What is plasterboard?

Plasterboard, also known as drywall, is a piece of Gyproc, or gypsum, that is sandwiched between thick, heavy-duty construction paper. Plasterboard is most commonly used on walls and ceilings and is then finished off with plaster or paint.

What types of plasterboard are there?

There are a number of different types of plasterboard available, including foam backed plasterboard. The type you want will depend on where it is being installed and why.

Square edge plasterboard

Firstly, plasterboard can have different edges, depending on how the wall is being finished. Opt for square-edged plasterboard if you’re going to plaster the surface after installation to create a smooth, flat finish – this is what you’ll need if you’re planning on painting or wallpapering the room. This type of finish can result in a glossy finished product, but occasionally issues will occur with cracks as the plaster dries out, and you will need to plan in extra time to allow the plaster to dry out before progressing.

Tapered edge plasterboard

Alternatively, opt for tapered edge plasterboard. Tapered edge plasterboard is the plasterboard required if the surface is going to be dry-lined, which is a seemingly quicker and easier alternative to using wet plaster. Tapered edge plasterboard has thinner edges than central sections, meaning that scrim and joint fillers can be applied where two edges meet, whilst still ensuring the surface is smooth and even to be painted over. 

Moisture resistant plasterboard

Moisture resistant plasterboard has been developed to be used in humid and damp environments such as kitchen and bathroom ceilings and walls. Moisture resistant additives have been added to the core composition to prevent moisture from being absorbed, and moisture resistant plasterboard products are green in colour to provide easy and quick recognition. 

It isn’t recommended to plaster over moisture-resistant plasterboard, as wet plaster attracts and soaks up moisture. However, there is a range of alternatives including a waterproof tanking system. 

Acoustic plasterboard

Acoustic plasterboard not only provides a quick and easy way to finish a room, but it also reduces the level of noise that travels both into the room and out of the room. This can create a more private and quiet environment, particularly useful in studies, bedrooms and living rooms, as well as internal partition walls. For best results, combine acoustic plasterboard with a number of other acoustic insulating products. 

Fire-resistant plasterboard

Fire-resistant plasterboard provides protection against fire and comes in a wide range of sizes, thicknesses and fire ratings. Choose from fire-resistant plasterboard that is non-combustible, due to the addition of glass fibre and other additives, or alternatively opt for fire-resistant plasterboard that resists fire for 240 minutes before combusting. It is important to ensure you have the correct rated fire resistant board, particularly if it is specified in building regulations.

Insulated plasterboard

Insulated plasterboard is a great time-saver and offers you extra assurance that your insulation is going to stay in place. Thermal insulation board is bonded to the back of the plasterboard which helps give a swift installation. It can also be a cost-effective solution to insulating your walls as the insulated plasterboard may be cheaper than buying both constituent parts. Our insulated plasterboard range comes from well-known brands Celotex and Kingspan so you're free to take your pick between whichever suits you. Both the Celotex and Kingspan insulated plasterboard offerings come in many sizes and thicknesses for application in between and under rafters and joists, in solid masonry walls and in timber frame builds.

How to cut plasterboard

Often, plasterboard sheets come in larger sizes than are required for the project in hand. Because plasterboard can be used in so many different ways, both in DIY projects and larger-scale situations, it will often need to be cut to a specific size, but how do you cut plasterboard?

How to cut a straight line in plasterboard

  1. Measure the cut you need to make by working out where you need the line and drawing a rough guide with a pencil
  2. Hold a spirit level over the pencil marking on the plasterboard and push it down firmly so it stays in place
  3. Use this straight line to cut a shallow mark into the plasterboard with a Stanley knife or something similar
  4. Use this a guideline and cut the plasterboard all the way through with a saw
  5. Check the progress of the cut regularly to ensure it’s staying where you’ve marked out.

  7. Measure the cut you need to make as accurately as you can
  8. Mark out the cut with a pencil
  9. Use a plasterboard hammer to bang 50mm inside one of the cut lines (this line will let you insert the blade of the saw to begin the cut so it’s a crucial step)
  10. Insert the saw into the 50mm deep line and begin cutting
  11. Check the progress of the cut regularly to ensure it’s staying where you’ve marked out.

How to install insulated plasterboard

Insulated plasterboard is incredibly popular due to the reduction in labour and construction times, but how do you install insulated plasterboard? We’d recommend using the direct bonding method of fixing insulated plasterboard to ensure the insulated plasterboard is installed correctly as well as quickly. 

Direct bond installation of insulated plasterboard

  1. Mark spots on masonry and ceiling to establish the new wall plane
  2. Make 1200mm marks vertically on the wall to indicate the position of the boards
  3. Start installing from an internal corner or from a window or door reveal
  4. Make a continuous bed of adhesive around the perimeter of the wall and around services/openings to take into account building airtightness
  5. Cut the board approximately 15mm short of the floor to ceiling height and position it with the bottom edge resting against packing strips
  6. Apply a dab of adhesive to the wall (each dab of adhesive should be around 750mm x 250mm, covering 20% of the board area)
  7. Tap the boards into position with a straight edge and check the alignments with the markings made earlier
  8. Lift the boards to the ceiling edge and support them until the adhesive has set
  9. Nail in fixings at the mid-point of the board around 25mm from the edge
  10. Butt all other boards closely together and fix these using the same technique

Can you dot and dab insulated plasterboard? Although not our primary recommended method of installing insulated plasterboard, dot and dab is another method of fixing insulated plasterboard. Take a look at our guide on installing plasterboard where this method is featured for more information.
