Masonite and other hardboards are engineered woods created from highly compressed wood fibers. Masonite is commonly used in construction because it is cheap, easy to work with, and relatively strong.

What happens if you put masonite on siding?
Many installers would not use the correct install procedure and nail the bottom of the siding to the board below. This caused issues with water seeping in, causing blistering around the nails and rot damage. Masonite absorbs water, which causes it to expand, resulting in swelling and blistering on the boards. Repeated wetting and drying can also cause it to warp and buckle over time. It can soften and even rot away over time in humid conditions, and dampness can lead to infestations of mildew or even toxic mold. Speaking of infestations, Masonite is susceptible to damage from termites or other insects.

History
A product resembling masonite (hardboard) was first made in England in 1898 by hot-pressing waste paper. Masonite was patented in 1924 in Laurel, Mississippi, by William H. Mason, who was a friend and protégé of Thomas Edison. Mass production started in 1929. In the 1930s and 1940s, Masonite was used for applications including doors, roofing, walls, desktops, and canoes. It was sometimes used for house siding.
Production

Forming the fibers into boards on a screen, the boards are then pressed and heated to form the finished product with a smooth burnished finish. (Later a dry process wit…
Deterioration
Masonite swells and rots over time when exposed to the elements, and may prematurely deteriorate when it is used as exterior siding.
