One pane fogs in a combination
Identify the individual unit rather than measuring the complete frame. Each section can have different dimensions or safety needs.

Fenomax Window Glass Repair in Hamilton
Replacing one foggy pane is not only a sizing exercise. Coating, tint, spacer, grids and reflections affect how the repaired window looks beside the original glass.
Match More Than the Opening
One new sealed unit can stand out in a group of older panes
An existing Fenomax combination window may contain several separate insulated glass units. When only one seal fails, glass-only replacement can preserve the frame—but the new unit should be specified with the neighbouring panes in mind.
Windows Hamilton checks overall thickness, glass treatment, spacer colour, internal or surface grids, safety requirements and the appearance of adjacent units. Exact visual matching cannot always be guaranteed because original coatings and components may have changed or aged.
We provide independent assessment after any applicable Fenomax warranty route has been checked. We do not claim to be the manufacturer, its warranty administrator or a loose-parts retailer.
Confirm Which Pane Failed
A multi-section window contains separate service decisions
Mark the exact pane and photograph the entire grouping so proportions and matching requirements remain clear.
Grid pattern appears uneven
Internal bars, removable grilles and simulated divisions require different matching. Photograph intersections and bar width.
Newer glass reflects differently
Low-E coatings, tint, sky and interior light can change colour and reflection. Review acceptable variation before ordering.
Specify the Visible Details
Glass replacement should respect the whole elevation
The retained frame and sash must be serviceable, and the new unit should be documented for future maintenance.
Sealed-unit replacement
Measure the exact failed pane and record thickness, coating, spacer, gas fill, safety glass and any decorative divisions.
Review sealed units
Grid and appearance review
Compare bar profile, colour and pattern with neighbouring panes. A close match may be possible, but discontinued details should be discussed openly.

Operating-sash assessment
Before reglazing an operable sash, confirm hinges, balances, rollers and locks can continue to support and seal the repaired unit.

Appearance and Condition Both Matter
Do not preserve a failing sash for the sake of one matched pane
The assembly is sound and match is acceptable
A single failed unit can often be addressed independently when the surrounding frame, sash and other panes remain dependable.
- Exact failed section is identified
- Glass specification can be confirmed
- Visual variation is understood
The grouping has broader problems
Consider a complete composition when multiple seals have failed, operating sashes are weak or exterior proportions need to change.
- Several panes show failure
- Frame or sash is deteriorated
- New ventilation or style is desired
Matching Has Practical Limits
Age, coatings and discontinued details affect the result
Even when dimensions are exact, a new pane may look brighter or more reflective beside older Fenomax glass. Spacer technology and grid components may also differ from the original production period.
Photographs help establish the goal, but final decisions should use available samples and documented glass data. If an exact match is essential across a prominent grouping, replacing several related units may deserve consideration.

Photograph the Entire Grouping
Details needed for a Fenomax glass request
Circle the failed pane
Send a full-window photo marked to identify the exact unit that fogs or is broken.
Capture grids and spacer bars
Include close-ups of bar width, intersections, colour and printed spacer information.
Show neighbouring reflections
Take a daylight photo at an angle so differences in tint or coating are easier to discuss.
Test the operating sash
Report whether it opens, stays in position, closes squarely and locks without force.
Match the Pane to the Composition
Request a Window Assessment
Have one foggy Fenomax pane in a larger window grouping?
Send Windows Hamilton a marked full-window photo, close-ups of grids and spacer labels, and the affected pane’s approximate size. We will assess sealed-glass replacement, matching limits and the condition of the sash that will remain.
