🔍 How to Measure for a Replacement Unit
To order the correct replacement unit, measure the existing glass unit - not the frame opening.
- ✔ Measure the width and height of the existing glass in millimetres
- ✔ Measure the overall thickness of the sealed unit - not just one pane of glass (typically 24mm or 28mm)
- ✔ Note the glass type (clear, frosted, tinted) and any special requirements
- ✔ Double-check all measurements before ordering
If possible, you may remove the unit to measure it more accurately - but this is not always required.
