Customized Soundproof Tempered Clear Vacuum Insulated Glass
LandVac® is an all new generation tempered vacuum insulated glass developed with independent intellectual property rights. Using exclusive low temperature sealing technology, the product features outstanding thermal and sound insulation while retaining high levels of strength and safety.
U-Value as low as 0.4W/(m²·K). An 8.3 mm thick LandVac has better thermal insulation than a 1.5m thick brick wall.
Weighted sound reduction index exceeds 36dB, making rooms in busy downtown areas as quiet as a library.
Remains free of condensation even when temperatures fall below -70 °C, maintaining exceptional transparency.
Surface stress meets 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 (LandVac Plus) | 4T+12A+4TL+0.3V+4T | 24.3 | 0.42 | 42 |
* T-Tempered clear glass; TL-tempered Low-E glass; V-vacuum space; A-air space.
* Max. Size 1500x2500mm; Min. Size 300x300mm. Performance data calculated per U.S. ASHRAE standards.
Thermal insulation is 2 to 4 times better than standard insulated glass and 6 to 10 times better than single pane glass. It meets international passive house requirements for windows and doors.
| Low Temp Sealing | Surface stress exceeds 90MPa, perfectly retaining the safety features of tempered glass against impact. |
| Flexible Edge Sealing | Uses flexible materials with high thermal resistance against expansion/contraction for extreme durability. |
| High Vacuum Sealing | Sealed in a UHV chamber to maintain consistent high vacuum levels between layers. |
| Flat Sealing | Sealing does not protrude, ensuring elegant aesthetics and safe transportation. |
| Intelligent Automation | Continuous production line minimizes human intervention for superior quality consistency. |
Our products have been approved by authoritative third parties. Results show thermal insulation performance reaches Level 10 (highest national standard) and sound insulation comparable to regular triple glazing.
