My neighbor was right about that old insulation trick
When we bought our 1950s bungalow in Decatur, Mr. Henderson next door kept insisting we keep the original rock wool insulation in the attic. I thought he was just being old-fashioned and we spent $1,200 to have it all removed and replaced with modern fiberglass. Three winters later, our heating bills are actually higher than his, and I found out rock wool is fireproof and works great. Now my attic has these new batts that settled after 6 months and left gaps near the eaves. Has anyone else regretted ripping out original materials from an older Atlanta home?
