The Practical advantages of Welsh Slate Window Sills

Slate is generally a non-porous material, which is exceptionally uniform and inert.  These properties make it extremely resistant to weathering and chemical attack, whilst the negligible water absorption of less than 0.3% protects it from frost damage. It is exceptionally durable, unaffected by normal extremes of temperature and it retains its colour, even in UV light. In addition, it is non-combustible and compatible with all other building materials. Welsh Slate is easily maintained, making it an economical choice for all building purposes and is readily available in a variety of sizes, colours and textures.
