home » glazing » Longden is able to supply many of the door styles detailed on panelled doors with glazed panels in place of solid panels. Where vision panels have been specified, glass type will be determined by performance characteristics required. The table below outlines the glass performance characteristics. When specifying external doorsets, double glazed units can be supplied.
Bevelled glass
As an alternative glazing option, Longden can supply bevelled glass. Bevelled glass is usually found on the inner face of the door leaf but if specified, Longden can supply bevelled glass on both the inner and the outer face of the door leaf.
Where more decorative glazing effects such as acid etching is required, Longden can advise on all options available. For more information regarding speciality glazing please refer to accessories.
