than a 1.5m thick brick wall.
With a weighted sound reduction index exceeding 36dB, it makes rooms in downtown quiet like a library.
Remains free of condensation even when temperatures fall below -70 °C, maintaining exceptional transparency.
Surface stress and granularity meet tempered glass standards, with wind resistance up to ±7200Pa.
| Product Type | Structure | Thickness (mm) | U-value (W/m²K) | Sound Isolation (dB) |
|---|---|---|---|---|
| LandVac | 4TL+0.3V+4T | 8.3 | 0.48 | 39 |
| Triple Glazing | 4T+12A+4TL+0.3V+4T | 24.3 | 0.42 | 42 |
1. Low Temperature Sealing: Retains safety features of tempered glass with surface stress exceeding 90MPa.
2. Flexible Edge Sealing: Higher resistance against thermal expansion and contraction, preventing sealing failure.
3. High Vacuum Sealing: Maintained in a UHV chamber for consistent degree of vacuum and durability.
4. Flat Sealing: Sealing does not protrude, ensuring safe transportation and elegant mounting.
5. Intelligent Automation: Continuous production line minimizes human intervention and ensures quality consistency.
The U-value can be as low as 0.48 W/(m²·K) for standard LandVac and 0.42 W/(m²·K) for triple glazing versions, offering insulation performance 2 to 4 times better than traditional insulated glass.
Yes, it is a fully tempered vacuum insulated glass. Using low-temperature sealing technology, it retains the safety features of tempered glass with surface stress exceeding 90MPa.
The glass has a weighted sound reduction index exceeding 36dB-39dB. It effectively blocks medium and low-frequency noises like traffic and construction sounds.
No, the high vacuum interspace eliminates dew condensation. The interior surface remains free of condensation even when outdoor temperatures fall to -40 °C or lower.
The life expectancy exceeds 25 years, thanks to flexible edge sealing technology and built-in high-efficiency getter materials that resist material aging and harsh environments.
The maximum dimension for LandVac vacuum glass is 1500 x 2500mm, with a minimum size of 300 x 300mm.
