We have designed a garage-->family room conversion (don't worry, they are adding on a much nicer garage) for a client. The new family room will have a "tray ceiling." After our clients thought about it, they decided they were going for more of a "cathedral ceiling" look. I am not partial, design wise, to either one. My only hold up with a cathedral is insulation. It is very hard to squeeze in the correct R-value into a cathedral ceiling. In fact, the term "squeeze insulation" makes building science nerds, like myself cringe...DON'T EVER SHOVE INSULATION INTO ANY AREA, any insulation material's R-value is only valid at its recommended fluff depth (that is my technical term.) If anyone has more questions about that I am happy to elaborate, but for, now onto the fun stuff. We came up with a insulation value solution by making a lesser pitched roof on the interior of the roof to give it a cathedral ceiling look while allowing for plenty of insulation up there. Problem solved?
Before we went too far with determining how beams and load values work out, we decided to make sure there is no communication barrier. So I am searching for picture examples of each (my job IS fun!)
