Is Masonite still sold?

Yes, Masonite is still sold and remains one of the largest door manufacturers in the world, though the original Masonite siding is no longer sold. Masonite International, headquartered in Tampa, Florida, is a publicly traded company that sells millions of interior and exterior doors annually through Home Depot, Lowe's, and dealers across North America. The brand Masonite today primarily refers to doors, not siding. Masonite interior doors, which are molded MDF hardboard doors with hollow or solid core, are widely sold at Home Depot as the most common interior door option, costing 100 to 300 dollars. Masonite exterior fiberglass and steel doors are also sold. However, Masonite hardboard siding, which was popular in the 1980s and 1990s, was discontinued due to class-action lawsuits over rot and swelling issues, and is no longer manufactured or sold as Masonite siding. The hardboard material itself, Masonite hardboard, is still sold as a generic product at lumber yards for craft, paneling, and underlayment. So if you mean Masonite doors, yes, they are still sold everywhere and are very common. If you mean Masonite siding, no, original Masonite branded lap siding is no longer sold, but similar hardboard siding is sold by other companies like LP SmartSide, which is engineered wood, not hardboard. The company Masonite is still in business and thriving in the door industry.
