Hello everyone!
Our ventilation system (Zehnder) is installed in the attic.
The attic is insulated with 160mm (6 inches) of compressed mineral wool.
The ceiling below is also insulated, I believe with 240mm (9.5 inches) of compressed mineral wool.
The DN75 (3-inch) pipes running from the ventilation system to the rooms are simply laid on the roof boarding.
Do these pipes need to be insulated?
The attic is NOT heated. The rooms below, of course, are heated...
Our plumber says that the pipes do not need to be insulated.
What do you think?

I don’t understand either how you can have 0°C (32°F) outside and 19°C (66°F) in the attic without heating.The roof is insulated as well, I wanted to mention that. At the same time, I was looking up the construction by Schwörerhaus but then got distracted.Similar topics
