Bi-fold Door System

Solid Engineered Hardwood Timber (Oak or Eucalyptus) Bi-Fold Door - Traditional character and natural warmth - enhanced!

10 Year Manufacturers Warranty

10 Product Warranty


Delivers a traditional, authentic natural look - ideal replacement for listed buildings or conservation areas.

Our solid Engineered Hardwood Timber Bi-fold doors, available in Oak or Eucalyptus and custom finished, blend perfectly with period architecture, heritage areas and bespoke builds. Typically chosen to enhance traditional buildings, or as an internal room divider, hardwood timber provides a real warmth and character.

Our EW68 solid engineered hardwood timber bi-fold doors are custom made and expertly crafted using our own (certified timber) profiles and manufactured to your exact requirements in our UK factory, meaning you are buying direct from the manufacturer!

Engineered hardwood timber profiles offer improved strength, stability and sound insulation, as well as eliminating timber swelling, shrinking or warping with changes in humidity.

All our timber products are dipped into an anti-rot, and anti-fungal treatment to protect the frames from both the harsh rays of the sun and water ingress. They are then finished to your specification using either a natural stain or a RAL color of your choice, or if preferred we can provide the doors unfinished so you can paint or stain to your desired finish.

A matching range of windows and doors are available.
