My bathroom is above my garage. The water pipes have frozen and I'd like to have the ceiling in the garage better insulated. I'm getting conflicting information:
Some say to insulate the ceiling below the pipes so that the pipes retain the heat from the interior of the house.
Others say this is hogwash, and that heat rises, and that the best (for a finished ceiling) is to blow in cellulose and block all air movemement, thereby insulating the pipes from everything.
Thoughts from the experts?
I'm also planning to install a 220v electric heater as extra insurance (excuse to run 220 to my garage for some tools).
