Timber doors for flexible living spaces

Timber bi-fold doors are a popular choice for opening up a living space, folding neatly to one side in the style of a handheld fan to create wide, clear openings. Often called concertina doors or fold doors, they’re unrivalled for natural light intake, access and flow.

Sliding doors, sometimes referred to as patio doors, are different but equally effective. As opposed to folding concertina-style, these large glass panels glide smoothly behind one another, stacking at the end. A great option where space is limited and simplicity is desired.

Why choose Kirkman bifold and sliding doors?

Handcrafted, sustainable timber doors made locally in Oxfordshire.

Handcrafted joinery

Every door set is made in-house using traditional joinery methods and Accoya® timber for strength, accuracy and an authentic finish that stands the test of time.

Sustainable timber choices

We use FSC-certified Accoya® timber, sourced responsibly through trusted suppliers like Latham Timber.

Low maintenance finishes

Advanced coatings and durable Accoya® timber mean very little maintenance compared with older wooden bi-folds or softwood doors.

Designed around your home

Sizes, layouts, colours, glazing and finishes are tailored to suit your living space, existing windows and buying priorities.

Excellent thermal efficiency

High performance glazing and tight tolerances help reduce heat loss and support lower energy bills, as well as a more comfortable living space year-round.

Long-term peace of mind

Backed by a 30 year preservative guarantee, 8 year coating guarantee and a 10 year guarantee on the complete product.

Timber bi-fold doors

Accoya® timber bi-fold doors fold back panel by panel, stacking neatly to one or both sides. They create wide openings and suit homes where indoor and outdoor living connect closely. Choose bifolds if you want flexibility and full access.

  • Slimmer sightlines for higher natural light intake
  • Excellent for external use with wide openings
  • A more traditional option than aluminium bi-folds

Timber sliding doors

Sliding doors glide smoothly on discreet tracks, requiring less floor space. They suit contemporary homes and patios where space may be more limited, and a simpler way of opening is desired.

  • Ideal where space is limited
  • Strong visual connection to the garden
  • A popular choice for modern homes

Bi-fold or sliding doors compared

Both door styles improve natural light, energy efficiency and the value of your home, but suit different spaces. Bi-folds prioritise external views and flexibility, while sliding doors focus on simplicity and space-saving.

  • Choose bi-folds for maximum opening width
  • Choose sliding doors if you have limited floor space
  • Both outperform many aluminium and uPVC door options thermally

Why timber works so well

Timber doors offer warmth, character and performance that uPVC and aluminium doors struggle to match. Unlike aluminium bi-folds, timber has natural insulating properties, helping to authentically reduce heat transfer and improve thermal efficiency without relying solely on a thermal break.

At Kirkman Joinery, our experience, in-house manufacturing process and small specialist team mean every door is built properly, independently tested, finished carefully and fitted to meet current building regulations.

The materials are top notch and the traditional design is perfect for our period house. I would have no hesitation using them again and the pricing is much more competitive than their bigger brand rivals.”
