Advanced Vacuum Glazing Technology
LandVac is a high-performance vacuum glazing solution developed by LandGlass, offering a superior alternative to traditional double glazing. This innovative product consists of two tempered glass panes separated by micro support pillars, sealed around the edges, and incorporating a vacuum chamber within the cavity. The vacuum layer significantly reduces heat transfer, delivering outstanding thermal efficiency.
Long-Lasting Performance & Durability
Unlike conventional glazing, LandVac’s vacuum chamber prevents moisture and gas infiltration, ensuring stable insulation performance over time. The use of tempered glass enhances strength and safety, making LandVac ideal for both residential and commercial applications. This cutting-edge technology provides superior energy efficiency, acoustic insulation, and environmental benefits.
