If you are a do-it-yourselfer who really wants to create a cathedral ceiling, you will find it very easy to do with vented insulated roofing panels. These panels provide outstanding insulation value (as much as R40), include spacers for venting, and are easy to nail in place. Some of the panels, called strong stress skin panels, have either wood paneling or drywall already attached. You will find it easy to construct your cathedral ceiling and provide extra room insulation very quickly.
