What is sheetrock? 

Sheetrock is the name of a brand that specializes in drywall. It’s a registered trademark of the US Gypsum Company. On the other hand, Drywall is the umbrella term used to determine Gypsum walls and ceilings. 

This is simply a summary about sheetrock drywall. There’s more you need to know. Spare a minute and give this a read. 

In this article, we’re going to discuss everything you need to know about sheetrock and drywall. 

Let’s begin!

What is Sheetrock? 

As we’ve mentioned before, Sheetrock is a brand specializing in drywall. They’re registered under the parent company US Gypsum. They were the first company to bring drywall to the market. 

Named as Sackett Board, USG launched the product first in 1916. After years of research and modification, we see the current product. 

Sheetrock is easily the most popular type of drywall in the US. Currently available in multiple styles and thicknesses, they’re a household name. 

How is Sheetrock Made? 

Sheetrock works just like any other sheetrock. The primary material in Sheetrock is Gypsum. The material is collected from mines and then refined as drywall. There’s a large amount of crystalized water in Gypsum, which is crucial for its stability. 

Once the Gypsum is mined, it’s taken to factories for refining. The raw Gypsum is converted to a paste and several additives are added. These include starch, paper pulp, and emulsifier. The materials are all blended to form a thick paste. 

Afterward, the paste is placed on top of a Manila paper. The general thickness of each sheet is ⅜ inch to ¾ inch. Then another sheet of Manila paper is put on top and sent to an oven and heated at up to 500 degrees. 

Once set, the material is cut into fine pieces and sent to the stores.

If you’re using any specialized drywall, it might have some extra additives. These include different types of chemicals and paper. You need to choose carefully. 

Types of Drywall 

There are many types of drywall for you to choose from. There are different types and each of them performs different functions. The categories can be divided into two types, thickness, and purpose.

Types of Drywall Based on Thickness

Based on thickness, there are three types of drywall. You have to choose them based on your needs. Generally, thicker walls are used in rooms that are more prominent. The types of drywall are- 

¼ Inch Drywall

The thinnest type of drywall available is the ¼” drywall. Since it’s the thinnest, it’s not a good idea for internal walls. It’s great for places like basements or garages. 

If you want to use this drywall, we recommend putting 1 4 cement boards with drywall for support. 

¾ Inch Drywall

In terms of thickness, this sits right in the middle. Generally, they’re never used as single walls. Rather used as support in other places. They’re mostly seen in bathrooms and other places where the wall needs extra support.

½ Inch Drywall 

The most common and sturdiest form of drywall. Since they’re the thickest, they’re also the strongest. They’re seen in almost every part of the house. From kitchens, bathrooms to bedrooms and living rooms. 

With that, we’ve discussed the types of drywall based on size. 

Types of Drywall Based on Function

There are many kinds of drywall based on function. You have to choose based on your needs. Otherwise, it’ll cause more harm than good.

To help you find the best one for you, here’s everything you need to know about them-

Moisture Resistant 

The first and most common type of drywall. They’re water resistant, thus they prevent any sort of water damage. Ideal for kitchens and bathrooms. 


If you’re looking for something light, this is right for you. This paper-backed drywall is very light and easy to set up. However, it’s still moisture and mold-resistant. 

In case you want to place drywall near shower, a greenboard is a useful and affordable alternative. 

Fire Resistant 

This type of drywall is generally only available in the ½” size. In this kind, the water in the Gypsum is crystallized. As a result, when the temperature gets too hot, the water starts to melt. 

Eventually, the water turns to vapor, keeping the drywall cool. This is recommended in kitchens and workshops. Especially where fires are prevalent.

Ceiling Drywall

Drywall like this is ideal for household ceilings. They are made to hold off more water than normal drywall. As a result, they prevent sagging and leaking from the roof.

This is ideal if you have pipes running from your roof. They’re on the expensive side, so keep that in mind. 

Acoustic Drywall

If you want sound-proofing, this is the way to go! The name Acoustic comes from its ability to hold off sound. The high-density Gypsum in it is also great for holding off moisture. 

How To Set Up Drywall?

Setting up drywall is as easy as it gets. With a bit of effort, you can easily set it up without any help. Follow these steps carefully and you’re good to go.

With that said, the steps to setting up drywall are-

Step 1 of 3: Check the Area 

The installation area of your house before starting. Make sure there are no holes or spots in the walls. If you need any repairs, get them done immediately. Also, make sure your drywall doesn’t touch ductwork.

Step 2 of 3: Measure and Cut Your Drywall 

The first step is to measure the drywall carefully. Generally, drywalls are available in 4*8’ slabs. Take a measuring tape and measure the space you want to place the drywall. Make sure the drywall ends at the joists with no free space.

Take a saw and cut accordingly. Try to be as precise as you can. Use a good saw to prevent any blunt edges or missed spots.
