As summer heat lessens during the next couple of months, you'll want to air out the house. You hope to bring in a summer breeze, but you want to keep your home clean. Let fresh air in and keep insects, leaves and other yard debris out with adjustable window screens by W.B. Marvin, Frost King's own product line of adjustable replacement windows and slide-to-adjust screens. W.B. Marvin is the leader in adjustable screens made to fit almost any window. Founded in Urbana, Ohio in 1915, The W.B. Marvin Company introduced its first metal rail adjustable screen in 1936. This screen was marketed to let fresh air in and keep bugs out. Windows featuring the iconic W.B. Marvin screen were soon found in homes throughout the U.S. In 2008 W.B. Marvin joined the Frost King family when our parent company Thermwell purchased the entire line of window screens and added the W.B. Marvin catalog to Frost King's product line. These classic and durable adjustable window screens have been made in the U.S.A. since day one. Watch how we make the W.B. Marvin adjustable window screens in our Ohio factory. Frost King recently upgraded its original screen making factory to a new 10,000-square-foot manufacturing facility in Urbana, Ohio. At the new operations, W.B. Marvin will continue to be a leading manufacturer of adjustable replacement windows and adjustable window screens. Adjustable window screens are easy to install and easy to remove, making them perfect for our do-it-yourself enthusiasts. No tools are needed. Window screens are made with two screens that slide overtop of one another. Simply slide one out to adjust it to fit your window frame. Frost King provides original W.B. Marvin adjustable window screens with aluminum screening, wood ends and plated easy-gliding steel rails for fingertip adjustment. Find out where to buy W.B. Marvin screens.
