2. Ultrex is a superior window material, outperforming vinyl, roll-form aluminum and other window materials in every way. Ultrex is strong as steel, eight times stronger than vinyl, and three-and-a-half times stronger than wood/vinyl composites. It has a very low rate of temperature transfer, and its tendency to expand and contract is seven times less than vinyl keeps the window stable and weathertight. Ultrex is virtually maintenance free, and won’t rot, warp or dent.
