Hello everyone,
I understand that controlled residential ventilation systems require ventilation gaps for air exchange, which makes sense. We have two glass doors, and it is clear that maintaining the required gap height is not possible; the door will be as tall as possible.
We have a list with the specified dimensions outlining the requirements.
What are your thoughts on the assumption that a gap is present but does not always meet the required height? For some doors, a gap of 1.4 cm (0.55 inches) is required, which is quite a significant height.

From a purely visual perspective, at least for me, that is the case.
That’s why I’m also asking for reasons why it’s so important to strictly follow the height measurements.
What could happen...
Or if it might not make any difference at all...

Before installation, we routed the door frames on both sides about 10mm (0.4 inches) wide in the non-visible area at the top, allowing air to flow there in addition to the few millimeters under the door. This is not visible, ensures air transfer, and makes it more difficult for sound to pass through because it has to navigate the "labyrinth" created by the frame and door lintel.

So air can flow through there as well.
I’ll see how I’ll handle that.
@One00: About how wide is the gap under your doors?
