Bespoke External Bi-Fold Doors UK
Timber Bi-Fold Doors
Our timber bi-fold doors are designed to create wide, elegant openings while delivering the strength, precision and durability expected from premium British timber joinery. Particularly well suited to patios, garden rooms, contemporary extensions and high-end residential projects, they offer a refined alternative to French doors and sliding doors for homes across the UK and Ireland.
Engineered for large clear openings, our bespoke timber bi-fold doors fold multiple panels to one or both sides of the frame, creating a strong visual connection between the interior and the garden while using minimal stacking space. This makes them an ideal choice for homeowners and designers looking for external timber bi-fold doors that combine architectural impact with practical everyday use.
Each door set is built on CENTOR high-load hardware, ensuring precise panel alignment, smooth operation on stainless-steel bearings and long-term reliability even in larger multi-panel configurations. Robust timber profiles, carefully developed sealing details and adjustable hinges help maintain excellent air-tightness, water-tightness and resistance to wind loading.
Available in a wide range of opening arrangements, our external timber bi-fold doors can be configured with inward or outward stacking, multiple panel numbers and an optional traffic door for convenient daily access. The result is a high-performance folding door system that combines generous openings with the craftsmanship, stability and finish quality expected from premium timber doors in the British and Irish markets.
Construction of Timber Bi-Fold Doors
Our timber bi-fold doors are engineered with a 140 mm frame section and 58 mm sash profiles, providing the structural rigidity required for large glazed openings and multi-panel folding systems.
The deeper frame section helps ensure stable load transfer across the full installation, while the 58 mm sash thickness allows secure integration of modern glazing units and high-load CENTOR folding hardware. This construction supports reliable panel movement, accurate alignment and consistent weather performance across the entire bi-fold set.
All components are precision-machined to maintain tight tolerances, helping to ensure correct sash geometry, even gasket compression and dependable operation over repeated opening cycles. The system is designed to deliver the long-term durability and dimensional stability expected from premium timber bi-fold doors used in the UK and Ireland.
Opening Configurations for
External Timber Bi-Fold Doors
Our timber bi-fold doors are available in a full range of opening configurations, allowing panels to stack to one side or divide and fold to both sides, depending on the proportions and practical requirements of the project.
Depending on the width of the opening, the system can be designed with three, four, five or more panels. This flexibility makes it possible to create anything from a modest terrace opening to a wide, open connection between interior living spaces and the garden.
For everyday convenience, many configurations can incorporate a traffic door. This allows quick and practical access without opening the full bi-fold set, which is particularly useful for frequently used patio entrances and family living areas.
Panels fold and slide along a continuous track, creating large clear openings while requiring minimal stacking space internally and externally. This makes bespoke timber bi-fold doors a practical and elegant solution for both contemporary homes and more traditional properties requiring carefully detailed timber joinery.
Hardware for
Timber Bi-Fold Doors
Our timber bi-fold doors are built on the CENTOR high-load folding hardware system, selected for precise panel alignment, smooth running and long-term reliability in multi-panel door arrangements.
The system uses stainless-steel bearing carriages to ensure consistent movement and dependable performance over time. Fully adjustable hinges allow accurate installation and help maintain correct gasket compression, supporting air-tightness, water-tightness and overall weather resistance. The centre hinge can also be specified with an integrated pull handle, making it easier to control the folding leaves during operation.
Optional leaf-alignment magnets are available to stabilise intermediate panels when open, helping to prevent movement in windy conditions and keeping the folded leaves neatly stacked.
All visible hardware components, including hinges, carriers and handle sets, are available in polished chrome, satin chrome, bright brass and black, allowing the finish to be coordinated across the entire system. Traffic doors are fitted with FAB & FIX BALMORAL lever handles, while the folding leaves use key-locking dropbolts at the bottom for secure anchoring and improved anti-lift performance.
Glazing Options for
Timber Bi-Fold Doors
Our timber bi-fold doors are supplied as standard with 24 mm double-glazed units achieving Ug = 1.1 W/m²K, fitted with a warm edge spacer to reduce thermal bridging and help minimise perimeter condensation.
All standard glass in our bi-fold door systems is toughened in accordance with UK Building Regulations Part K, which requires safety glazing in low-level and door-height applications. This provides the level of protection expected for large glazed door sets used in everyday residential environments.
The glazing specification has been developed to support the performance of external timber bi-fold doors, combining strength, thermal efficiency and durability with the elegant appearance expected from premium exterior timber joinery.
Special Glazing for
Timber Bi-Fold Doors
For projects requiring enhanced performance or more specialist detailing, we offer a wide range of glazing options for our timber bi-fold doors.
Where enhanced security is required, laminated safety glazing can be specified to improve resistance to forced entry and provide additional integrity in the event of breakage. Laminated glass is particularly valuable in ground-floor installations and locations where greater security is needed.
For sun-exposed elevations, solar-control glazing helps reduce solar gain while maintaining high levels of natural daylight, supporting a more comfortable indoor environment in warmer months. For homes in busy or urban settings, acoustic glazing is available to improve sound insulation and reduce the transmission of external noise.
We also offer ornamental glass for privacy and traditional stained-glass units for projects requiring additional character, colour or architectural depth. These options are especially suited to period homes and design-led installations where glazing contributes to the overall visual language of the property.
Timber Options for
Bi-Fold Doors
Our timber bi-fold doors are manufactured from FSC-certified pine, larch, spruce, meranti and Accoya®, selected for strength, dimensional stability and long service life in large multi-panel door systems.
All timber is precision-engineered and moisture-controlled to ensure reliable performance, accurate hardware alignment and long-term resistance to movement or warping. This is especially important in external folding doors, where the scale of the opening and the weight of the panels place significant demands on the material.
Careful timber selection and controlled processing allow us to create bespoke timber bi-fold doors with the structural quality, stability and refined appearance expected from premium exterior joinery.
Finishes for
Timber Bi-Fold Doors
All of our timber bi-fold doors are finished with high-performance Remmers exterior coating systems, developed to withstand demanding British and Irish weather conditions.
Clients can choose from the full RAL palette as well as premium Farrow & Ball and Little Greene shades, allowing the doors to complement both traditional and contemporary architecture. For a more natural appearance, we also offer tinted stains and Natural Effect coatings that highlight the beauty of the timber grain while maintaining full exterior durability. Dual-colour finishing is also available.
Each bi-fold door set is treated using a multi-stage finishing process that includes deep impregnation, industrial priming and hydrodynamic spray application. This helps ensure long-lasting protection, colour stability and the premium surface finish expected from high-quality timber bi-fold doors.
Glazing Bar Options for
Timber Bi-Fold Doors
Our timber bi-fold doors can be specified with 20 mm or 24 mm astragal glazing bars, allowing the system to achieve a more traditional divided-light appearance while maintaining the thermal performance of the insulating glass unit.
For applications requiring deeper sightlines or additional rigidity across wider panels, structural glazing bars are also available. These provide increased support while preserving the visual coherence of the design.
Bi-fold systems can also be fitted with ornamental or patterned glazing units to provide privacy or to echo architectural detailing elsewhere in the property. For bespoke projects, we also manufacture custom glazing bar layouts, making it possible to replicate more complex traditional patterns within a folding door arrangement.
Optional Features
for Timber Bi-Fold Doors
Our timber bi-fold doors can be enhanced with a range of optional features designed to meet project-specific requirements for ventilation, appearance and performance.
Trickle vents are available with an integrated head drip or external plastic canopy, providing compliant background ventilation while helping to protect the frame from water ingress. For designs incorporating solid sections, we offer raised and fielded timber panels in 46 mm thickness, as well as flat panels in 24 mm, allowing the door set to reflect more traditional joinery styles or a cleaner contemporary aesthetic.
All optional elements are fully compatible with our bi-fold door system and are designed to maintain the structural, thermal and weather-performance standards expected from premium timber joinery in the UK and Ireland.
External Timber Bi-Fold Doors for
Contemporary and Traditional Homes
Our external timber bi-fold doors are designed to suit a wide range of architectural settings, from contemporary extensions and garden rooms to traditional houses requiring bespoke timber joinery of a more classic character.
Because the system combines large glazed openings with premium timber construction and refined finishing, it creates a strong visual connection between inside and outside while still sitting comfortably within the architecture of the building. The availability of different opening configurations, glazing bar arrangements, finishes and panel options allows each door set to be tailored to the character of the property.
This makes timber bi-fold doors an excellent choice for homeowners, architects and developers looking for premium external doors that combine design flexibility, long-term durability and architectural quality.
