Frequently Asked Questions
Q1: What is the main benefit of vacuum insulating glass compared to normal glass?
Vacuum insulating glass (VIG) offers significantly higher thermal insulation (U-value as low as 0.48) and superior noise reduction in a much thinner and lighter profile compared to traditional double or triple glazing.
Q2: Is LandVac glass safe for high-rise buildings?
Yes, it is a fully tempered vacuum insulated glass. It perfectly retains the safety features of tempered glass with surface stress exceeding 90MPa, meeting international safety standards for impact.
Q3: Does vacuum glass prevent window condensation?
Absolutely. The high vacuum interspace eliminates heat transfer, ensuring the interior glass surface remains free of condensation even when outdoor temperatures fall to -40 °C.
Q4: How long is the life expectancy of vacuum glass?
The life expectancy of our vacuum insulated glass exceeds 25 years, thanks to flexible edge sealing technology and built-in high-efficiency getter materials that prevent sealing failure.
Q5: Can it be used in refrigerators or wine cabinets?
Yes, its thin profile, energy-saving properties, and condensation-free performance make it ideal for freezers, wine cabinets, and commercial display cases.
Q6: What are the maximum dimensions available?
The maximum dimension for LandVac vacuum glass is 1500 x 2500 mm, with a minimum size of 300 x 300 mm.
