Timber Bi-fold Doors

— Open Your Home to the Outdoors
Folding walls of glass and warm natural timber — connecting kitchen, living space and garden in one smooth movement.
Bi-fold doors turn an entire wall into an opening. Ours are handcrafted from engineered FSC®-certified timber with precision-engineered folding hardware, so even wide multi-panel sets glide effortlessly and stack neatly to one side. With sets up to 12 metres wide, low threshold options and slim sightlines, they suit contemporary extensions and traditional homes alike.

Case studies

Edwardian Style Windows & Doors
— Cambridge

Replacing heavily worn sash joinery called for a delicate balance between rigorous aesthetic demands and the need for modern insulation. The solution lay in installing bespoke, top-tier timber Q4Sash windows and doors that replicate traditional profiles down to the finest detail while seamlessly integrating advanced glazing and concealed mechanisms. In effect, residents now benefit from superior thermal and acoustic comfort, whilst the refined appearance of the new joinery has reinvigorated the property’s period charm and boosted its overall market value.

FAQ

Yes. We have been manufacturing for the British market since 2011 and our transports run to the UK every week. Delivery to London and the surrounding areas is included as standard for other regions delivery is quoted individually. Every order is packed to furniture-grade standard before despatch.
We apply Remmers microporous paints and stains in multiple factory-controlled layers. Full RAL and NCS palettes, Farrow & Ball colours and custom shades are available, as well as translucent stains that show the natural grain.
Our windows, French doors and bi-fold doors are tested and certified to PAS 24:2016, the British security standard recognised by insurers, and use multi-point locking from leading hardware manufacturers.

We provide a 5-year guarantee covering the joinery construction, factory-applied coatings, glazing units and hardware (coatings without a UV filter carry a 2-year guarantee). Full guarantee terms are available on request.

Our bi-fold sets reach up to 12 metres in width, with up to 12 panels — each panel up to 1000 mm wide and 75 kg. Configurations range from two panels folding to one side up to six panels folding left and six folding right, inwards or outwards, stacking neatly to the side of the opening.
Both are available. A top-hung system keeps the bottom track minimal for the cleanest threshold; a bottom-rolling system carries the weight on the lower track, which can be preferable for very large sets. Our consultants will advise based on your structure and opening.
Not ours. Engineered timber is a natural insulator, and combined with double or triple glazing (from 0.8 W/(m²·K)) and QLON perimeter sealing, our bi-folds achieve whole-door performance of 1.4 W/(m²·K) — keeping the space comfortable year-round.
Yes. Our bi-fold doors are tested and certified to PAS 24:2016, the British security standard recognised by insurers, with multi-point locking and internally glazed panels.
