Timberlook Slim Sash PVCu Bi-Fold Doors

Most PVCu Bi-Folding Doors are made from bulky door profile & include unsightly face-fixed hinges.

Timberlook Slimline Bi-Fold Doors are different.

We combine high-strength PVCu & Aluminium profiles to achieve the sight lines of aluminium bi-folds with the
cost-effectiveness of PVCu.

Main Features

  • Replicate timber sections with an ovolo profile.
  • Have high-security hardened steel hook locks that prevent the hinge being forced from the door.

The Head & Thresher are aluminium and do not have a PVC-u frame and as such are more robust.

The Aluminium Head & Thresher encapsulate the running gear so that the door cannot be lifted from the track.


The Timberlook Bi-Fold aluminium thresher is 51mm high.


The Threshold can be fitted flush to the inside and outside floor and is also available with an external clip-on aluminium cill that does not increase the threshold height of 51mm.


The rollers are concealed and are resistant to attack from potential intruders.


Hardened steel hook locks, dead bolts and top/bottom shootbolts are specified for high security and flat handles minimize stacking space when opened.


The wheels, which are stainless steel, operate quietly and smoothly and have sealed bearings for maintenance free use.


There are 4 expansion seals between each door.
