Vision panels.

Glazed vision panels are often used within door leaves to let light into a room, for aesthetic reasons or for safety (i.e. allowing people using the door to be seen).

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 opposite.

Alternative designs can be accommodated and these should be discussed with us at an early stage as shape, size and position to your choice is subject to certification parameters.

All aperture dimensions shown in this section relate to cut out size. To ensure achievement of consistent quality, specified performance levels and fire certification, we strongly recommend that only factory installed glazing be used.

Those designated comply with Approved Document Part , BS 8300 and The Equality Act. Vision panels should be 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 door leaves and side panels wider than 450mm.

Acoustic doorsets can accommodate many of our standard vision panel designs – all factory glazed (with glass to suit acoustic and fire performance) using fully sealed glazing beads. Glazing generally has a lower acoustic performance than the door (maximum 40RwdB) and will reduce overall performance, directly in proportion to the amount of glazing used. It is therefore recommended to minimise glazing in acoustic doorsets. Contact our Technical Services Team to discuss your design requirements.
