What is Vacuum Glazing?

Vacuum glazing is a type of energy-efficient glazing that consists of two glass panes separated by a vacuum. This technology significantly reduces heat transfer across the window, providing better insulation compared to traditional double glazing. The vacuum between the panes minimises heat conduction and convection, making vacuum glazing a popular choice for buildings where energy efficiency is a priority.

Sash Window Preservation uses quality vacuum glazing, composed of Landvac and Fineo glass, ensuring a tight and secure seal on your windows. Our team works hard to ensure that your vacuum glazing is installed with care, so that your sash windows withstand the test of time.
