Precast Concrete Window Sills in Kenya

PRECAST CONCRETE WINDOW SILLS
Precast Concrete Window Sills (or “cills” as they’re sometimes referred to) are used below windows and ledges. They are an important architectural feature to any building but also provide the seating for an airtight seal with the window frame, preventing water ingress. The outward slope of the sill directs rainwater away from the frame and a drip channel on the underside prevents staining and deterioration of the outer skin of the building.
