This knotty alder entry door pairs a glass design that opens to natural light with two raised lower panels with a clean, considered profile, setting a welcoming tone the moment guests arrive. The door is built from knotty alder, a warm, characterful wood whose natural knots give every door a one-of-a-kind, rustic personality. Daylight pours through the glass to brighten the room and make the entry feel larger and more welcoming, and insulated Low-E glass adds year-round comfort and better energy efficiency. Structurally, it relies on an engineered laminated veneer lumber (LVL) core and engineered stiles and rails for dependable strength and lasting stability. 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.
