Product Overview
Laminated Decoration Soundproof / Noise Reduction Vacuum Insulated Glass for Window provides a new generation of tempered vacuum insulated glass. Using exclusive low-temperature sealing technology, the product offers outstanding features in thermal and sound insulation while retaining high levels of glass strength and safety.
🌡️
Thermal Insulation
U-Value as low as 0.4W/(m²·K). A 8.3 mm thick glass has better thermal insulation than a 1.5m thick brick wall.
🔇
Noise Reduction
Weighted sound reduction index exceeds 36dB, making busy city rooms as quiet as a library.
❄️
Free of Condensation
Maintains transparency even when temperatures fall below -70 °C, ensuring no dew point issues.
🛡️
Tempered Safety
Wind resistance up to ±7200Pa. Meets tempered glass standards for impact and surface stress.

Inner Structure & Seven Advantages
✅ Energy Saving: 2 to 4 times better thermal insulation than standard insulated glass and 6 to 10 times better than single pane glass.
✅ Noise Barrier: Effectively blocks medium and low frequency penetrating noises like traffic and construction.
✅ Super Long Life: Life expectancy exceeds 25 years thanks to flexible edge sealing and high-efficiency getter materials.
✅ High Flexibility: Thinner and lighter (10 kg less per sqm) than triple-pane insulated glass.
Core Technologies
Low Temperature Sealing: Retains safety features of tempered glass with surface stress exceeding 90MPa.
Flexible Edge Sealing: Higher resistance against thermal expansion and contraction compared to traditional fragile materials.
High Vacuum Sealing: Maintains consistent high degree vacuum in a UHV chamber.
Flat Sealing Technology: Sealing does not protrude, ensuring elegant aesthetics and safe transportation.
Application Fields
Architecture: Commercial & residential windows, curtain walls, and skylights.
Home Appliances: Freezers, wine cabinets, and display cases.
BIPV: Solar photovoltaic buildings with sloped installations.
Transportation: Windows for high-speed rail, aircraft, and vessels.
Qualification & Display
Frequently Asked Questions
Q1: What is the thermal insulation performance of LandVac?
LandVac has a U-value as low as 0.48 W/(m²·K), which is 2 to 4 times better than traditional insulated glass and offers performance similar to a 1.5m thick brick wall.
Q2: How does it perform in terms of noise reduction?
It effectively blocks medium and low-frequency noises with a weighted sound insulation index of 39 dB, significantly higher than the 29 dB typical of regular laminated glass.
Q3: Is vacuum glass safe if it breaks?
Yes, it is fully tempered safety glass. The surface stress exceeds 90MPa, meeting international safety glass standards for impact resistance.
Q4: Will condensation form between the layers?
No. The high vacuum interspace eliminates condensation even when the outdoor temperature drops to -40 °C or even -70 °C.
Q5: How long is the service life of this vacuum glass?
The life expectancy exceeds 25 years, supported by flexible edge sealing technology and built-in high-efficiency getter materials that prevent material aging.
Q6: Is it much heavier than standard glass?
On the contrary, LandVac is thinner and lighter. Compared to triple-pane glass, it is about one-sixth of the thickness and weighs 10 kg less per square meter.
