Before you tackle any drywall project or hire a contractor, knowing what drywall is made of and how the material works will help your project go more smoothly. In this blog post, we will discuss the main components of drywall and why these components are used in construction.


What is Drywall?

Drywall, also known as gypsum board or sheetrock, is a wall covering made of gypsum plaster pressed between two thick sheets of paper. It typically covers interior walls and ceilings in residential homes and commercial buildings.


The Gypsum Plaster Core

The drywall core is a white powdery substance made up mostly of gypsum (calcium sulfate dihydrate), mined from natural deposits since ancient times. The gypsum plaster is mixed with water to create a paste pressed into molds between two thick pieces of paper. The paste dries and creates a solid bond that will keep the panel from crumbling if it gets wet or damaged during installation.


The Paper Covering

The paper covering outside each drywall panel serves several vital functions. It helps protect the core from damage during transport, provides extra strength for installation, and acts as a sound barrier. The paper also provides an optimal surface for finishing materials like paint or wallpaper to adhere to once the drywall is installed.  The most common type of paper used on drywall panels is kraft paper, primarily recycled fibers, and waxes that provide added weather resistance and durability.


Now that you know what drywall is made of, it’s easier to understand why it’s an essential part of many construction projects. It provides your home with much-needed structural support. It provides insulation against sound transmissions and an ideal surface for finishing materials like paint or wallpaper. Whether you plan on doing the work yourself or hiring professionals, understanding what goes into making drywall can help you make more informed decisions when working on any home improvement project involving walls and ceilings.
