Cast Stone Window mullions are structural elements that vertically divide two or more adjacent windows. These stone mullians span from the window cill to the head, giving support to the head, lintel and the window frame, so they are critical load-bearing features. Stone Mullions have been used in buildings for many centuries, with their first appearance in European architectural being in the 12th century. As a key architectural element, Stone window & mullions are still popular today and can be seen in many contemporary buildings and period properties.Get a Quote
Our range of cast stone window mullions are compatible with many different window types, such as timber, aluminium and UPVC. We offer both traditional and more contemporary cast stone mullion designs, and all are available in a wide choice of stone colours. Our standard range of cast stone window mullions is suitable for many new build and self-build projects. In contrast, renovation projects typically require bespoke cast stone mullions to match existing features or fit non-standard window sizes.
For many new build or renovation projects, it is possible to produce bespoke cast stone window mullions matched to a specific design, including carefully reproducing existing original sections for historic buildings. We can easily do this at Procter, thanks to a mix of hand crafted mould creation coupled with the latest CNC technology. Our expert team will produce a cast stone result that will closely resemble natural stone mullions.
