LandVac Energy Saving Glass (Low-E) Low E Vacuum Insulated Solar Control Coated Glass
U-Value as low as 0.4W/(m²·K). An 8.3 mm thick LandVac has better thermal insulation effect than a 1.5m thick brick wall.
With its weighted sound reduction index exceeding 36dB, LandVac makes rooms in downtown quiet like a library.
Free of condensation even when the temperature falls below -70 °C, maintaining exceptional transparency for buildings and freezers.
LandVac® is an all-new generation tempered vacuum insulated glass. Using exclusive low-temperature sealing technology, the product has outstanding features in thermal and sound insulation while retaining the strength and safety of the glass at a high level. It leads the trend in green building and upscale home appliances.
| Product Type | Structure | Thickness (mm) | U-value (W/m²K) | SHGC | Sound Isolation (dB) |
|---|---|---|---|---|---|
| LandVac | 4TL+0.3V+4T | 8.3 | 0.48 | 0.49 | 39 |
| Triple Glazing (Plus Insulated) | 4T+12A+4TL+0.3V+4T | 24.3 | 0.42 | 0.45 | 42 |
* T-Tempered clear; TL-tempered Low-E; V-vacuum space; A-air space. Data calculated per U.S. ASHRAE standards.
Surface stress exceeds 90MPa, meeting safety glass standards while retaining impact resistance features.
Thermal performance 2-4 times better than insulated glass and 6-10 times better than single pane glass.
Retains the safety features of tempered glass by preventing annealing during the sealing process, maintaining stress above 90MPa.
Uses materials with high resistance to thermal expansion, preventing failure caused by extreme temperature differences.
Maintains high-degree vacuum consistency between layers for long-term durability and performance.
Non-protruding edges for safe transport and intelligent automation to ensure consistent quality.
The manufacturing center utilizes a continuous vacuum glass production line that minimizes human intervention. Products meet global standards including ANSI Z97.1, ift Rosenheim testing, and RoHS directives.
