Sound insulating manually operated or semi-automatic moveable wall system providing the possibility of high level sound insulation requirements. It comprises individual top hung full height panels of equal size, made to measure to suit site dimensions. When the wall is closed between fixed abutments, it gives the appearance of a solid flush wall.

Variflex is ideal for any application where the purpose is to make people meet, communicate and generally feel comfortable in their surroundings. It has a wide choice of elements and stacking/ parking arrangement options and its high level of flexibility, even in the case of complicated room proportions where sloping ceilings or circular spaces have to be accommodated, ensures optimum functionality. As well as offering very effective smoke control, the latest European standards are met with up to Rw 60 dB sound reduction.

Complies with BS EN ISO 14025 for environmental labels and declarations and is acoustically tested to BS EN 140-3.

Standard product features


Tri-block panels are constructed of a non-deflecting steel tube frame complete with independent aluminium edge profiles. The frame is clad either side with 16 mm, three-ply quality chipboard panels hung in acoustic isolation from the frame and allowed to vibrate independently. The panel face boards are easily removable without the need to remove the whole panel offering an added benefit for health and safety with manual handling. The track is manufactured from extruded aluminium and the track junctions incorporate drop forged roller bearings. Carriers are fully adjustable and are secured to the panels by horizontal ball bearings which engage with shock absorbing roller pins.


Each element incorporates spring loaded top and bottom mechanical seals. Seals are operated by means of a removable ‘crank’ handle and engaged by a winding mechanism to ensure optimum contact pressure of 1500 N minimum. Seals are constructed of aluminium with flexible rubber inter locking contact points.

Concave and convex aluminium edge profiles with integrated quad-lip gasket.
