Glazing

Glazing has a major impact on fire performance and limitations are identified in the Approved Documents. 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 120 minutes, are shown below.

Alternative designs can be accommodated and these should be discussed with us at an early stage as shape size and position is subject to certification parameters.
All aperture dimensions shown in this section relate to cut out size if beaded or clearview dimensions if Flushglaze or Duoglaze.

To ensure achievement of consistent quality, specified performance levels and fire certification, we strongly  recommend that only factory installed glazing be used,

Those designated Part M comply with Approved Document Part M, BS 8300 and the Equality Act. Vision panels should towards the leading edge and with vertical dimensions including at least the minimum zones shown, either with or without a horizontal rail.

All entrance doors and doorsets, doors across corridors and within lobbies, and where appropriate internal doors require vision panels for leaves and side panels wider than 450mm.
