Mike writes from Mount Prospect, Illinois: "I have a family room addition (with a sloped roof) that has no insulation in the ceiling so the heat escapes through the roof. Is it better/easier to insulate from outside, i.e. replace the roof and place foam board or another product on the new roof, or insulate from inside, i.e. fill the spaces between the existing beams of the room's ceiling with insulation and then cover with drywall?"

Answer: I am not sure if your room is finished yet, but if not, I recommend putting up our raft-r-mate product wherever you have soffit vents. You will want to space them one or two inches apart all the way to the top vent. From there you would put in the insulation with paper facing down and finally a fire rated drywall. There is a useful guide which talks about how to install a cathedral ceiling at www.itseasytoinsulate.com. Just click on Easy Weekend Projects and you will see the guide in the bottom left side. There are also videos and a convenient dealer search there. If you do the roof approach instead, I recommend getting a contractor to assist you with that.
