Bespoke Timber French Doors
French doors are a timeless choice — two leaves that swing open to connect your interior with a garden, balcony, or terrace. They suit every style of property, from Georgian townhouses to modern extensions. At Prime Sash Windows, we manufacture bespoke timber French doors as single doors or paired leaves, opening inward or outward, built to your exact dimensions.
Unlike mass-produced uPVC alternatives, our timber French doors are built from engineered Accoya or hardwood — dimensionally stable, rot-resistant, and guaranteed for decades. The result is a door with authentic proportions, narrow sightlines, and the warm character that only real timber provides.

French Doors for Period Properties
French doors have been a feature of British architecture since the 17th century. In Conservation Areas and Listed buildings, replacements must match the original style — narrow meeting stiles, period-correct moulding profiles, and authentic proportions. Our French doors replicate these details precisely while incorporating modern performance features: multi-point locking, draught seals, and thermally efficient glazing.
For period properties, we can add Georgian glazing bars — either planted (applied to the glass surface) or through-bars (integrated into the frame). Both options are available in our 3D configurator.
