We call “special shapes” all double glazing units that do not have a classic rectangular shape, i.e. curved, full-curved, trapezoidal or oval shapes.
Moder vacuum double glazing manufacturers can produce special shape double glazing, which is a key factor in the aesthetic and charm of period arch sash windows used.

We take precise measurements of the glazing of each sash window and order the glass. When double glazing is delivered, we work on the window frames in much the same way as we would for a rectangular window, except that we more often use special router accessories mounted on a router. This way, the glazed space, after the double-glazing has been fitted and wedged into its new rebate, is kept strictly identical!
As with all our windows, the result is a window whose wooden frames has been restored to their original state, while adding the modern performance of modern double glazing and placing insulating seals around all edges.
