We recently installed the panel roof system over the kitchen area and hit the first of our inevitable early-adopter glitches. The roof panels are 11 inches thick and much heavier than the wall panels, as they have much more embedded steel to carry both my green roof and the snow load here in upstate New York. The things are dense and required a serious effort for two to carry around. Even with all that beefiness, the engineer asked me to put a horizontal steel beam through the middle of the room for added support. The panels were supposed to meet at the beam and fit seamlessly together. The key words there: supposed to. Read on for the reality.
I know being the first to use any technology comes with trade-offs, and I’d rather have a bit of fit-up trouble to get a roof with an R-value, a measure of thermal resistance, of 52—several times the typical roof. But that’s little consolation when your arms are burning as you pound the umpteenth panel into place. Fortunately, the company is sending out its own team next week to do some panel remaking in the field. Then we should be back on track.
