This speakeasy knotty alder entry door pairs an arch-top glass design with two raised lower panels with thoughtful proportions, making a warm, confident first impression at your entry. It is crafted from knotty alder, a warm, characterful wood whose natural knots give every door a one-of-a-kind, rustic personality. The glass invites natural light deep into the space while keeping the door feeling open and airy, and the energy-efficient Low-E glazing helps hold comfortable temperatures and lower heating and cooling costs. 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.
