How to measure drywall thickness.
Drywall is an important part of the construction process. It provides a smooth, paintable interior surface for the walls and ceilings of most buildings across the country. Until you worked on your own drywall project, you probably never thought about the composition, quality, or thickness of drywall—but as you move ahead with renovating or refinishing a room, you’ll need to ponder certain key factors.
Discover how to determine the right ceiling drywall thickness for your home so you can keep your building up to code and avoid having to redo any work.
What is Drywall?
Drywall is known by many names, with plasterboard, sheetrock, or wallboard being some of the most common.
It’s made of gypsum, which is calcium sulfate dihydrate.
Sometimes, the manufacturer includes additives within the gypsum to improve durability or add other features, usually, qualities like mildew resistance, fire resistance, higher absorption capabilities, or greater plasticity.
The layer of gypsum is sandwiched between two sheets of paper—facer paper and backer paper.
