This knotty alder double entry door is designed around a full-lite glass design, setting a welcoming tone the moment guests arrive. It is crafted 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 the insulated, tempered glass adds strength, safety, and a quieter interior. Inside, engineered stiles and rails give it dependable strength and help it stay true through seasonal changes. Finish it your way with stain or paint, or skip the work and have it pre-finished so it shows up sealed, protected, and ready to hang.
