Thanks, it will be a while before I do that install... at my snail's pace there's a long list of home improvement projects lying in wait. It's more a problem of procrastination, I suppose.
The patio is completely enclosed, albeit well ventilated wiht one wall made of simple corrugated green fiberglass above, and glass jalousie windows (with 1" gaps above and below) beneath. There's a wall heater in there but I've never activated it (it needs a new thermocouple or something) because it would have to run continuously to make much of an impact in the dead of winter. It does stay about 10 degrees warmer than the surrounding outdoors - so it can dip into the 40's but generally stays in the 50's or above. So it doesn't get a LOT of use in the winter, though it's nice to be able to BBQ stuff in the covered patio just outside the enclosed patio... confused yet :0?
Today at work I made a resolution to clean up all the clutter. Whoops, I may have to be off-line for a couple of weeks!
