Slate Cills
P.O.A
Our riven top Brazilian slate cills provide a refined and natural finishing detail for both internal and external applications, combining timeless style with outstanding durability. Carefully crafted from premium Brazilian slate, these cills showcase the stone’s distinctive riven surface, highlighting its natural texture and subtle colour variations. This organic finish makes them an excellent choice for projects that require an authentic, high-quality stone feature that enhances both traditional and contemporary designs.
All Brazilian slate cills are made to order, allowing them to be tailored precisely to your project requirements. The standard thickness is 25mm, however we can supply alternative thicknesses to suit different applications, including 10mm, 20mm, 30mm, and 40mm. This flexibility makes our slate cills suitable for a wide range of uses, from modern window detailing to more substantial architectural features.
Each slate cill can be produced in custom lengths and widths, ensuring a perfect fit for your window openings or design specifications. To further personalise the finish, we offer a variety of edge profiles, including bullnose, pencil edge, half bullnose, and chamfered edges. These detailing options allow you to achieve either a soft, traditional appearance or a clean, contemporary look, depending on your design vision.
In addition to the natural riven surface, polished or honed finishes are also available for projects that require a smoother, more refined aesthetic. Brazilian slate is renowned for its strength, low porosity, and resistance to moisture, making it a practical and long-lasting choice for window cills. Its durability ensures excellent performance in both interior and exterior environments, even in exposed conditions.
Our Brazilian slate cills are ideal for new builds, renovations, and heritage projects where quality and appearance are equally important. The deep, elegant tones of Brazilian slate complement a wide range of materials, including stone, brick, timber, and render.
With efficient production times, most orders are typically delivered within 10 working days, helping to keep your project on schedule. If you require advice on sizing, thickness, or finishes, our knowledgeable team is always available to help. Choose our riven top Brazilian slate cills for a bespoke, durable, and visually striking solution that adds lasting value and sophistication to any building project.
