Energy Saving Glass (Low-E) Vacuum Insulated

Landvac Energy Saving Glass

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 downtown rooms quiet like a library.

Free of Condensation: Maintains transparency even below -70 °C.

Tempered Safety: Surface stress meets tempered glass standards, wind resistance up to ±7200Pa.

Core Advantages

Seven Advantages

Tempered Safety Glass

Adopting low temperature sealing technology, it perfectly retains the safety features of tempered glass against impact. Surface stress exceeds 90MPa.

Tempered Safety

Noise Reduction Performance

Effectively blocks medium and low frequency penetrating noises. Outdoor noise of 75 dB can be reduced by 39 dB.

Noise Reduction

Super Long Life Span

Life expectancy exceeds 25 years. Flexible edge sealing materials prevent failure caused by temperature differences and material aging.

Innovative Technologies

Low Temperature Sealing Retains safety features of tempered glass by integrating key vacuum and tempering solutions.
Flexible Edge Sealing Adopts materials with higher thermal resistance against expansion or contraction.
High Vacuum Sealing Maintains consistent high vacuum between layers in a UHV chamber.
Flat Sealing Tech Sealing does not protrude, ensuring easy transportation and elegant mounting.

Wide Range of Applications

Applications
  • Architecture: Doors, windows, curtain walls, and skylights for green buildings.
  • Home Appliances: Ideal for freezers, wine cabinets, and display cases.
  • BIPV: Solar photovoltaic buildings with thermal insulation requirements.
  • Transportation: Flat window materials for high-speed rail, aircraft, and vessels.

Production & Qualification

Production Center
Qualification

The tempered vacuum insulated glass has been approved by authoritative third parties. Results show thermal insulation performance reaches the highest national standard (Level 10) and sound insulation reaches Level 4.

Cases

Frequently Asked Questions

Q1: What is the thermal insulation performance of LandVac? LandVac offers exceptional thermal insulation with a U-value as low as 0.48 W/(m²·K), which is 2 to 4 times better than traditional insulated glass.
Q2: Is this vacuum glass fully tempered? Yes, LandVac is a fully tempered vacuum insulated glass. Using exclusive low-temperature sealing technology, it retains the high strength and safety features of tempered glass.
Q3: How does it perform in noise reduction? It effectively blocks sound transmission with a weighted sound insulation measurement of up to 39 dB, significantly better than regular laminated glass.
Q4: Will condensation form on the glass surface? LandVac effectively eliminates dew condensation between layers. The interior surface remains free of condensation even when outdoor temperatures fall to -40 °C.
Q5: What is the estimated life span of the product? The life expectancy exceeds 25 years, thanks to flexible edge sealing technology and built-in high-efficiency getter materials that sustain performance over time.
Q6: What are the typical applications for vacuum glass? It is widely used in green building architectures (windows, doors, skylights), home appliances (freezers, wine cabinets), BIPV, and transportation vehicles.
