Hello everyone,
I recently joined this forum because we are currently quite frustrated with the topic of ventilation.
Our construction project starts at the end of April.
It is a solid brick/Poroton house, a single-family home with 200 m² (2,150 sq ft) of living space on two levels. KfW 55 energy standard.
I can’t really explain it, but I can’t decide on a central ventilation system because of the long duct lengths inside the house. I know that all pipes are clean and protected by filters, but my gut feeling just doesn’t agree.
With decentralized systems, we are bothered by the fans on the exterior walls in every room.
Now we are looking for an alternative.
We also didn’t find window frame ventilators very appealing.
So my question is:
Has anyone else experienced this or does anyone know of another system?
We learned about a system available through Baufritz houses with air transfer grills. However, it is only distributed through Baufritz.
It’s a central ventilation system that blows air directly into the house over a short distance and then distributes it further via transfer grills above the doors.
I look forward to your input and help.

I would not necessarily position the outlets and inlets directly in the main wind direction.

Plastic is not always the same. So which type? If you want to be on the safe side, go with metal.Honestly, no idea... We will be meeting with our ventilation specialist at the end of this week. Apparently, plastic costs about €1,000 (around $1,100) more. But you think metal is the safer choice? What are the differences here?

But you mean – with metal sheets, you can’t really go wrong? What are the differences here? Using plastic (more common than metal sheets) is also a safe choice. The perfect is the enemy of the good. KfW 40+ is better than KfW 40, which is better than KfW 55. All are well established and work reliably.
So if metal is even cheaper, then there’s really no need to think twice. You can’t go wrong with that; in fact, you’re making the right choice in many ways.
In my experience, plastic is often used simply because it is cheaper than metal and offers a higher profit margin for the ventilation installer.
I wouldn’t give it much more thought.
