Key Advantages
🔥
Thermal Insulation: U-Value as low as 0.4W/(㎡·K). An 8.3 mm thick LandVac provides better insulation than a 1.5m thick brick wall.
🔇
Noise Reduction: Weighted sound reduction index exceeds 36dB, effectively blocking traffic and construction noise.
❄️
Free of Condensation: Remains condensation-free even below -70°C, maintaining exceptional transparency for buildings and freezers.
🛡️
Tempered Safety: Surface stress exceeds 90MPa, meeting tempered glass standards with wind resistance up to ±7200Pa.

Frequently Asked Questions
Q1: What is the thermal insulation performance of LandVac?
LandVac features a high vacuum interspace that eliminates gas heat transfer. With Low-E coating, the U-value is reduced to 0.48 W/(m²·K), which is 2 to 4 times better than standard insulated glass.
Q2: Can LandVac prevent window condensation?
Yes. The high vacuum interspace effectively eliminates dew condensation between glass layers, keeping the interior surface clear even when outdoor temperatures fall to -40 °C.
Q3: Is this glass safe for high-rise buildings?
Absolutely. LandVac is fully tempered vacuum insulated glass. Its surface stress exceeds 90MPa, meeting safety glass standards and offering wind resistance up to ±7200Pa.
Q4: How effective is it for noise reduction?
It has a weighted sound reduction index exceeding 36dB. It is particularly effective against medium and low-frequency noises like traffic and construction sounds.
Q5: What is the life expectancy of LandVac vacuum glass?
The life expectancy exceeds 25 years, thanks to flexible edge sealing technology and built-in high-efficiency getter materials that resist material aging.
Q6: How thin is LandVac compared to triple glazing?
LandVac is significantly lighter and thinner. It is approximately one-sixth the thickness of triple-pane insulated glass and weighs about 10 kg less per square meter.
