The creation of a masterpiece
     Each JELD WENŽ Wood Window and Patio Door is fashioned from preservative-treated, precision-milled western pine. There's an unmistakable warmth and durability infused in this wood, making it a natural choice for JELD WEN products. As JELD WEN artisans create, they unite beauty with strength. They follow standards to ensure each window and patio door is architecturally correct. They also test and refine the result, so you can be confident that each will exceed your expectation tomorrow, as well as today. The results of all this care are not only artful in appearance, but masterful in performance.

MW's "Twinseal" design is fully welded construction, utilizing a distinctive narrow line profile for a classic double hung appearance. The 3/4 inch Warm-Edge Insulating Glass provides energy efficient performance in all seasons, all regions. You can also visit the MW Window company web site for more info.
