Duratherm has developed a reputation among architects who appreciate the company’s specialty: custom wood windows with two species on one frame. Other features include extruded silicone gaskets, removable interior glass stops, and silicone weather stripping. The windows—seen here on a Bamesberger-designed house—can be produced with frame depths of up to 10 inches in almost any wood. Duratherm Window Corp., 800.996.5558; www.durathermwindow.com.
