Window Stool Moulding KD Finger-Jointed Pine 2.44m Primed White Sill Trim for Indoor Decoration

The GTR Window Stool Moulding is a kiln-dried, finger-jointed pine sill profile built for tidy indoor window installations. Every length is sanded between primer coats and delivered in a uniform primed white finish that accepts almost any topcoat without extra preparation. Because the timber is finger-jointed, the strip stays straight and stable across long spans, which reduces waste and rework on site. The profile is aimed at renovation contractors, joinery shops and building material distributors who need a dependable, ready-to-paint sill in volume.

A window stool sits directly below the sash and forms the ledge that finishes the indoor side of a window opening. Trim fitted beneath the stool adds shadow lines and a decorative touch that upgrades the whole frame. GTR produces this moulding from sustainably sourced softwood that has been dried to a controlled moisture range, so the section will not twist after installation. Consistent machining means each piece locks into the same reveal, batch after batch.

• Kiln-Dried Stability: Timber is dried to 10-13% moisture content, keeping the profile flat and resistant to warping in heated or humid rooms.
• Finger-Jointed Strength: Short clear offcuts are precision jointed into long, strong strips that behave like solid stock and cut cleanly.
• Primed White Surface: One coat of gesso plus two coats of water-based primer are sanded between layers for a smooth, sealed base.
• Ready For Any Topcoat: The sealed surface holds both water-based and oil-based paints, so finishing teams can match any interior scheme.
• Tight Tolerance: Dimension tolerance of plus or minus 0.3mm keeps mitres accurate and joints close during installation.
• Economical Solid Look: Delivers the appearance of solid timber at a lower cost per running metre than wide clear boards.

The stool moulding is specified for residential window interiors, hotel guest rooms, hospital wards and school buildings where a clean, painted sill finish is required. It also suits shopfitting and office fit-out work, and pairs naturally with matching window casings and aprons sold in the same range. Contractors value it because the profile covers the joint between the rough opening and the stool while hiding small gaps left by the plasterer.

Lengths are bundled, shrink-wrapped and stacked on export-grade plywood pallets for container loading. Each bundle carries a moisture-proof liner that protects the primed face during sea freight. Every production run is checked for moisture content, straightness, surface finish and priming coverage before dispatch, and a quality record travels with the shipment so buyers can trace the batch.

Custom lengths, widths and thickness are available from 14mm to 300mm wide, so architects can match an existing detail exactly. Tooling for new decorative profiles can be developed on request, and free samples are supplied for approval before mass production. Buyers may mix several profiles in one container to test the market, and our team will confirm tooling lead times and packing plans with the order acknowledgement.
