What Affects the Price?
- Number of panels — more panels = wider opening = higher cost. Each panel adds roughly £1,600.
- Timber species — Accoya is 15–25% more than hardwood.
- Glazing — triple glazing adds 25–40% to the glass cost. Passive glass adds 15–20%.
- Colour — white is standard. RAL colours add 5–10%. Farrow & Ball or dual colour adds more.
- Threshold — standard hardwood included. Aluminium low-profile or flush threshold adds £100–£200.
- Hardware — standard included. Upgraded handles add £50–£150.
Why Timber Costs More Than Aluminium
Aluminium bifold doors dominate the mass market because they're manufactured at scale in factories designed for volume production. The material is cheap, the process is standardised, and the product is good enough for most applications.
Timber bifold doors are built to order. Every set is manufactured to exact dimensions from engineered hardwood or Accoya. The joinery is more complex, the finishing is more labour-intensive, and the lead time is longer. You're paying for craftsmanship, not a commodity product.
The trade-off: timber is warmer (1,500× less thermally conductive than aluminium), repairable, refinishable, and better suited to period properties and conservation areas. Aluminium is slimmer, lighter, and maintenance-free but cold to the touch and impossible to repair if damaged.
Is Timber Worth the Premium?
Yes, if you value thermal performance, repairability, sustainability, or live in a conservation area where aluminium may not be accepted.
No, if budget is the primary concern and you want the slimmest possible sightlines.
