Colorado’s extreme weather conditions require windows and doors that will last. Infinity’s Ultrex® fiberglass is the most durable window and patio door material in the industry. The strength of Ultrex® means no warping, cracking, or premature failure of the frame. Ultrex® is so strong…we guarantee it, for life.
Ultrex® fiberglass is far less thermally conductive than aluminum and insulates much like wood. In fact, all Infinity products are ENERGY STAR® certified. This means your new Infinity patio doors will provide an insulating barrier against extreme weather, keep your home comfortable and reduce your utility bills.
