I have a spare bedroom that gets a little chilly and it has two crawl spaces with doors on each side of the room. There is insulation in there but not on the ceilings. I was wondering if I should put some sheets of insulation up on the ceiling and if it would help with keeping the room warm. I have attached some pictures to give you guys a better idea of where I am wanting to put insulation. Let me know your opinion guys! Thanks!
