Plastic membrane/vapor barrier
Hang up a plumb bob, mark the center, place the tem-
plate and mark up for the hole.
The hole should be cut 30 mm smaller at the plastic
membrane/vapor barrier (see arrow), in order to ensure
a good seal.
Finish with a joint between the duct and the ceiling in the
house.
