What Is A Window Sill?

The external window sill forms a protruding lip that directs water away from the brickwork.

Window sills are available in 3 sizes - 85mm, 150mm (standard) and 180mm. The 30mm height of the sill is included in your overall window height.

Ensure that you have clearance from the brickwork.

You do not have to have an external sill. For example you may have a stone sill and do not want an additional PVC-U one.
