Vacuum Insulation Glass

Nov 30, 2017

In modern well insulated buildings U-values for walls of 0.3 W/(m2 K) or even below can be realized. In such buildings, glazings with typical U-values of 1.0 W/(m2 K) or higher are thermal weak spots in the façade. One attractive possibility to essentially improve the insulation properties of a glazing is to evacuate the space between the glass panes. This virtually eliminates heat transport due to conduction and convection of the filling gas. The glass panes can be prevented from collapsing by using a matrix of spacers (see Figure 1). Evacuated glazings are already available as a commercial product , however have U-values of 1.1 W/(m2 K) or higher.


Our revolutionary vacuum glazing technology provides unrivaled thermal performance in an ultra-thin unit that fits seamlessly into traditional andconservation properties. With this innovative unit you can retain the aesthetics by using the original frames. It provides the most advanced new solution for an age-old problem.

Our vacuum insulation glass consists of an outer pane of low-emissivity glass and an inner pane of clear float, with a vacuum rather than air or another gas in between. The result is excellent thermal performance from a unit only fractionally as thick as a standard one.
