What the glass problem looks like

  • Cracked or shattered GPW wired glass in an existing door vision lite, sidelite or fixed steel frame.
  • A solid steel or hollow metal door that needs a new vision opening and compatible lite kit for improved sightlines.
  • Uncertainty about whether the existing panel is GPW, Georgian wired glass, another wired product or a different listed glazing type.

What we replace or install

  • Inspection of the glass pattern, door or frame, labels, stops, lite kit and opening use before replacement or modification is recommended.
  • Removal and replacement of damaged GPW or wired glass when the existing frame or vision kit remains suitable.
  • Door cut-out and vision-lite preparation only where the door, listing, lite kit and opening requirements allow that field work.

Glass-only replacement is likely when

Glass-only replacement is appropriate when the existing door, frame, lite kit and opening remain compatible and serviceable.

A larger door, window or frame scope may be needed when

A broader fire-rated, steel-door or frame service is required when the listed opening or supporting system is also failing.

Questions about GPW & Wired Glass Replacement & Installation

What does GPW glass mean?

GPW commonly means Georgian Polished Wire glass, also called Georgian polished wired glass. It has a visible square wire mesh and is used in some commercial doors, fixed steel frames and listed specialty openings.

Can broken GPW glass be replaced without changing the full door?

Often yes, when the door, lite frame, stops and surrounding assembly remain serviceable. We check the existing opening before confirming glass-only replacement.

Can you cut a steel door and install a new GPW vision lite?

Sometimes. The door construction, labels, listing, opening size and compatible lite kit must allow the modification. Not every steel or fire-rated door can be field-cut.

Where is GPW wired glass commonly used?

It can appear in door vision panels, sidelites, corridor windows, service-room openings, partitions and fixed steel-frame windows. The required product depends on the listed assembly and the opening conditions.

Is wired glass unbreakable or automatically safety glass?

No. Wired glass can break and should not be described as unbreakable. The correct glass depends on the opening, applicable requirements and the listed assembly or product being matched.

I hired DoorWin services to replace two cracked glass windows for a unit at my triplex. An exterior porch window and interior stairwell window I just needed the panes of glass replaced and not the entire frame . DoorWin was happy to do the job. Unlike some other companies who wanted to replace the entire frame at a higher cost. They were very quick with a quote and were able to perform the job on an extremely tight timeline that I had to unexpectedly move up. Very professional. Friendly. Dependable. Competitive prices. Took away all materials and left a clean worksite. Would highly recommend and will work with them again if I need another window repair.
