Solid Ash Window Boards & Internal Window Sills
Discover our premium range of Solid Ash Window Boards, expertly machined from carefully selected kiln-dried European Ash. Combining exceptional strength, attractive natural grain and outstanding durability, Ash is one of the UK's most popular hardwoods for high-quality interior joinery.
Whether you're renovating a period property, completing a modern extension or replacing existing window boards, our solid Ash window sills provide a beautiful finishing touch that combines natural character with long-lasting performance. Every board is machined to order and supplied unfinished, allowing you to apply the finish that best suits your home.
Why Choose Solid Ash Window Boards?
European Ash is highly regarded for its light natural colouring, distinctive flowing grain and excellent machining qualities. Its bright appearance helps create a clean, contemporary feel while retaining the warmth and individuality that only genuine hardwood can offer.
Unlike MDF or veneered alternatives, solid Ash window boards can be sanded, refinished and restored throughout their lifetime. This makes them an excellent long-term investment for homeowners, joiners and developers looking for both durability and timeless style.
Ash also offers excellent dimensional stability when correctly kiln dried and finished, making it suitable for a wide range of internal applications including living rooms, bedrooms, kitchens, dining rooms, home offices and commercial interiors.
Available Profiles
Our Ash window boards are available in a selection of carefully machined edge profiles to suit both traditional and contemporary interiors.
- Bullnose – A traditional rounded front edge offering a timeless appearance.
- Square Edge – A crisp contemporary profile with clean architectural lines.
- Chamfered Edge – A modern angled edge that provides a subtle decorative finish.
- Pencil Round – A softly rounded edge combining contemporary styling with everyday practicality.
Each profile is manufactured with the same attention to detail and precision machining, allowing you to choose the style that best complements your existing joinery and interior design.
Manufactured from Premium European Ash
Every Ash window board is produced from carefully selected kiln-dried European Ash. Kiln drying helps reduce the timber's moisture content before machining, improving stability and helping to minimise movement once installed.
Please note that boards measuring 200mm wide and above are manufactured using carefully selected jointed sections of solid Ash to achieve the required width whilst maintaining the strength, stability and appearance expected from premium hardwood.
As Ash is a natural material, every board will display its own individual grain pattern, colour variation and natural character. These variations are part of the beauty of genuine timber and ensure every installation is unique.
Perfect for Natural or Painted Finishes
Ash is an extremely versatile hardwood that can be finished in a variety of ways. Many customers choose clear hardwax oils or lacquers to enhance the timber's beautiful grain and pale natural colour, while others prefer stains or painted finishes to match existing skirting boards, architraves or interior décor.
Our window boards are supplied unfinished, giving you complete freedom to create the finish that best suits your project.

Solid Ash window boards are suitable for a wide range of residential and commercial applications, including:
- Replacement internal window sills
- New-build homes
