do not want to ruin the plaster or take up the flat roof…….but the temperature in florida gets very hot and need to get it insulation
I wanted to use foam but cant find a way
or want to blow in cellulose
if anyone has an idea
please let me know please
What is your ceiling height? if you have sufficient clearance, you could construct a dropped ceiling with insulation between it and the original ceiling.
