The most outstanding feature and benefit of any fiberglass door is the strong dimensions of depth and crisp shadow lines, which is what gives fiberglass the aesthetic advantage over steel. This is where the Timberline series of fiberglass exterior doors are unsurpassed. The Timberline series of doors also had a unique “Square edge design” which give true wood door appearance. With the full-length composite stiles, and top/bottom rails, Timberline fiberglass doors are the best alternative to a real wood door. With the patented adjustable hinge system that allows the door to be adjusted in and out, up and down, even after final installation of the frame (in order to compensate for walls or floor that are not completely square or level) the Timberline Fiberglass door is THE fiberglass door. Preferred Window & Door offers these doors with an array of glass options and also factory prefinished stain or paint options.
