We are Sashed, trusted experts in beautifully crafted design led joinery.
We design, manufacture, and install unique and exclusive premium timber windows and doors for homes and properties across across England. From heritage homes in conservation areas to modern architectural designs, our bespoke, stunning and sustainable solutions combine timeless elegance with modernity and cutting-edge functionality.
We specialise in architectural windows and doors with ultra low‑profile designs rarely achievable in timber. We thrive on complex, highly bespoke projects.
Our specialist architectural timber products include:
Low profile lift and slide doors.
Our Low Profile Sliding Door system is more than just a door; it’s a statement piece that enhances the aesthetic appeal of any space. With ultra-slim 60mm jambs, frame head, stiles, and rails, this system delivers a sleek, modern look without compromising performance.
Our Pivot door systems can support much more weight compared to doors with traditional butt hinges; this allows the creation of huge door sets using a single-panel door, giving you a grand entrance aesthetic. For example, we can support up to 500kg in a single door, and depending on the type of timber and glazing used, we can create door sizes up to 3340mm wide in a single door panel. Our flexible pivot door profile also allows for sidelights and top lights within the construction of a single frame.
Our ultra-slim heritage sash box is perfect for buildings with narrow walls. Featuring vacuum glazing and a shallow 134 mm back-to-front frame depth, it replicates the look of a period single‑glazed window without protruding into the room.
Fire proof windows and glazed doors.
Our fire rated windows and doors are designed to resist the spread of fire for 30 minutes using specialist glass. This advanced fire-rated glazing system can even be specified in double-glazed configurations, offering fire protection while also maintaining thermal efficiency. Technically classified as fire rated screens, our fire rated windows are non-opening for maximum fire integrity. We can make them look indistinguishable period-style windows, we have even developed fire rated sliding sash-style windows that have been approved for planning in sensitive conservation areas.
Our fire-escape sash windows are engineered to open wider by incorporating a side-hung sash within an outer frame, ensuring safe escape routes in emergencies. They preserve the classic sash appearance while providing a reliable solution that meets fire-safety standards. From the outside they look like a conventional sash window but can open sideways to allow easy egress.
Along side our specialist products, we also have our compressive traditional product ranges, which can all be crafted to a projects specific requirement:
Our ‘modern’ range has exceptionally low u-values and is PAS 24:2022 tested and certified.
Our ‘heritage’ range has slim 56mm stiles and rails - ideal for heritage buildings where you need to closely match period joinery.
Our classic sash window is ideal for both period and contemporary buildings, and it is also suitable for new builds. Our PAS 24:2022‑tested sash features a slim 150 mm frame depth, giving it the authentic appearance of a period window while meeting modern security standards, including Part Q of the building regulations.
Single, French (double), and Stable doors
There’s a reason we originally ranked No. 1 on Google for “front doors London.” Our doors are extremely popular with discerning London clients. We engineer our timber door-sets with embedded steel elements in the stiles and rails, making them exceptionally stable and robust - eliminating common problems like misalignment, warping, and sticking.
Sashed timber bi-fold doors blend craftsmanship with innovation, bringing the outdoors into your home while delivering timeless beauty and high performance. We use Centor top-running bi-folding hardware, ideal for large and oversized frames—ensuring smooth operation, durability, and a slim, unobtrusive profile.
