Tempered Clear Vacuum Insulated Glass
LandVac® is a new generation tempered vacuum insulated glass developed with independent intellectual property rights. Using exclusive low-temperature sealing technology, the product offers outstanding thermal and sound insulation while maintaining high safety standards.
🔥
Thermal Insulation: U-Value as low as 0.4W/(m²·K). An 8.3mm thick LandVac outperforms a 1.5m thick brick wall in insulation.
🔇
Noise Reduction: Weighted sound reduction index exceeds 36dB, making urban rooms as quiet as a library.
❄️
Free of Condensation: Maintains transparency even below -70 °C, ensuring clarity in extreme cold or freezers.
Inner Structure & Advantages
High Safety Standards
LandVac is fully tempered. The surface stress exceeds 90MPa, meeting international safety glass standards for impact resistance.
Superior Soundproofing
Effectively blocks medium and low-frequency noise like traffic and construction. An outdoor noise of 75dB can be reduced by 39dB.
Wide Applications
Architecture: Doors, windows, curtain walls, skylights, and passive houses.
Home Appliances: Freezers, wine cabinets, and display cases.
BIPV: Solar photovoltaic buildings with sloped installations.
Transportation: High-speed rail, aircraft, and vessels.
Agriculture: Modern greenhouse farming.
Scientific Research: Low-temperature observation windows.
Production & Certification
Approved by authoritative third parties including ANSI, ATI, ift, and RoHS. Thermal insulation reaches the highest Level 10 of national standards.
Frequently Asked Questions
Q1: What is the thermal insulation performance of LandVac?
LandVac offers a U-value as low as 0.48 W/(m²·K), which is 2 to 4 times better than standard insulated glass and significantly more efficient than brick walls.
Q2: Is this glass safe for high-rise buildings?
Yes, LandVac is fully tempered vacuum insulated glass. Its surface stress exceeds 90MPa, meeting safety glass standards for wind resistance and impact.
Q3: How effective is it at soundproofing?
It has a weighted sound reduction index exceeding 36dB, effectively blocking traffic and construction noise, particularly at medium and low frequencies.
Q4: Does LandVac prevent window condensation?
Yes, it remains free of condensation even when outdoor temperatures fall below -40°C, ensuring high transparency in all weather conditions.
Q5: What is the life expectancy of LandVac?
The life expectancy exceeds 25 years thanks to its flexible edge sealing and built-in high-efficiency getter materials that prevent sealing failure.
Q6: How heavy and thick is the product?
A standard LandVac is approximately 8.3mm thick and weighs about 20-28 kg per square meter, making it much lighter and thinner than triple-pane insulated glass.
