Over sills are used to extend existing window sills when installing EWI Systems. They are designed to prevent water ingress behind the system, ensuring you have a watertight seal to the top. The over sill is attached to an existing window sill extending the length to ensure it now overhangs the insulation. This over sill is 110mm in length, therefore is suitable for any insulation thickness between 50 – 80mm.
