Marvin Windows and Doors has added a sliding patio door to its Integrity line of windows, made with parts pultruded at Tecton Products in Fargo, N.D.
Marvin calls the pultruded components Ultrexe. Tecton pultrudes the parts using glass fibers pulled through a polyester resin.
Ultrex cladding is used on the outside of the doors.
Marvin, based in Warroad, Minn., also has added a round-top window to the Integrity line.
