Are they in the preferred fixing position for the secondary window? In which case can they be removed completely? If not, consider:

  • Adapting the fan to fit within the secondary glazing.
  • Providing a new fan which can be fitted within the secondary glazing.
  • Designing the secondary glazing to fit around a boxed-in fan.
  • Relocate the fan through a wall.

Note:
1. Retention of a fan will reduce the potential for noise insulation.
2. When the fan is fitted within the secondary glazing it is recommended that the glass is toughened.
