The most popular vision panel styles are shown below, although other designs can be accommodated. All aperture dimensions shown are cut-out sizes. A selection of glazing systems is available to suit styles as shown. Please refer to the Leaderflush Shapland Extended Performance Range for vision panels suitable for FD90 and FD120.

Vision panels

One of the key features of the Designer Range is the ability to integrate unusual vision panels. Whilst typical configurations are illustrated below, specifiers can also have the freedom to design doors that are individual.

Typical configurations

Within the Designer Range there are 11 commonly used vision panel configurations as illustrated above. As glazing has a major impact on fire performance, all configurations shown above provide up to 60 minute fire resistance.

The glass retention systems available include hardwood bolection and flush beads, or alternatively steel trims, all as detailed. For specialised glazing systems, for example with glazing and facing flush in appearance used in hygienic or similar areas, refer to the Plasform Range.

To ensure quality and specified performance, all doors must be factory glazed. Hardwood beads can either be fully polished or painted to match the door or doorset. These are generally fixed with steel pins, punched in and filled, although other fixing methods are available. Steel trim alternatives allow the designer to match vision panels with door furniture, protective plates or other accessories and are screw fixed into position. Glazing for vision panels in fire rated doors can either be wired or unwired, insulated or uninsulated and clear or obscured glass.

Non-typical configurations

For other shapes, sizes, positions and details of vision panels, the constraints set out in the ‘Specifying with Doors and Doorsets’ technical guide should be considered or discussions held with us at an early design stage.

Intelliglass®

Intelliglass® obscurable vision panels provide the ideal solution where privacy may be required, for example in environments such as hospitals, consulting rooms, banks, therapy rooms, commercial offices and schools.

Intelliglass® vision panels utilise liquid crystals which are sandwiched between two layers of transparent conductive film to make LC Privacy Film. The film is then laminated between two pieces of glass. When electricity is applied to the film the liquid crystals line up and the vision panel is clear. When the power is turned off, the liquid crystals return to their normal positions and turn the glass from clear to obscured.

The panels can be changed from clear to frosted at the flick of a switch. This intelligent glazing system can be automatically or remotely controlled by connection to a PC or by wireless connection or simply a switch adjacent to the doorset. As there are no protrusions to cause dust or dirt build-up, they are ideal for locations where hygiene is of prime importance.

The high-tech Intelliglass® vision panel solution obviates the need for cumbersome mechanical systems, blinds, shutters or curtains.

Intelliglass® is available in two standard sizes: 400mm x 400mm and 800mm x 250mm. For non-standard sizes please contact our Technical Services Department on: 01773 530500 or email: enquiries@leaderflushshapland.co.uk

Louvres and grilles

For ventilation, air transfer grilles or louvres can be fitted into Designer Range doors and doorsets.
