LandVac Optimum 25.1mm Unit Brochure
Vacuum Glazing is highly efficient double glazing. Like standard double glazing, it is made with
two panes of glass separated by a cavity. However, instead of the usual gas or air-filled cavity, all
air is extracted, and the unit is completely sealed.
The effectieness of the vacuum means that the gap between the two panes can be incredibly narrow – around 0.3mm. This narrow gap makes Vacuum Glazing the perfect choice for heritage
windows which emulate single glazing. When incorporated into triple glazing, like LandVac Optimum, performance is increased without requiring changes to window profiles.
