This knotty alder entry door is designed around an arch-top glass design, giving the front of your home real presence and curb appeal. The door is built 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 insulated Low-E glass adds year-round comfort and better energy efficiency. It is built around engineered stiles and rails for lasting stability and everyday durability. Order it unfinished to stain or paint yourself, or opt for a factory pre-finished unit that is ready to install the moment it arrives. You can build out the full entryway by adding matching sidelites on both sides and a transom above.
