Are Masonite doors solid or hollow?

Masonite doors can be both solid and hollow depending on type, as Masonite offers interior doors in both hollow core and solid core construction, plus solid fiberglass and steel entry doors. Masonite interior molded doors are commonly available as hollow core, which are lightweight doors with honeycomb cardboard interior and molded wood composite skins, costing 50 to 100 dollars and suitable for closets and low-traffic areas where sound insulation is less important. Masonite also offers solid core interior doors, which have particleboard or wood fiber core that provides better sound insulation, heavier weight, and more durability, costing 100 to 200 dollars and recommended for bedrooms and bathrooms. Masonite solid core doors are considered better quality with better sound ratings. Masonite entry doors including steel and fiberglass entry doors are solid with foam core insulation for security and energy efficiency, not hollow, with thickness 1-3/4 inches. So Masonite doors are not exclusively hollow, they offer both hollow core and solid core interior options, plus solid exterior doors. When buying Masonite interior doors at Home Depot or Lowes, check product description for hollow core versus solid core, as both are available and price differs. For best sound insulation, choose solid core Masonite doors.
