Hey Friends!
I’m preparing to replace all the interior doors in my apartment (Chicago), and I am wondering if the laundry and furnace rooms require special doors.
Ideally, I would love to slap some solid core doors on there to reduce sound, but it’s unclear to me if I need to install doors with ventilation, and if so, how much.
Does anyone know what best practices are here?
Thank you all <3
Replace what you have with similar is usually logical. Modern laundry usually has a vent, so at least a gap at the bottom of the door is necessary. Furnace room will have more important code requirements. Old furaces and water heaters drew air from the room. That’s no longer allowed in new appliances. So if they do draw from the room, you must have ventilation. If not, it doesn’t matter / isn’t required. Either way, that doesn’t prevent you from installing solid doors. Also, you can vent through the interior wall if you don’t want to cut into your door.
