Is this a fire hazard??
Our one-story house of about 1600 square feet has a vaulted ceiling in the living room and kitchen, and regular 8-foot ceilings in the rest of the house.
I have been thinking of improving the insulation in the floor of the attic -- the house was built in 1985 and has only the original insulation -- but I'm concerned about 2 things. First, is there a risk that if the new insulation clogs up vents along the edge of the floor of that attic could create new problems. Second, the smaller attic space above the vaulted ceiling poses new challenges -- probably the only new insulation would have to be blown in, and I'm concerned because that might cover over recessed light fixtures, which might then catch fire if they get too hot.
How serious are these risks, and how can I make sure that insulation is installed properly?
