Did we really need to insulate the ceiling?
We live in a 100+ year old brick townhouse with an unfinished basement, partially above grade. The walls are painted masonry. The ceiling used to be drywalled, but our contractor tore out the drywall when we had the house gutted 7 years ago for renovation to run new electrical and plumbing. The basment is dry with no mold problems, though we do run a humidifier in the summer. In winter, the basement is quite comfortable, I assume because of the hot water pipes running just below the ceiling joists (we have hot water radiators).
My husband recently insulated the ceiling. Now it's hot as Hades down there. Was this a mistake? Please advise!
