we are currently installing a wood stove in our prefabricated house.
Our chimney installer has fitted a wall penetration for the flue pipe into an exterior wall (timber frame wall).
Our wall structure is such that on the inside of the wall, there is a 12.5mm (0.5 inch) drywall panel followed by a 16mm (0.63 inch) wood-based panel (OSB).
Between these layers, a vapor barrier membrane is installed.
Now our chimney sweep says that a 100 x 100 cm (39 x 39 inch) heat shield panel (20mm (0.8 inch) thick) needs to be installed in front of the wall penetration.
This panel would then replace the drywall and wood-based panel at that spot.
Can I then apply the vapor barrier membrane onto the heat shield panel instead of the original OSB panel?
And then install a (thinner) drywall panel on top so that the wall surface remains flush?
Or is it generally not allowed to run the vapor barrier all the way up to the flue pipe because of fire safety concerns?
Maybe the vapor barrier is no longer necessary at this point due to the presence of the heat shield panel, as the wall might already be sufficiently sealed in this area.
Thank you very much & best regards
Michael
