uPVC FOLDING DOOR TECHNICAL DETAILS

ULTRA SLIM SIGHTLINES

Timberlook uPVC Bi folding doors are manufactured from 60mm wide profiles creating exceptionally slim sightlines for a uPVC folding door which historically have been manufactured using much wider and heavier traditional door profiles.

Ultra Slim Sightlines The sight line size glass to glass is just 132mm for adjacent panels moving in the same direction which is considerably less than other upvc folding doors. Where the traffic door opens in the opposite direction to the main stack the sight line is 222mm. Where two traffic doors meet the sight line is 160mm and where two sliding doors meet the sight line is 256mm.

ALUMINIUM HEAD & THRESHOLD TRACK

A colour matched thermally broken aluminium frame head and threshold provides a concealed track for smooth and secure operation of the folding door system ensuring the doors cannot be lifted from the track whilst in the closed position.

THERMALLY EFFICIENT REINFORCING

Efficient Thermal Reinforcing Timberlook pvc-u folding sliding doors feature the latest innovative RCM(Recycled Composite Material) reinforcing which not only makes our upvc bifold doors more thermally efficient but because the RCM is welded at the corners at the same time as the sash profile it actually produces a weld strength 50% greater than a standard upvc frame.

RCM reinforcing is also lighter than traditional steel reinforcing so the individual panels are much easier to operate.

HARDWARE

Timberlook pvcu folding doors are manufactured using the same running gear, tracks, hinges and locking systems used on our popular range of timber folding doors.

Concealed Track and Hinges

Concealed Hinges The maintenance free rollers run in a concealed aluminium track system and the high security hinges feature fixings that are only accessible when the door is open ensuring there is no opportunity for a possible intruder to lift the door from the track or to force the hinges from the door to gain access. Concealed Track

Flush Track Option

Flush Track Option The aluminium track can be sunk into the floor to provide a flush threshold where the inside and outside floor levels are at the same height but other threshold options are available.

This image shows the flush threshold with an external projecting cill.

High Security Locking

High Security Locks Our Timberlook upvc bifold doors feature lever handle operated multi-point high security locking systems fitted with hardened steel hook bolts and dead bolt to traffic doors.

Shoot Bolt Locks Intermediate panels are fitted with internally operated shoot bolt locking into the frame top and bottom. Fold flat handles are fitted on these panels to minimise the stacking space when the door is fully open

Trickle Vents

Most doors require tricklevents to be fitted to comply with building regulations and these will be fitted to a 50mm high frame extender on top of the frame head.
