Drywall, also known as gypsum board or sheetrock, is made from a naturally occurring mineral called gypsum. The process is more advanced than many homeowners realize:

•             Gypsum is mined from the earth or reclaimed from industrial by‑products.

•             It’s crushed into a fine powder and heated to remove moisture.

•             Water and additives are mixed back in to create a smooth, workable slurry.

•             This slurry is sandwiched between two layers of heavy paper — one forms the face of the board, the other the back.

•             The continuous sheet moves down a production line where it hardens, dries, and is cut into standard panels.

•             Once cured, the boards are stacked, bundled, and shipped to job sites.

The result is a strong, fire‑resistant, easy‑to‑finish panel that forms the backbone of modern interior walls and ceilings.

A Short History of Drywall

Drywall is a relatively new invention in the long history of building materials.

•             Before drywall, walls were built using lath and plaster, a labor‑intensive process that required multiple coats and long drying times.

•             In 1916, the U.S. Gypsum Company introduced the first version of modern drywall, originally called Sackett Board.

•             At first, builders resisted it because plaster was considered the “proper” way to finish walls.

•             During World War II, drywall became popular because it was faster and cheaper, allowing homes and buildings to be constructed quickly for returning soldiers and growing families.

•             By the 1950s and 60s, drywall had become the standard for residential and commercial construction.

•             Today, it’s valued for its fire resistance, affordability, speed of installation, and clean finish.

Why This Matters to Homeowners

Understanding the material helps clients appreciate the craftsmanship behind a professional drywall job. Drywall may look simple, but the quality of the installation — straight lines, smooth seams, proper taping, and clean finishing — makes a huge difference in the final appearance of a home.
