Hi, I’m new to the forum and new to home ownership. My husband and I recently bought a home built in 1975. It has thick, painted wood paneling throughout. Part of the house has vaulted wood ceilings and the other part has plywood ceilings. I know many houses from that era and before were built similarly. I’m wondering what can be done to help prevent fast moving fires? I see there is a paint additive that helps resist fire. Do I need to invest in this? I’d hate to paint the beautiful vaulted ceilings. What about investing in a sprinkler system or even just monitored smoke detectors? We are on a budget so that is a factor. Just curious what others have done if anything.
