Hello!
I'm working on a small garage where I will have a PAX fan for mechanical exhaust.
The frame is made of wood, and the inside is clad with OSB and plasterboard. The outside is made of horizontal paneling.
I would be very grateful for any tips on what is used as a wall penetration?
I guess one uses some form of pipe, perhaps a 110 pipe like the ones used for drainage?
Best regards,
Fredrik
