Smooth, stable, and highly versatile, MDF (Medium Density Fibreboard) is a go-to engineered wood product for a wide range of interior building and design projects. We carry high-quality MDF panels and mouldings ideal for cabinetry, shelving, furniture, wall panelling, and detailed trim work. Made from finely ground wood fibres bonded under heat and pressure, MDF offers a uniform surface that’s perfect for painting, veneering, or laminating. It machines cleanly without splintering, holds edges well, and is ideal for precision cutting, making it especially popular for decorative mouldings and custom millwork. As a proudly Canadian company, Windsor Plywood provides trusted building materials and expert advice to help you complete projects with confidence. Whether you're crafting a built-in unit or upgrading interior details, MDF delivers reliable performance and a smooth, professional finish every time.
Casing is the trim moulding that frames the perimeter of a door or window opening, covering the gap between the frame and the wall finish. It is both functional and decorative, concealing the rough opening and adding a finished, polished transition between the door frame and the wall.
Windsor Plywood stocks casing in traditional ogee and colonial profiles, clean craftsman-style flat profiles, contemporary square-edge options, and various intermediate styles. Available in solid wood species including pine, oak, and hemlock, as well as paint-grade MDF and finger-jointed options.
Standard residential casing runs between 2.25 inches and 3.5 inches wide. The right width depends on the door size, ceiling height, and surrounding trim. Wider doors and taller ceilings support wider casing. For a balanced look, casing width should be visually proportionate to the baseboard height in the same space.
Consistency within a room creates a unified, intentional look. Using matching casing profiles on all doors and windows in a space is standard practice. You can introduce subtle variation between floors or between formal and informal spaces, but mixing profiles within the same room typically looks unfinished.
The terms are often used interchangeably in residential context, both referring to the trim framing a door or window. Architrave is the more formal architectural term, and in some contexts refers specifically to larger, more decorative door surround trim. In practice at Windsor Plywood, both refer to door and window frame moulding.
