When visiting my friend in her apartment the other day I noticed how large of a gap there was between the apartment doors and the floor. It was more than a half inch! Besides the lack of privacy, these large gaps let their heat into the hallways in the winter and the cool air into the hallway in the summer. What a waste?!
My friend bought a draft-stopper under her door. It eliminates the drafts and saves her money on her utilities. There are many different types of these available. If you have a drafty door these products will save you money!
