Wooden Window Frame Kits

Our wooden window frame kits are designed for use in sheds, workshops, garages and non-dwelling outbuildings across the UK. Manufactured in-house by Nottage Timber Merchants, each kit is made to measure, supplied flat packed and delivered unglazed and unfinished, ready for treatment and glazing on site. Whether you are fitting a new window into a garden building or replacing a damaged frame in a workshop or garage, our timber window frame kits offer a straightforward, practical solution.

Timber Window Frame Kits for Sheds, Workshops and Garages

What Is Included in a Wooden Window Frame Kit?

Each kit consists of the four timber frame components required to form a complete fixed window opening: two vertical stiles, a top rail and a bottom rail. The frame is supplied flat packed for ease of transport and handling, allowing it to be assembled on site using basic woodworking tools. All components are manufactured from softwood in our Pyle yard, machined to a consistent profile and accurate dimensions. The frame is supplied unglazed and unfinished, giving you flexibility over glazing method, preservative and paint finish. This makes our window frame kits particularly well suited to outbuildings where you want control over the final appearance and treatment.

Made to Measure Shed Window Frame Kits

Unlike off-the-shelf products designed around standard sizes, our shed window frame kits are made to measure to match your opening. Before ordering, you will need the finished opening dimensions, and we will manufacture the kit to suit. This approach works well for both new builds and replacement projects, where existing openings rarely align with catalogue sizes. Our timber window frame kits are suitable for sheds, workshops, garages, site offices, agricultural buildings and similar non-dwelling structures. If you are unsure about the right dimensions to specify or have an unusual opening shape, contact us before ordering and our team will advise.
