You’ve probably heard people say ‘drywall’ and ‘plasterboard’ like they’re the exact same thing. And truthfully, in a lot of situations, they are. But then someone else tells you they’re different, or that the terms only apply in certain places. Suddenly, it feels confusing. Are you using the right word? Does it even matter?
Drywall vs. Plasterboard: Are They Just Different Words?
This is where it gets a bit mixed. The short answer? They refer to the same basic product, but the terms are used differently depending on where you are or who you’re talking to.
Both drywall and plasterboard are types of building boards made from a layer of gypsum sandwiched between sheets of paper. They’re used to make interior walls and ceilings, usually as a faster and easier alternative to traditional wet plaster. If you’re doing some renovation or building, this is the stuff that forms the surface you eventually paint, wallpaper, or tile.
Now, here’s the twist. In the UK, ‘plasterboard’ is the term you’ll hear most often. In North America, it’s more commonly called ‘drywall.’ But the product itself? Pretty much the same thing.
So why two names? Well, part of it is just regional language. Kind of like how ‘boot’ and ‘trunk’ mean the same thing, depending on which side of the Atlantic you’re on.
But there’s more to it than just wording.
Are There Any Real Differences?
Technically speaking, no. At least not when you’re just talking about the standard board used for walls and ceilings. Both drywall and plasterboard are manufactured in sheets and come in various thicknesses, lengths, and types.
However, if someone’s using the word ‘drywall’ in a broader sense, they might be referring to the whole process of installing and finishing those boards. In that case, ‘drywall’ isn’t just the board itself. It also includes the taping, mudding, sanding, and preparing the surface. Some people even include painting in that conversation.
‘Plasterboard,’ on the other hand, tends to refer more strictly to the board product itself.
But these are minor semantic differences. For most practical purposes, if someone gives you drywall or plasterboard, you’re getting the same thing.
Why the Term ‘Drywall’ Exists
You might be wondering, why not just stick to one term if the product is the same?
The term ‘drywall’ came about as a way to distinguish it from traditional wet plastering. With wet plaster, you’re applying a paste to the wall, which then has to dry slowly. It takes skill and time. Drywall, or plasterboard, skips that part. You screw the board to the frame, fill the joints, sand it, and you’re pretty much done.
So ‘drywall’ was a way of saying, ‘Look, this stuff doesn’t need all that drying time. You just fix it in place, finish it, and move on.’
Different Types of Plasterboard (or Drywall)
While the basic board is the same, manufacturers have developed different versions depending on what you need. Some are fire-resistant, some resist moisture, and some are extra tough for impact-prone areas.
For example:
-
Standard plasterboard. The go-to for regular walls and ceilings in dry areas.
-
Moisture-resistant board. Often green in colour, used in bathrooms or kitchens.
-
Fire-resistant board. Contains extra additives to improve performance during a fire.
-
Acoustic plasterboard. Thicker and denser, designed to reduce sound transmission.
-
Impact-resistant board. Made tougher for areas like schools or hospitals.
These types are available under both the ‘drywall’ and ‘plasterboard’ labels. So again, the naming doesn’t change the product. It’s just how people refer to it.
What About Gypsum Board?
Here’s another term you might have come across. ‘Gypsum board.’ Now we’re in manufacturer or technical territory. Gypsum board is the formal term for any board with a gypsum core. Both drywall and plasterboard fall under this umbrella.
It’s a bit like saying all smartphones are phones, but not all phones are smartphones. Gypsum board is the category, and plasterboard or drywall are the products within that category.
So, Which Term Should You Use?
If you’re in the UK, most builders, DIY stores, and tradespeople will call it plasterboard. Use that term and you’ll be understood clearly.
If you’re talking to someone in North America, ‘drywall’ is what they’re likely to use. Say ‘plasterboard’ over there and someone might still get what you mean, but they might give you a confused look at first.
If you’re writing something or working on a project with international input, it can help to mention both terms the first time. ‘We’ll be using standard plasterboard (also known as drywall)…’ That way, nobody gets lost.
Installing It: Is It All the Same?
Yep, the installation process is the same regardless of what you call it. The boards are cut to size, screwed into timber or metal studs, then the joints are taped and filled.
After that, you sand the joints smooth and the wall is ready for decorating.
Most boards are easy to cut with a utility knife, though thicker or specialist boards might need a saw. You don’t need special tools or training, but a steady hand and a bit of patience certainly help.
