Cast stone cills are precision-manufactured architectural components designed to replicate the appearance and texture of natural stone window cills. Made from high-quality aggregates, white cement, pigments, and specialist additives, cast stone cills provide an elegant and durable finishing detail beneath windows and openings in both traditional and modern buildings.

Cills serve a functional purpose by helping to direct rainwater away from the building facade, reducing the risk of water ingress and staining. Cast stone cills are engineered with appropriate drips and slopes to ensure effective water management while enhancing the overall architectural aesthetic.

In the brick cladding and construction industry, cast stone cills are commonly specified for:

• New-build residential and commercial developments

• Heritage restoration projects

• Period-style homes

• Contemporary designs requiring classical detailing

Available in a range of standard sizes, profiles, and bespoke designs, cast stone cills complement brickwork, stonework, render, and cladding systems seamlessly. They deliver the charm and visual appeal of quarried stone but with the benefits of modern manufacturing — including consistent quality, improved sustainability, and reduced costs.

Whether you’re restoring a classic archway or incorporating timeless design into a modern project, our cladding solutions offer the durability and aesthetic appeal needed to highlight these intricate features. With our easy-to-install brick slips and cladding options, you can achieve the look of expertly crafted masonry while benefiting from contemporary performance standards.
