My friend has converted a garage into a music studio. It has a concrete floor with carpet over it. He installed some kind of gas heater that has no vent but does have a CO2 shut off. There is one window that doesn't open. We are still alive so far but that isn't the problem. The problem right now is all the condensation on the equipment. Would an open window solve this and allow the room to dry out? Or would it always be damp.
