Condensation in ventilation - insulate the pipe?

[Hemtomten]

Hi!

We are having issues with condensation in the kitchen ventilation. The house is a split-level, and we have a cold attic above the kitchen. I suspect it might be about insulating the duct. If it usually helps, I would be very grateful for advice on the best way to do it.

Attached is a picture of the ventilation up in the attic (no fan or vvx is connected to force the air).

Many thanks in advance!

Use this with binding wire and tape to prevent condensation from dripping down into the fan.
