This knotty alder entry door is designed around a three-quarter lite glass design, giving the front of your home real presence and curb appeal. It is crafted from knotty alder, a warm, characterful wood whose natural knots give every door a one-of-a-kind, rustic personality. The glazing fills the space with natural light without sacrificing the door's solid, substantial feel, and the insulated, tempered glass adds strength, safety, and a quieter interior. It is built around engineered stiles and rails for lasting stability and everyday durability. Leave it unfinished to stain or paint to your taste, or select the pre-finished option and save yourself the time, mess, and guesswork on site.
