In use as early as 1900, rock lath (also known as “button board,” “plaster board” or “gypsum-board lath”), is a type of gypsum wall board (essentially an early form of drywall) with holes spaced regularly to provide a ‘key’ for wet plaster.
What were walls made out of before drywall?
Before drywall became widely used, building interiors were made of plaster. For hundreds of years, walls and ceilings have been constructed by placing layers of wet plaster over thousands of wooden strips called laths.
What did old houses use instead of drywall?
Older homes and high-end new homes will have plaster instead of drywall. Harder and more durable, plaster is also more expensive to install. In old homes, plaster is a three-coat system applied over wood or metal lath. In new homes, it’s usually a single coat applied over blueboard, a special type of drywall.
What were walls made of in 1950?
Gypsum Walls According to the Gypsum Association, half of the homes built during the 50s had walls made from lightweight gypsum lath and plaster, while the other half had a gypsum wallboard construction. Gypsum products produced smooth-textured walls.
What were old walls made of?
Two of the most common forms of interior wall materials are plaster and drywall. Plaster has been used since ancient times. The earliest plaster was usually made of lime, sand, animal hair and water [source: MacDonald].
What did they use before plasterboard?
The lath and plaster technique was generally used to finish interior walls and ceilings from the 1700s to the early-to-mid 1900s before it was superseded by modern gypsum plaster and plasterboard. Wood lath is typically about one inch (2.5 cm) wide by four feet (1.22 meters) long by 1⁄4 inch (6.4 mm) thick.
When did they start using drywall?
Drywall was invented in 1916. The United States Gypsum Corporation, a company that vertically integrated 30 different gypsum and plaster manufacturing companies 14 years prior, created it to protect homes from urban fires, and marketed it as the poor man’s answer to plaster walls.
When did homes switch from plaster to drywall?
The lath and plaster model was popular in the United States and Canada through the 1950s; however, this was replaced with drywall and plasterboard by the 1950s. This modern material worked better with wiring practices, as electricity became standard in most homes and offices.
Did they use drywall in the 60s?
By the late 1950’s and 1960’s, though plaster was still found in new construction, drywall was beginning to be used at an increasing rate.
What is metal lath used for?

What were walls made of in 1900?
Until about 1900, all plaster walls and ceilings were done with lime-based plaster applied over wooden lath. The lime plaster was a mixture of lime, water and sand with animal hair used as a binder.
Why is there OSB behind drywall?
As previously stated by others, drywall has zero structural resistance to loads; therefore, another material (OSB or dimensional lumber) must be secured to the wooden or metal studs forming the wall. Once in place, any anchor used for the fixture will now bite into a more structurally sound material.
Why did old houses have spaces between walls?
They’re there to provide a divisions in rooms and for things like electrical cables to run through. Load bearing walls tend to be a little chunkier and are made from brick or cinderblocks and are designed to hold-up the structure of the home.

From the 1700s all the way through the 1940s, lath and plaster was the interior wall construction method of choice. Builders nailed thin, closely spaced strips of wood (lath) to wall studs and then smoothed multiple coatings of plaster over the lath to form flat wall surfaces.
What were walls made of in 1960s?

When did horse hair stop being used in plaster?
Horsehair plaster, also known as lath and plaster, is typically found in older homes and homes of significant historical value. This practice is not commonly used today. In fact, drywall began replacing the process in the 1950s. However, you can still find a lot of homes with horsehair plaster.
When was plasterboard first used?
Drywall, also known as plasterboard or wallboard was invented in 1916 by a company based in America known as The U.S Gypsum. Initially it was sold as small tiles for fireproofing specific areas but within a few years it took shape to what exists today.
What is drywall called in Australia?
Most often called plasterboard in Australia, drywall is one of the world’s most common building materials.
Why is lime plaster no longer commonly used?
The promotion of modern gypsum-based plasters has led to the almost complete demise of lime plastering, and of many of the traditional skills associated with the craft. This has been exacerbated by the plastering trade being divided into flat and decorative work, with new ‘fibrous plasterwork’ being made in workshops.
