Product Description

LandVac Vacuum Glass Insulated LOW-E Glass Noise-Control Glass

Thermal Insulation

U-Value as low as 0.4W/(m²·K). A 8.3 mm thick LandVac has better thermal insulation effect than a 1.5m thick brick wall.

Noise Reduction

Weighted sound reduction index exceeds 36dB, making rooms in downtown as quiet as a library.

Free of Condensation

Remains clear even below -70 °C. Ultra-low dew point allows transparency maintenance in buildings and freezers.

Tempered Safety

Meets tempered glass standards with wind resistance up to ±7200Pa and surface stress exceeding 90MPa.

Core Advantages

Energy Saving: Thermal insulation is 2 to 4 times better than insulated glass and 6 to 10 times than single pane glass. High vacuum interspace eliminates gas heat transfer.

Super Long Life: Expectancy exceeds 25 years. Flexible edge sealing materials prevent failures caused by high temperature differences.

Five Key Technologies
Low Temperature Sealing Technology
Retains safety features of tempered glass with surface stress exceeding 90MPa.
Flexible Edge Sealing Technology
Higher thermal resistance against expansion/contraction, ensuring durability.
High Vacuum Sealing-off Technology
Maintains consistent high vacuum between layers for remarkable durability.
Flat Sealing Technology
Sealing does not protrude, ensuring safe transport and elegant window mounting.
Intelligent Automation Technology
Minimizes human intervention, improving product quality and performance consistency.
Applications

Architecture

Doors, windows, curtain walls, and skylights for commercial, residential, and green buildings.

Home Appliances

Ideal for freezers, wine cabinets, and display cases due to condensation-free properties.

Transportation

Flat window materials for automobiles, high-speed rail, aircraft, and vessels.

Frequently Asked Questions
Q1: What is the thermal insulation performance of LandVac?
LandVac features a U-value as low as 0.48 W/(m²·K), which is 2 to 4 times better than standard insulated glass and provides insulation comparable to a 1.5m thick brick wall.
Q2: Can LandVac effectively reduce noise?
Yes, with a weighted sound reduction index exceeding 36dB (and up to 39dB), it significantly blocks medium and low-frequency noises like traffic and construction.
Q3: Does the glass fog up in cold weather?
LandVac is free of condensation even when temperatures fall below -70 °C, ensuring exceptional transparency for buildings and freezers.
Q4: Is it safe for high-rise buildings?
Absolutely. LandVac is fully tempered with surface stress exceeding 90MPa, meeting international safety glass standards and resisting wind pressure up to ±7200Pa.
Q5: How long is the service life of this vacuum glass?
The life expectancy exceeds 25 years, thanks to flexible edge sealing technology and built-in high-efficiency getter materials that prevent sealing failure.
Q6: What are the thickness and weight advantages?
LandVac is significantly thinner (approx. 8.3mm) and weighs 10kg less per square meter than triple-pane insulated glass while providing superior thermal performance.
