Customer asked about improving ventilation in laundry room with a fixed, non-opening window at lovely cottage house.
The existing aluminium mono-frame system didn’t leave enough room to drill and fit a standard face-fixed trickle vent. The sealed unit had already failed so I ordered a new double glazed unit with reduced height and installed an overglazed trickle vent above the glass.
Result:
✔ Improved airflow and ventilation
✔ No modification or damage to the original frame
✔ Fresh new sealed unit installed at the same time
