Glazing has a major impact on fire performance and limitations are identified in the Building Regulations. Aperture shape and position, glazed area, style of bead and type of glass all influence fire performance, as well as appearance. The most commonly used aperture configurations, all available with fire certification up to 60 minutes, are shown in vision panel styles.

Those designated comply with Part M and with BS 8300 for disabled access requirements. Alternative designs can be accommodated and these should be discussed with us at an early stage. Three types of glazing bead are offered as standard – Timber Bolection, Timber Flush and Steel Trim - and these are used with various alternative details to suit specific fire ratings, aperture shapes and sizes.

Hardwood beads can either be fully polished, primed or painted to match the door. These are generally fixed with steel pins, punched in and filled, although other methods (such as screw fixings) are available. Steel trims can be powder coated, coloured to match door furniture, plates or other accessories and are screw fixed.

In some situations, safety glass will be required. All aperture dimensions shown in this section relate to the cut-out sizes. Details of special flush glazing systems, particularly suited to hygienic and 'high tech' applications, can be found in the Plasform Range section.

To ensure achievement of consistent quality, specified performance levels and fire certification, we strongly recommend that only factory installed glazing be used. We can supply doors with provision for on-site glazing but cannot certify work carried out by others and in such cases certification must be established separately. Apertures should not be cut into our products on site - as this will invalidate our certification.
