I have an exterior door way that is plywood and concrete board. I need to cover 2' 6" x 8' will this work outside in extreme cold and extreme heat? Also would I need to buy the 15' roll or do you have short pieces? How wide are the rolls?

Our 8mm Strong Rubber Rolls can be installed outdoors. They are made from the same material your tires are made out of, so they will be able to handle extreme heat and cold. The minimum cut length for these rolls is 15' long and the width of the roll is 4'.
