What's involved with fire door vision panels in Harpenden

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.

  • Vision panel kits from the door manufacturer where available
  • Like-for-like fire glass replacement in vision panels
  • Photographic records for your fire door log
  • Correct glazing seals and bead profiles

Key checks for Harpenden projects

The commonest fault

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.

Cutting new panels

A new aperture can invalidate a door's certification unless the manufacturer's instructions allow it. We check before cutting.

Inspection follow-up
