Masonite Doors
Interior and Exterior Doors Built for Everyday Comfort and Lasting Performance
Masonite’s story began in 1925, when inventor William H. Mason opened his first plant in Laurel, Mississippi, to produce a new wood-fiber hardboard he had developed. A century later, Masonite is one of the best-known door manufacturers in North America, making fiberglass and steel exterior doors as well as molded panel and solid core interior doors. The company is headquartered in Tampa, Florida, and has been part of building materials leader Owens Corning since 2024.
At American Window Company, we’re proud to offer Masonite doors to homeowners throughout Southern California. Whether you’re replacing a weathered front door or upgrading every bedroom door in the house, our team can help you compare styles, materials, and glass options, then handle the installation from start to finish.

Masonite Door Options for Every Room
Masonite makes doors for nearly every opening in your home, from the front entry to the home office.
Fiberglass Entry Doors
Masonite fiberglass doors won't rot, warp, or crack like wood, which makes them a great fit for the Southern California sun. Each has an insulated foam core between two fiberglass layers. Styles range from the craftsman-inspired Winslow and Shaker-style Lincoln Park and Logan to VistaGrande flush-glazed doors, which let in more natural light than doors with traditional glass frames.

Masonite Performance Door System
Masonite's fiberglass front doors are available as part of the Masonite Performance Door System. Its 4-Point Performance Seal combines a square-edge door, a self-adjusting sill, adaptive weatherstripping, and enhanced corner pads, and the system adds a rot-resistant frame that won't wick water, swell, or mold. According to Masonite, the system is 64% better at keeping air and water out than the leading competitor. For added security, it can be upgraded with Masonite's M-Protect multi-point lock.
Steel Exterior Doors
Masonite steel doors are a cost-effective way to add strength and security. Decorative panel profiles give them the look of a higher-end door, and they're a practical choice for front entries, side doors, and house-to-garage openings.
Patio and French Doors
Masonite patio doors bring in natural light and connect your living space to the backyard. Swinging patio doors, including French-style double doors, offer a classic look and a wide, welcoming opening for indoor-outdoor living. Many Masonite front and patio doors are also ENERGY STAR certified, helping keep your home comfortable through hot Southern California summers. Explore more options on our patio doors and French doors pages.
Interior Doors
Masonite interior doors include panel styles like Logan, Lincoln Park, and Livingston, along with French, barn, and bifold doors. Many are available with solid core construction, which Masonite says manages sound better and is more durable than hollow core. It's a smart upgrade for bedrooms, bathrooms, laundry rooms, and home offices.
