Suitable for a variety of uses, the natural slate window cill provides a beautiful colour and has a sleek sheen to it. Ideally suited to external window and door cills to withstand the weather but can also be used internally, for slate wall capping, step and more. The slate originates from Brazil and is available in a range of sizes at a thickness or 30mm. We can machine to size for you, add a pencil round and add a drip bar if required – please enquire within on 01837 83573. All machining is charge extra to the cost of the cill itself. All cills are delivered as natural slate, no treatment has been added. We stock the Lithofin range of products should you wish to finish the slate with an oil, polish or stainstop. Lithofin products are sold separately.
