Riven Cleft Window Sills

Cleft window sills have a slightly textured surface very flat and consistent. Very popular with home builders for its price and quality we have standard sizes available to suit most windows openings.

We have a selection of sizes available in our cleft range with two widths to suit both rendered and cl-added wall construction. All standard cleft window sills will have a fine rubbed and beveled front long edge with an option to add a drip groove at an extra cost.
