Yorkshire Stone Heads and Cills

Natural Stone Heads & Cills for Windows and Architectural Openings

PG Stone supplies natural Yorkshire stone window heads and cills for use in new build, renovation, and restoration projects across the UK.

Window heads and cills are critical architectural details — both structurally and aesthetically. Natural stone heads and cills are widely specified by planners on developments in conservation areas and National Parks, where sympathetic materials are a planning condition. They are also increasingly chosen by developers and architects on high-specification new builds where quality of finish is a differentiator.

We supply reclaimed Yorkshire stone heads and cills salvaged from original buildings, as well as new stone dressed to size, ensuring availability across a range of opening widths and projections. Our team can advise on standard and bespoke sizing based on your project’s requirements.

See examples of our heads, cills, jambs, and mullions below.

Heads and cills (sometimes spelled sill), are masonry stones used around a window or door to create a good solid opening. The cill goes to the base, the head is at the top, then there are jambs which are optional at the sides of windows and doors, and in addition, there are mullions that break up a window or door opening either vertically or horizontally (once again these are optional).

At PG Stone (Yorkshire) Ltd we offer a wide range of new heads, cills, jambs, and mullions which are cut to order in natural stone and are perfect for creating made-to-measure window and door apertures in character properties.

The overall look of a building is influenced by the styling of the heads, cills, jambs, and mullions, at PG Stone (Yorkshire) Ltd we can cut the above products to any size required and our masons can add details such as stools, chamfers, moldings or other carved decorations. In addition to the detailing, we can create different textures and shades through sandblasting and dyeing which can dramatically alter a property so that it stands out or blends in with the environment it’s built in.
