4+0.3+4 Double Glazing / Vacuum Insulated Glass / VIG Glass
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 downtown rooms as quiet as a library.
No condensation even below -70°C. Maintains exceptional transparency in extreme cold environments.
Surface stress meets tempered glass standards; wind resistance up to ±7200Pa for maximum safety.

* T-Tempered clear; TL-tempered Low-E; V-vacuum; A-air space. Data calculated per U.S. ASHRAE standards.
By adopting low-temperature sealing technology, LandVac retains the safety features of tempered glass. Surface stress exceeds 90MPa, meeting international safety glass standards.
Eliminates gas heat transfer. Using high-performance Low-E coating, it suppresses radiation heat transfer, making it 2 to 4 times more efficient than standard insulated glass and 6 to 10 times more than single pane glass.
| Low Temp Sealing | Retains surface stress exceeding 90MPa, preserving the strength of tempered glass during the sealing process. |
| Flexible Edge Sealing | Uses materials with high resistance to thermal expansion, preventing sealing failure due to outdoor/indoor temperature differences. |
| High Vacuum Tech | Sealed in a UHV chamber to maintain consistent high-degree vacuum for long-term durability. |
| Flat Sealing | Sealing does not protrude above the glass surface, allowing for safe transportation and elegant mounting. |
LandVac has been approved by authoritative third parties. Results show thermal insulation at the highest national level (Level 10) and sound insulation at Level 4.
A: LandVac offers 2 to 4 times better thermal insulation (U-value as low as 0.48) and superior noise reduction in a much thinner and lighter profile.
A: Yes, it is fully tempered. Using low-temperature sealing technology, the glass retains its safety characteristics with surface stress exceeding 90MPa.
A: No. The high vacuum interspace eliminates condensation even when outdoor temperatures fall as low as -70 °C.
A: The expected lifespan exceeds 25 years, thanks to flexible edge sealing and high-efficiency getter materials that sustain vacuum performance.
A: It is highly effective against traffic and construction noise, with a weighted sound insulation measurement of up to 39 dB.
A: The maximum dimension is 1500mm x 2500mm, with a minimum size of 300mm x 300mm.
