Listings commonly offer frosted/privacy glass that diffuses light while blocking visibility and Low-E tempered glass that adds thermal insulation, UV protection, and improved sound resistance.
Most 36" x 80" finished doors in these listings pair with a 38-1/4" x 82-1/8" rough opening and a 4-9/16" finished door frame.
Listings commonly note reinforced LVL or laminated plywood frames, waterproof and dent-resistant door panels, and finish processes (such as through-dye or full-color penetration) designed to resist fading and scratches.
Some listings call out Low-E (low-emissivity) tempered glass, which the listings state provides improved thermal insulation, UV protection, reduced sound transmission, and better resistance to condensation and far-infrared heat transfer.
Most exterior or pre-hung listings show a 36" x 80" finished door panel (often paired with a 38-1/4" x 82-1/8" rough opening); at least one interior slab listing is around 24" x 80".
Some listings advertise complete pre-hung packages (door panel plus frame) and explicitly list included hardware such as hinges, threshold, brickmold, and sill; other listings state they sell only the door slab and exclude frames, tracks, or hinges.
Listings describe pre-primed, paint-ready panels (some note light sanding before painting) and triple-layer primed panels; at least one interior door is described as pre-painted and ready to install.
Some door slabs are described as double-packaged for safe delivery, arriving in an outer cardboard box plus an inner bubble-wrap layer reinforced with metalized or metal paper to protect the panel.
