I live around Buffalo NY and have a garage studio...
I worked last year through December in my uninsulated garage. I threw in the towel when my beads were shocking from the torch into the kiln. The kiln was right next to me.......
I am watching this thread hoping that someone has a fantastic solution that doesn't cost a fortune to implement.
Good luck and have fun,
Joan
PS
There is an awesome thread by DeAnne ( The Glass Zone) about piping your propane from outside to your torch. That was so very helpful!
There is a wealth of info here and so many generous people.
