The plastic at the chimney.

How do you handle the diffspärr around the chimney when going out through the outer roof?

Murad chimney or sheet metal module?

And you mean the inner roof, because that's where the diff lock is located, right?

I have insulated my metal chimney with a 30mm mesh mat where it goes through the roof, the plastic against the mesh mat, got approved by the chimney sweeper.

It is a plåtmodul and yes the diffspärren is closest to the glesen in the "outer roof"

I bought my modular chimney in a complete kit. There was a special rubber membrane that you slipped over the chimney and taped with special tape. Then you taped the edges of the rubber membrane to the vapor barrier.
