Allen she says "far too much!". And I don't even get a family discount...
Darren, this is step1, step 2 is to put in a drop ceiling of 2" foam at the 10' mark. I'd do 8', but one of my lumber racks is up at 9'
I did a sun survey last week, and it turns out I've been planning on putting my solar heat on the wrong face of the shop. My mostly unfinished end of the shop is the South face, so I'm going to be ordering about 10 sheets of insulation (the drop ceiling) and about another 6 sheets of polycarbonate 'roofing', those plus some 2x6's will allow me to turn the south face into my solar heater for the shop. Doesn't make sense to do that though until the drop ceiling is in, or I'll just be melting the snow off the roof faster. (it already is pretty good at shedding the snow).
