What is Sheetrock?

To clarify, 'Sheetrock' is a brand name, owned by the United States Gypsum company. They have an entire line of products with the 'Sheetrock' designation, such as 'gypsum panels', 'joint compound' and 'joint tape'.

In the last several decades, there have been several types and styles developed. Over the years, gypsum panels have replaced 'plaster' to provide smooth surfaces for walls and ceilings in many countries around the world.

The History of 'Sheetrock'

Lime based plaster has been around for thousands of years. Some of the famous architecture that we have admired down through the centuries employed various plastering techniques.

The problem with plaster is that when mixed and applied by hand, it is a fairly labor intensive activity. It also requires multiple coats to get the desired finish. Add to that the lengthy drying time that is often involved and you can see the need for a better product.

Toward the end of the nineteenth century, several manufacturers started using gypsum to replace lime based plaster. This material was cheaper and easier to deal with.

By the 1930's a paper faced sheet product had been developed that had a gypsum core. This was the forerunner of modern day gypsum panels that come in four foot wide sheets. Most homes in the united states have gypsum panel products fastened to the framing members to create a smooth wall surface. In fact, whether we realize it or not, very few people in this country can get through a day without seeing a wall or ceiling that has been covered by a gypsum panel product or 'sheetrock'.

The United States Gypsum Company has been and industry leader in gypsum based technology throughout the twentieth century and into this century.
