What is Vacuum Glazing?

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 effectiveness 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.


The sleek Ultra-Thin profile makes this perfect for existing double glazing profiles.


The LandVac unit is always constructed from two panes of 4mm toughened glass.


This product has exceptional thermal efficiency, exceeding quad glazing, but in an ultra thin profile.


Industry leading 10-year warranties and an anticipated lifespan in excess of 25 years.


Leading acoustic performance, without the need for thicker, heavier panes of glass.


The bare LandVac units are fully recyclable and have no noble gasses which are energy intensive to produce.
