Timber Sliding Doors

Bespoke Timber Sliding Doors

Sliding doors offer the widest unobstructed views of any door type. The panels glide horizontally on precision tracks — no swing space required, no folding mechanism to maintain. At Prime Sash Windows, we manufacture bespoke timber sliding doors in 2, 3, and 4 panel configurations, built to your exact opening dimensions.

Our timber sliding doors combine slim sightlines with generous glass areas. The result is a door that frames your garden like a picture window, while providing easy access and excellent thermal performance.

Sliding vs Bifold Doors

Bifold doors fold open to create a full-width opening — ideal when you want to merge indoor and outdoor space completely. Sliding doors keep their panels in the frame at all times, giving you cleaner sightlines and a more architectural look. They also require less wall space because panels stack behind each other rather than folding to one side.

For wide openings where maximum glass and minimal frame are the priority, sliding doors are hard to beat. For full open-plan access to a garden, bifolds win.

Frequently Asked Questions

How much do timber sliding doors cost?

Guide prices start at about £4,990 for 2 panels 2.4 m wide and £7,480 for 3 panels at 3.6 m (supply only, excluding VAT and installation; standard specification from our online configurator, October 2026), priced at £990 per square metre, or £1,260 per square metre for extra-wide panels with glass over 1600 mm.

How many panels can sliding doors have?

Two, three or four panels; the configurator shows which panels slide and in which direction.

Sliding or bifold doors?

Sliding doors give the largest panes and need no swing or stacking space but open to about half the width; bifolds open almost fully. Our patio doors comparison sets the two side by side with prices.
