WHAT IS GWB OR DRYWALL?
Gypsum wall boards are pressed gypsum panels between thick paper. These panels are also known as Sheetrock, but Sheetrock is the brand of a company that produces panels and is a registered trademark in the United States of America.
The panels come in the following sizes, which are the most common.
- 1 inch are the most used for fire resistant enclosures. This panel consists of a fire resistant gypsum core that is covered on one side 100% moisture resistant, which is green color and is the front side of the panel.
- 5/8 of an inch is used to cover residential ceilings and is one hour fire resistant.
- 1/2 inch is used to cover walls, either metal or wood in residential or commercial projects and is the most common in the world.
- 1/4 ‘inch is a good option for curved walls and arches, but double boards must be used to obtain the thickness of 1/2 inch.
Installing gypsum panels must be done with the idea of creating as fewer joints as possible.
This means that it is advisable to work with the largest panels.
RISK FOR THE INSTALLERS WHILE DRYWALL INSTALLATION:
- Drywall Installers are at risk of falling, back injuries, dust respiratory exposure, sprains of backs, shoulders, and arms
- The weight range of drywall is between 60 and 125 pounds, depending on the size of the sheet. So handle these boards with care during the transportation and installation.
