We supply and install slim‑framed bi‑fold doors in aluminium and timber, offering flexible solutions to suit a wide variety of homes. Available in an extensive range of colours and configurations, bi‑fold doors can be tailored to suit different opening sizes, layouts and design preferences. Both materials are valued for their strength, thermal performance and weather resistance, ensuring long‑lasting reliability alongside striking aesthetics.
Bi‑fold doors are a popular choice for homeowners thanks to their unique concertina opening mechanism, which allows the door panels to neatly fold and stack to one side. Smooth‑running roller systems ensure effortless operation, helping to create a wide, unobstructed opening that seamlessly connects indoor living spaces with the garden for a bright, open‑plan feel.

Bi‑fold doors offer a contemporary style that can be tailored to suit a wide range of properties thanks to their flexible design options. Available in both aluminium and timber, bi‑fold doors can be finished in a carefully selected range of colours, along with realistic wood‑effect finishes where appropriate. Dual‑colour options are also available on selected systems, allowing you to achieve a distinctive look inside and out.
To complete the design, you can choose from an extensive selection of door furniture, including modern and traditional handle styles in a variety of finishes. This allows your new bi‑fold doors to complement your home’s architectural character, whether your preference is sleek and contemporary or more classic in appearance.
In addition to their visual appeal, bi‑fold doors are highly versatile in their configuration. They can be designed with a range of panel combinations, typically from two panels up to larger multi‑panel layouts, depending on the size of the opening and how you want the doors to function. Whether you’re looking for minimalist aluminium bi‑fold doors or a more traditional timber design, our made‑to‑measure solutions ensure a perfect fit for your home.
When choosing bi‑fold doors, security is just as important as style and performance. Our bi‑fold door systems are manufactured to high standards and designed to provide dependable protection for your home, without compromising on sleek appearance or smooth operation.
Both aluminium and timber bi‑fold doors incorporate advanced locking systems, including multi‑point locking as standard on suitable configurations. Glazed panels are manufactured using toughened or laminated safety glass, providing added resistance against impact and forced entry. When appropriately specified, bi‑fold doors can be supplied to meet recognised security standards such as PAS 24, offering additional reassurance.
By combining robust materials, modern locking technology and high‑quality glazing, bi‑fold doors provide a secure solution that allows you to enjoy open‑plan living with confidence, knowing your home remains well protected.

Slimline bi‑fold doors allow large amounts of natural light to enter the home thanks to their slender frame design, helping to create bright and open living spaces. While their appearance is contemporary, bi‑fold doors are also engineered with thermal performance in mind.
Manufactured with advanced sealing systems and robust door construction, bi‑fold doors are designed to reduce draughts and limit heat loss when closed. When specified with high‑performance double glazing, they help retain warmth inside the home, supporting a more stable internal temperature throughout the year.
By reducing unnecessary heat loss, energy‑efficient bi‑fold doors can help lower heating demand over time. This not only contributes to improved comfort but also supports reduced energy usage, making bi‑fold doors a practical option for homeowners looking to balance modern design with everyday efficiency.
The cost of bi‑fold doors varies depending on several factors, including the material, size of the opening, configuration, colour finish, glazing specification and choice of hardware. As bi‑fold doors are made to measure, pricing is tailored to each individual project. To obtain an accurate quotation, it’s best to speak with a bi‑fold door specialist who can assess your requirements and recommend a suitable solution.
External bi‑fold doors consist of two or more glazed panels that operate on a tracking system, allowing the panels to slide and fold neatly to one side. This creates a wide, unobstructed opening and makes bi‑fold doors an ideal option for connecting indoor living spaces with the garden, patio or terrace while maximising light and ventilation.
In most cases, planning permission is not required for exterior bi‑fold doors, as they are typically covered under permitted development. However, requirements can vary depending on factors such as the property type, location, and any restrictions that may apply to listed buildings or homes in conservation areas. It’s always advisable to check with your local authority or planning department to ensure compliance before proceeding.
