Midleton Precast Concrete recommend you refer to Eurocode 6 for masonry structure design guidance.


Precast concrete and reconstituted stone window sills (or to use the alternative spelling, “cills”), form the lowest horizontal part of window openings and perform both structural and aesthetic functions.

Window sills provide the structural seating for window frames which prevents water ingress, and are sloped outward to direct rainwater water away from the window frame. Window sills come complete with water drip channels on their undersides, to prevent mortar erosion and staining of the outer leaf material.

Midleton Precast Concrete offers one of the widest ranges of window sills you'll find, with profiles to suit brickwork, rendered block work, natural stone and stone cladding, as well as for both timber frame structural frames and traditional masonry construction.
Midleton Precast Concrete can deliver quickly, direct to site anywhere throughout Ireland, usually within 48 hours on standard units.

  • We have built up a product range with a wide range of window sill profiles.
  • We offer quick delivery on standard items.
  • We offer a non-stooled window sill specifically for timber frame construction.

– Specification for Precast Concrete Window Sills, Cast Stone, Clayware, Slate and Natural Stone



Midleton Precast Window SillsThe most important piece of information to know when specifying window sills is the placement of the window frame relative to the outer leaf material. This, together with the desired overhang relative to the outer face, determines the width of the sill you require. The other critical dimension is the face depth of the sill required to achieve your desired aesthetic.

Stooled window sills are normally used to complement exposed brickwork on the outer leaf, whereas non-stooled sills are usually the preferred choice for every other outer leaf material.

When specifying the length of the window sill, we normally allow for at least 75mm seating on each side of the opening, so use (Opening Width + 150mm) as a rule of thumb.

Many of our window sill profiles are compatible with our precast concrete and cast stone string course profiles. Please ask our experienced and helpful technical professionals for specification guidance.
