  Introduction

When Georgian and other period buildings undergo refurbishment or a formal change of use, the level of fire safety protection must frequently be improved to meet modern fire safety standards. Unfortunately it is not possible to fire rate the small panes of glass fixed into thin glazing bars characteristic of the Georgian style because these are consumed so rapidly during a fire. Sealmaster GB15 Glazing Bars avoid this problem, giving glazed doors or partitions a georgian appearance - with a fire rating of 30 or 60 minutes.

The glazing bars are fixed to each face of larger panes of Pyran S glass in a lattice framework. To prevent the heat radiated by a fire from igniting the beads on the unexposed side, the bars automatically detach in the first few minutes of a fire - forced away from the glass by strips of intumescent compound which swell under heat to produce the required pressure. The large pane then reverts to provide 30 or 60 minute protection (depending on the FireGlaze system used to protect it).

  Options

Suitable for glazed fire doors and fire rated glazed screens where 30 or 60 minutes of protection is required. For details of the edging detail, see the other pages in the Fire Glazing Seals section.

  Features
  • Automatically self-detaching during a fire.
  • High pressure graphite-based compound.
  • Excellent longevity characteristics.
  • Hardwood bars may be decorated or stained.
  Components

The FireGlaze intumescent seals used in glass doors typically include three key components - FireGlaze Compound, FireGlaze GR15 dry bead strip and Ultima fire and smoke seals.

  Installation

The construction and installation of glass fire doors is generally carried out by specialist fabricators. Sealmaster's technical engineers are available to advise on the use of FireGlaze intumescent protection.

  Test Evidence

The doors have been independently proven to meet BS 476: Part 20-23 1987. Copies of test certificates, reports and assessments are available for inspection.
