Wired Glass Replacement
Replace old Georgian wired glass with modern fire glass.
Learn more →A fire door vision panel is the glazed opening in a fire door that lets people see through it. It is part of the door's fire rating: the glass, beads, glazing seals and the size and position of the opening all have to match the door's test or certification evidence.

We replace broken, missing and non-compliant vision panels, upgrade old wired glass, and correct beads and seals that have been fitted wrongly. Where a new vision panel is needed, we only cut it in where the door manufacturer or certification scheme allows it.
Missing or wrong glazing seals and loose beads are among the most frequent defects found in fire door inspections. They are quick to fix properly once the door's specification is known.
Ordinary float or toughened glass in a fire door vision panel is a serious defect. We replace it with fire-resistant glass compatible with the door.
A new aperture can invalidate a door's certification unless the manufacturer's instructions allow it. We check before cutting.
Old wired glass often provides integrity but not impact safety. Upgrading to modern fire glass with an impact classification removes a common risk in schools and corridors.
If your fire door inspection report lists vision panel defects, send it to us and we will quote item by item.
We photograph each panel before and after and note the glass marks, so your fire door records stay complete.
Single vision panel replacements from £185 per door supplied and fitted, excluding VAT. Prices depend on the rating, pane sizes, frame system, access and programme. Use the guide price tool for a range, or see all guide prices.
Yes. The replacement must be fire-resistant glass of a type the door's evidence allows, fitted with the correct beads and seals.
Not always. Building guidance expects vision panels in doors that subdivide corridors and in double-swing doors, and accessibility guidance favours them in many circulation doors.
Only under the door manufacturer's or certification scheme's instructions. Otherwise the door's rating may no longer be valid.
It may provide integrity, but it often fails impact safety requirements. Replacement with modern fire glass is usually recommended.
Once we know the door type and glass size, standard integrity panes can often be supplied quickly; insulating glass may take longer to cut to size.
