Most doors are designed to look as though they're made from wood, even if they're not. Non-wood materials such as steel and fiberglass are excellent at simulating the look of wood yet are more affordable, have a greater insulation value and require far less maintenance.
All-wood doors are made from softwoods or more durable and elegant hardwoods. Fiberglass-composite doors, made from a core of rigid insulation clad with a fiber-reinforced polymer, are often embossed with artificial wood grain so they look like wood. Steel doors, made of heavy-gauge, galvanized steel over a core of rigid foam, are strong but do a less convincing impersonation of wood. Their surfaces are typically coated with polymer or vinyl and are wood-grain embossed. You can also buy exterior doors made from solid wood (planks or blocks glued together and sanded), veneer applied over solid wood or veneer applied over a hollow-core.
Standard doors are 6-foot, 8-inches tall and vary in width from narrow 12-inch-wide cupboard doors to 8-foot (or wider) sliders.
