12.5mm Plasterboard Non combustible
12.5mm plasterboard is a standard type of gypsum sheet used to line ceilings and internal walls. At this thickness, 12.5 millimetre panels offer a good balance of rigidity and lightness. They are easy to handle on site but stiff enough to remain flat, making them the go-to choice for most general lining jobs.
What is plasterboard 12.5mm?
Plasterboard 12.5mm is a gypsum-core panel faced with paper and manufactured to a thickness of 12.5 millimetres. That thickness is a common industry size because it works well for single-layer linings, partitions, and ceilings.
It is fixed directly to studs, ceilings, or battens, and also works well with plasterboard adhesive in dot and dab fixing methods.
The panel comes in various performance types that meet most general building needs. Some of the most common types available include acoustic plasterboard 12.5mm panels, 12.5mm tapered edge plasterboard sheets, and 12.5mm FireLine plasterboard.
What is 12.5 plasterboard used for?
12.5mm plasterboard panels are commonly used for interior wall linings, ceilings, partitions, and many retrofit tasks.
Depending on the variant chosen —standard, fire-resistant, acoustic, or moisture-resistant —the same 12.5mm board can be used to boost fire protection, minimise sound transfer, or provide extra moisture resistance in bathrooms and kitchen spaces.
It is easily fitted on both solid masonry and metal or timber frames.
Types of 12.5mm plasterboards
At Insulation Wholesale, you’ll find 12.5mm plasterboards for varying job requirements:
Standard 12.5mm plasterboard
A general-purpose lining board for everyday walls and ceilings.
It is lightweight and easy to resize, making it perfect where extra fire, acoustic, or moisture performance is not necessary.
Fire plasterboard 12.5mm (12.5mm FireLine)
Features a gypsum core reinforced with glass fibre and other additives to provide extended fire resistance. It is added to improve fire protection around stairwells, garages, some escape routes, or where a specification calls for a fire-rated partition.
FireLine boards are tested to building standards and are sold in sizes that match typical ceiling and wall systems.
Acoustic plasterboard 12.5mm (soundboard)
These are manufactured to reduce sound passing through walls and ceilings. They’re denser or specially engineered, so a single layer improves privacy and reduces airborne noise.
They are a good choice for separating bedrooms, home offices, and flats, or any room where quieter conditions are needed.
For stronger acoustic performance, use with acoustic systems combining insulation and double plasterboard layers.
12.5mm Tapered edge plasterboard
Tapered edges make jointing quicker and neater. The slight bevel creates a groove for tape and joint compound that can be feathered out to an invisible seam.
Use tapered edge boards to tape and joint rather than skim. They save finishing time and give a clean, painted finish.
Moisture-resistant / Foil backed plasterboard
Moisture-resistant 12.5mm boards (sometimes called “moisture panel”) have treated cores and paper to resist brief exposure to humidity.
Foil-backed options add a metallised foil layer that acts as a vapour control layer and can help limit interstitial condensation in cold/warm junctions.
They are useful in garages, utility rooms, and areas where extra vapour control is desired, but not suitable for continuously wet areas like showers without a suitable tanking system.
Other specialist 12.5mm boards
There are also insulated or foil-faced 12.5mm products, as well as specialist performance boards designed for specific ceiling or wall systems. Select these to match the wall or ceiling build-up and the required performance, whether thermal, acoustic, or fire.
Benefits of 12.5mm plasterboards
Installing 12.5 boards offers these benefits:
- Versatile – For ceilings, walls, partitions, and lining systems.
- Balanced strength and weight – They are stiff enough for single-layer use, but still easy to lift.
- Clean finish – They accept tape & jointing well.
- Performance options – Choose FireLine, acoustic, moisture-resistant, or foil-backed to suit the room.
- Speed on site – Common size that is easy to source and works with standard fixings and compounds.

FAQ
Where to buy 12.5mm plasterboard?
Buy 12.5mm plasterboard online directly from Insulation Wholesale. We stock pallet and single-sheet options and can advise on which board is best suited to a particular wall or ceiling. Plus, we make fast UK delivery on all bulk orders.
How many 12.5mm plasterboard on a pallet?
Pallet counts vary by producer and sheet size. Most 2400 x 1200mm and 2440 x 1220mm board pallets hold 42, 60, 64, or 72 sheets.
Quantities can also vary based on whether the panels are tapered-edge or heavier performance models. It is best to confirm the exact pallet count on the product page before ordering.
How to cut 12.5mm plasterboard?
- Mark the cut with a straightedge.
- Score the face paper firmly with a utility knife.
- Snap the board along the score.
- Fold back, then trim the backing paper.
Support the board to avoid breakage when making long cuts. Always wear protective gear, especially when cutting indoors.
How much adhesive for 12.5mm plasterboard?
Coverage depends on the adhesive type and the dot-and-dab pattern. But a 25kg bag typically covers 4.2–4.6 m² when dot-and-dabbed.
How to fit 12.5mm plasterboard?
Secure with drywall screws for timber or metal framing, and follow the manufacturer's guidance for ceilings. Use screws spaced roughly 230mm apart across the board field (or 300mm on walls). Use 150mm spacing at board ends for secure fixing.
For masonry, dot-and-dab a suitable adhesive product or use mechanical fixings.
Once securely fitted, tape the joints, apply joint compound, then sand. You can now paint or apply a skim coat to get a plaster finish.
