Window Board TestimonialAvon Timber in Coventry have a range of MDF window boards in stock ready for collection or immediate delivery, and a wide range of solid wood window boards which are machined to order via our own Joinery workshop.

Solid Wood Window sill boards


With our newly fitted joinery workshop, we can machine any sized windowboard, either with squared and/or rounded edges, and out of any timber species available in the UK market. The images below are of our standard set of timber species i.e Oak, Pine, Ash, Beech, Maple, Sapele, Tulipwood and Walnut. We have chosen these species of timber as our standard available specimens soley because they are the most popular species of timber that we have machined products out of. Our standard set of windowboards are all finished to a 26mm thickness, start from a width of 195mm up to 595mm (please note that after a certain width, we have to biscuit join sections to achieve a wider windowboard whilst retaining stability), are rounded on the front long edge and at the ends, and are available with a lead time of approcimately 10 working days. We would like to emphasize that if you require anything else that isn't listed here as a standard product, to please provide us with the details either by calling us on 02476 304848, or by emailing us at, we would appreciate the opportunity of machining your windowboards for you.
