What is a Masonite door?

A Masonite door is a door manufactured by Masonite International, one of the largest door manufacturers in the world, offering interior and exterior doors made from various materials including molded wood composite, steel, fiberglass, and solid wood. Masonite was founded in 1925 by William H. Mason, inventor of hardboard, and is headquartered in Tampa, Florida. Masonite interior doors include molded panel doors that are made by molding wood fiber and resin into panel designs like 6-panel, 2-panel, and 3-panel, offering affordable durable interior doors at 50 to 150 dollars, plus flush doors and solid core options for better sound insulation. Masonite exterior entry doors include steel entry doors with steel skins and foam core for security and energy efficiency at 200 to 500 dollars, fiberglass entry doors with wood grain texture that can be stained at 400 to 900 dollars, and wood entry doors. Masonite doors are sold at Home Depot, Lowes, lumber yards, and dealers, known for good value, wide availability, and many styles. Masonite doors have limited lifetime warranty for many lines. Masonite is not a type of hollow door only, it offers both hollow core and solid core interior doors. So a Masonite door is a brand of door, not a material, offering many door types for interior and exterior use.
