Wall Insulation – I’m Hot/Cold!
I own a single-story home in Livermore, CA, that was built in 1964, and it can get quite warm/cold in summer and winter. I’d like to check into getting insulation blown into the walls prior to having the exterior painted. Is there a way to determine if there was insulation used when it was built? Could I go ahead and have insulation blown into the walls if there is any existing insulation? I’d appreciate any advice/recommendations you could provide.
