Welcome to our comprehensive guide on plasterboard! Whether you're embarking on a DIY project or working on a professional renovation, this FAQ aims to answer your most pressing questions about different types of plasterboard.


What is Plasterboard?

Plasterboard, also known as drywall or gypsum board, is a building material used for walls and ceilings. It's made of a layer of gypsum sandwiched between two sheets of thick paper. Plasterboard is widely used due to its versatility, ease of installation, and smooth finish.


What are the Different Types of Plasterboard?

There are several types of plasterboard, each designed for specific applications and environments. Here’s a breakdown of the most common types:


Acoustic Plasterboard

Acoustic plasterboard is designed to reduce noise transmission between rooms. It’s ideal for creating quiet spaces in homes, offices, and multi-family buildings. This type of plasterboard contains sound-insulating materials that help dampen noise.

Fire Resistant Plasterboard

Fire resistant plasterboard has a core enhanced with glass fiber and other fire-resistant materials. It’s used in areas where fire protection is crucial, such as in garages, kitchens, and between shared walls in multi-family housing.

Moisture Resistant Plasterboard

Moisture resistant plasterboard is treated with water-repellent additives and is perfect for areas with high humidity, like bathrooms, kitchens, and utility rooms. It helps prevent mold growth and water damage.

Tapered Edge Plasterboard

Tapered edge plasterboard features tapered edges along its length, making it easier to achieve a smooth finish when jointing. It’s ideal for walls and ceilings where a seamless look is desired.

Square Edge Plasterboard

Square edge plasterboard has straight edges and is typically used for ceilings or where the joints won’t be visible, like under wallpaper.

Vapour Plasterboard

Vapour plasterboard incorporates a vapor barrier to control moisture levels within walls, helping to prevent condensation and related issues.

Insulated Plasterboard

Insulated plasterboard has an additional layer of insulation, providing enhanced thermal performance. It’s used in spaces where maintaining temperature control is essential.


Common Questions about Plasterboard


How Many Sheets of Plasterboard on a Pallet?

The number of sheets per pallet varies by manufacturer and sheet size, but typically, a pallet can hold about 40 to 60 sheets of standard plasterboard.

How Thick is Plasterboard?

Plasterboard thickness varies, with common sizes being 9.5mm, 12.5mm, and 15mm. The choice depends on the application, with thicker boards offering better sound and fire resistance.

How Difficult is it to Install Plasterboard?

Installing plasterboard is relatively straightforward for those with basic DIY skills. The process involves:

  • Measuring and cutting the boards.

  • Fixing them to studs or joists.

  • Finishing with joint tape and plaster.

Should You Remove the Battens?

If you’re replacing old plasterboard, it’s best to inspect the battens. If they are in good condition, you can reuse them. However, if they show signs of damage or rot, they should be replaced.

When Should You Use Hard Plaster Instead?

Hard plaster is recommended for areas exposed to high wear and tear or moisture, such as hallways, kitchens, and bathrooms. It provides a more durable and moisture-resistant surface than plasterboard alone.

How to Secure Heavy Loads to Plasterboard?

To secure heavy loads like shelves or TVs:

  • Use wall anchors or toggle bolts specifically designed for plasterboard.

  • For very heavy items, it's best to mount them into the studs behind the plasterboard.

How Strong is Plasterboard?

While plasterboard is strong enough for regular wall construction, it’s not designed to bear heavy loads without support. Reinforcements or special fixings are necessary for heavy items.

Which Equipment Do You Need?

Basic equipment for installing plasterboard includes:

  • Utility knife

  • Tape measure

  • Straight edge

  • Drill or screwdriver

  • Plasterboard screws

  • Joint tape and plaster

Additional tools such as a spirit level and stud finder can also be very helpful.


How to Remove Plasterboard

To remove plasterboard:

  • Score along the seams with a utility knife.
  • Use a pry bar to gently pull the panels away from the studs.

Always wear protective gear to guard against dust and debris.
