Hello everyone,
may I ask how you ultimately decided or whether you are satisfied with your decision?
We are facing a similar problem:
4 basement rooms (utility room, workshop, storage, hobby room), all included in the controlled residential ventilation system, 10cm basement insulation, the hobby room has underfloor heating.
Due to water pressure, we want to do without all light shafts.
In the utility room and hobby room we can install normal windows, in storage and workshop no windows are planned.
Now the question arises for us:
The windows are very shallow - giving up the tilt/turn function would give us significantly more glass area. Would you replace the windows with fixed windows?
