Foundation/floor strategy for a heated workshop in Zone 6A
I am planning a 30'x22' farm workshop in Eastern Ontario, Canada. I want to end up with a level floor suitable for woodworking machines (table and bandsaws, planer, jointer etc) , Floor will be on grade, location is on a small rise and I will make sure there is good drainage away from building. I will place 2" of SM insulation under floor. I will most likely frame double stud walls and insulate with 6" to 7" of Roxul.
I will heat with a wood stove and will have 4 x 12sq' windows on the south side. Windows will have heavy curtains for cold nights. I will have one small room inside main room with an electric heater...for storage of paint and frost susceptible products...the main room can go below freezing. Walls will be 10' high with a prefab truss roof. South facing roof will be approx 30'x 15' at angle of approx 40 degrees....I plan to place solar panels one day.
A long description I'm afraid, now the questions.....
1. is a concrete floor the best way to go ?
2. which makes most sense in terms of labour, ease of construction, and cost....full block foundation on concrete footing or 10' sonotube pilings, 10' apart supporting 6"x6" posts, framing in between ?
3. I want steel siding outside and plywood walls inside. I am thinking in order (out to in)....steel siding, nailers, typar, sheathing (1/2' ?), insulation, vapour barrier (yeah, building inspector insists even though this is not a living space), plywood 5/8.
I would greatly appreciate comment, suggestion, or even wild and crazy ideas...thanks,
Mark from Madoc

I am considering getting solar panels on my roof and have quotes from 2 different companies. Is there anywhere I can go to get help on determining which are the better panels?
