This knotty alder entry door is designed around a two-panel design, making a warm, confident first impression at your entry. The door is built from knotty alder, a warm, characterful wood whose natural knots give every door a one-of-a-kind, rustic personality. Inside, an engineered laminated veneer lumber (LVL) core and engineered stiles and rails work together to deliver strength, stability, and resistance to warping over the long term. 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. It is a simple way to lift the look of your home's exterior.
