Cab in progress

i personaly would go with what is called tractor glass my father owns a skid steer and he tried plexiglass it cracks in winter and it attracts alot of dust. tractor glass spiders but wont break. my fathers skid steer has runn two years with a hole in on of the windows that he made. a cut off tree limb went through the side stopping just short of his head. all we had to do was just lightly push the glass back in place and it has stayed in place ever since.
thats what i suggest really neat glass it has layers of plastic integrated into the glass to keep it from completly shattering.

I bet if you had painted the top black, you wouldn't need a heater. Maybe mount solar hot water collector on roof, with fan motor inside to blow hot air into cab thru a vent in top.

that would work well if you didn't have minus figures here in canada it would do bubkis because we get minus fourty regularly especialy in january.
