Window Sills
Cast stone sill profiles for windows, openings, veneer transitions, and coordinated façade surrounds.
Lines that define architecture
Precisely cast surround, band, and trim profiles that frame openings and organize façades.

This is M1’s catalogue-traced section, not a generic family shape. Its straight display length is illustrative. Drawing-derived projections are identified in the measurements. This is not fabrication CAD. Digital color and texture are approximate; approve a physical sample. See all four precast finishes and 19 colors.

Explore each moulding’s own traced profile in real 3D. Height and projection are shown in inches; M8, M21 and M23 have drawing-derived maximum projections, identified below. The straight run is illustrative—not a stock length. M51 and M72 are not present in the published catalogue.

Interactive catalogue
Explore all 97 published moulding sections as individual 3D profiles, alongside their official drawings. Check height, projection and reconstruction notes, then shortlist up to three for your project.
Architectural
Precast mouldings define openings, rooflines, and façades with repeatable, detailed profiles. This M-series collection focuses on surrounds, bands, and trim made before components arrive on site.
For a projecting sill with drainage slopes and drip details, use the separate Window Sills collection. Landmark Stone can coordinate both families in the same color and texture.

Applications
A starting point for design conversations. Project conditions, engineering, attachment, and local requirements should be reviewed for the final assembly.

From reference to release
A catalogue code is a useful starting point, not the whole specification. Send the available project information and the team can help close the gaps before fabrication.

Target color, texture, adjacent materials, and the light conditions used for sample approval.
Substrate, attachment assumptions, delivery sequence, site access, and required milestone dates.
Common planning questions
Mouldings and surrounds frame the sides and heads of openings. Projecting window sills form the lower element and require their own profile and interface review. Select the pieces together for a coordinated opening.
Yes. Catalogue families establish proportion and design direction. Final size, length, returns, radius conditions, color, texture, and project interfaces can be reviewed for the selected application.
Send the model or design reference, dimensioned drawings when available, quantities, project location, desired finish, and schedule. Early sketches are also welcome when details are still being developed.
Digital finish studies help narrow the direction, but physical samples should be reviewed beside adjacent materials and in the project’s actual light before final approval.
The final assembly depends on piece geometry, substrate, loading, access, and local requirements. These conditions should be coordinated with the project team before release.
