THRESHOLD OPTIONS

Timberlook uPVC folding doors are available with a choice of three threshold options to suit your requirements.

FLUSH TRACK

Track Recess The aluminium track and threshold is 52mm high but 45mm can be buried in the floor creating a flush track system that is especially suitable for internal folding sliding doors installed between the house and conservatory where a continuous floor level is required.

FLUSH TRACK WITH PROJECTING CILL

Flush Track With Projecting Cill For external folding doors the track can be fitted flush to the inside floor level by lowering the external brickwork and an external aluminium projecting cill can be supplied.

RAISED TRACK WITH PROJECTING CILL

Raised Track With Projecting Cill Our uPVC Bifold doors can also be supplied with a conventional raised threshold and a projecting cill that does not increase the threshold height of 52mm. This is still a very low ‘step-over’ threshold when compared to other upvc folding doors.

RUNNING GEAR

The sliding folding door panels are fitted with stainless steel rollers to top and bottom of the panels for easy smooth operation. The rollers have sealed bearings for maintenance free use and because the running gear is encapsulated in the aluminium frame head and threshold the doors cannot be lifted from the track ensuring they are resistant to attack from intruders.
