Product Description
Promotion Price China VIG Vacuum Insulated Glass Double Glazing Low-e Tempered Vacuum Insulating Glass
🌡️
Thermal Insulation
U-Value as low as 0.4W/(Square meters·K). A 8.3 mm thick glass has better thermal insulation effect than a 1.5m thick brick wall.
🔊
Noise Reduction
With its weighted sound reduction index exceeding 36dB, it makes rooms in downtown quiet like a library.
❄️
Free of Condensation
Free of condensation even when the temperature falls below -70 °C, maintaining exceptional transparency for buildings and freezers.
🛡️
Tempered Safety
Surface stress and granularity meet tempered glass standards, with wind resistance up to ±7200Pa.

Frequently Asked Questions
Q1: What is the thermal insulation performance (U-value) of LandVac?
The U-value is as low as 0.48 W/(m²K) for standard LandVac and 0.42 W/(m²K) for triple glazing, which is 2 to 4 times better than regular insulated glass.
Q2: Is the vacuum insulated glass fully tempered?
Yes, it uses low-temperature sealing technology that allows the glass to retain its tempered safety features, with surface stress exceeding 90MPa.
Q3: How effective is it for noise reduction?
It has a weighted sound insulation measurement of up to 39 dB, effectively blocking medium and low-frequency traffic and construction noises.
Q4: Does condensation form on the glass surface?
No, the high vacuum interspace eliminates condensation even when outdoor temperatures fall as low as -40°C.
Q5: What is the expected lifespan of the product?
The life expectancy exceeds 25 years thanks to flexible edge sealing technology and built-in high-efficiency getter materials.
Q6: What are the maximum and minimum dimensions available?
The maximum dimension is 1500 x 2500 mm, and the minimum size is 300 x 300 mm.
