History

• Although hardboard was invented in the late 19th century, William H. Mason invented Masonite in 1924. Mason, a researcher, engineer and inventor, began manufacturing the sheets approximately four years later. By the 1940s, Masonite sheets were used as building materials as well as ramps, cabinets, appliances and artistic media. According to Panel Processing, over 28 businesses manufacture products similar to the hardboard sheets invented by Mason. However, Masonite sheets are only manufactured by the Masonite Corporation which as registered a trademark of the Masonite name.

Variations and Uses

• Generally, these sheets are sold in thickness from 1/8 to 1/4 inch. Masonite sheets can also be used for projects that not related to home building. For instance, theaters use these sheets to construct stages. Also, movers can use sheets to move furniture. Movers place the sheets on the floors and against walls so they can easily move furniture without damaging the houses or offices.
  
  

Types

• Originally, Masonite sheets were made by creating long fibers from wood chips, then steaming them into boards. The wet process creates finished sheets with one smooth side and a rough side. The wet-dry process creates Masonite sheets that have two smooth sides.
