What is Plasterboard?
Plasterboard is a panel of gypsum plaster pressed between a facer and a backer. It is also known as drywall, gypsum board, wallboard, or LAGYP. The term drywall is from the fact that walls made of drywall are installed without using water. The word gypsum is from the Latin word ‘gypsos’ which means ‘plaster.’ The plasterboard is used in the construction of interior walls and ceilings. It helps designers meet building regulations for acoustic insulation, thermal efficiency, and fire protection. In the mid-20th century, plasterboard construction was prevalent in North America as a time-saving alternative to the traditional lath and plaster.
History of Plasterboard
In 1888, the first plasterboard plant was opened in Rochester, Kent in the United Kingdom. Augustine Sackett and Fred Kane invented the Sackett Board in 1894. It was made by layering plaster within four plies of wool felt paper. Between 1910 and 1930, the Gypsum Board evolved. Paper-based facings replaced the inner felt paper layers. It later evolved to the layer of compressed gypsum between two sheets of heavy paper, as we know it today.
In the early years of its invention, it was thought to be a cheap fix since no fine art was involved in making plaster. Builders were, therefore, hesitant to use it. People were also generally wary of having their houses constructed with drywall since they considered it to be shoddy.
In 1910 United States Gypsum Corporation bought Sackett Plaster Board Company, and by 1917 came out with a product they called Sheetrock. People still did not change their perception of drywall. It is during World War II the United States appreciated drywall. The majority of the countries’ labour force was focused on war manufacturing.
As many soldiers went into war overseas, quick and inexpensive building materials were needed to offset the labour shortage. By the end of the war, the plasterboard was the dominant construction material in the United States. Plaster was replaced by plasterboard, leading to construction companies raking in high profits. The United States Gypsum Company is still one of the world’s top producers of plasterboard and related products to date.
Plasterboard in Australia and New Zealand
The leading constructor in the supply of plasterboard products is USG Australasia, which supplies popular worldwide brands such a Sheetrock. Another popular brand is Gyprock. Plasterboard is known by this term in Australia, while in New Zealand, it is known as Gibraltar board. Both countries use the metric system in the building. Panels are commonly sold in 1200 x 2400 mm, 1200 x 4800 mm, and 1200 x 6000 mm sheets.
Sound control using Plasterboard
Sound control can be in the form of sound insulation or sound absorption. Sound insulation blocks sound from traveling to adjacent spaces, while sound absorption prevents sound from bouncing around a room. Increasing the mass of walls and ceilings with plasterboard decreases sound energy. Multiple layers of plasterboard are recommended, rather than thick plasterboard. Sound transmission class (STC) ratings can be increased from 33 to 59 for a standard stud-wall. This is by using a double ½” drywall on both sides of a wood stud wall. It should have resilient channels on one side and fiberglass bat insulation between the studs.
