Scumbria, 6" roof joists? That is quite thin, of course you have zero snow load. Here we have a 100 pounds per square foot snow load to design for. I have never seen such a winter. 100 pounds per quare foot is 18" of standing water or 200 inches of snow. If you are a long temr resident you might consider blown in fiber fluff insulation for the walls and ceiling. It will sva eon heat and air con. Here we have business whose entire basis is blown in fiberglass or shredded paer or assorted foams. There? Well as gas/volts go through the roof the incentive to insulate will grow and it will justify people entering that business. Bill

Dear Scumbria: I live in Wisconsin. We just had 6" of snow. I worked 3 weeks out in the Bay area on a warehousing project in February of last year. By my standards, it was typical September weather for my hometown, highs in the 60's and 70's with lows in the 30's and 40's. 2" of foam insulation can have a R value of 20. If the walls are nothing more than 2x4s with two pieces of wallboard (plaster) on them and as cheaply constructed as that, foam filling it should be a snap. Do not forget that you can replace the windows with triple pane low-e glass. You could have the roof foam filled. The R value of an empty 2x4, really 1.5"x3", built wall is about 7-10. The reason foam filling works is it reduces convection currents inside the walls and any air infiltration (drafts). Doing the above, can cut your heating and cooling bills by as much as four times (1/4). The building in silicon valley are built to such low standards that most of them would be condemned in anywhere in Wisconsin. By the way, a basement acts like a high thermal mass to average out the peaks and valleys in temperature (here the ground temperature (below the permafrost level) is about 43 to 46 degree Fahrenheit).
