I AM INTERESTED IN YOUR 20 FOOT. WILL THE COLD MAKE THE PVC .HOW WELL WILL IT TAKE SNOW
It will not hold much snow with out heat to melt it off. Extreme cold will stiffen the PVC poles some but the dome is till use able (do you plan to put it up and down a lot in the cold? If so I would order it with out the vinyl windows as they are stiff in the extreme cold.
