Product Description
Product Description
12.5mm Standard Plasterboard Wallboard is the standard thickness specified for internal walls, partitions and ceilings across indoor applications in the UK. This tapered edge version is built for taping and jointing: the recessed long edges let you fill and tape the joints flush, for a smooth, seamless finish that is ready to paint without skimming the whole surface.
Each board measures 2400mm x 1200mm and covers 2.88m², a full standard sheet that lines up with 400mm and 600mm stud and joist centres and covers ground quickly. It is built around a non-combustible gypsum core bonded to an ivory paper face, which offers inherent fire resistance and takes a skim plaster finish or direct decoration once the joints are taped and filled. It fixes by screw to timber or metal stud frames, or by dot and dab adhesive directly to masonry, blockwork or brick.
The tapered edge is what sets this board apart from a square edge. Where two tapered boards meet, the shallow recess gives room for scrim tape and jointing compound to sit flush with the board face, so the finished joint disappears rather than standing proud. That makes it the board for a tape-and-joint, drywall-style finish taken straight to paint, though it will also take a plaster skim over the whole face if that is your preferred finish.
12.5mm tapered edge plasterboard suits the majority of standard wall and ceiling work in new build and refurbishment, and should be installed in line with the manufacturer's guidance and your project specification.
Where to use 12.5mm tapered edge plasterboard:
- Stud partition walls: fixed to timber or metal stud frames in new build and refurbishment projects.
- Wall linings: dot and dab adhesive fixing to masonry, blockwork or brick.
- Ceiling linings: screw fixed to timber joists or metal ceiling grids.
- Room dividers and internal partitions: quick and cost-effective compared to blockwork.
Key Benefits of 12.5mm Tapered Edge Plasterboard:
- 12.5mm gypsum plasterboard, the standard thickness for internal walls, partitions and ceilings.
- Tapered long edges designed for taping and jointing to a flush, seamless finish.
- Ivory paper face ready for a skim plaster finish, paint or a textured finish.
- Non-combustible gypsum core offering inherent fire resistance.
- 2400mm x 1200mm full sheet covering 2.88m², sized to suit 400mm and 600mm stud and joist centres.
- Screw-fixes to timber or metal stud frames, or bonds to masonry, blockwork or brick by dot and dab.
- Suited to stud partitions, wall linings, ceiling linings and internal room dividers.
- Compatible with single or multi-layer build-ups in new build and refurbishment.
- Insulation UK own-brand board at competitive trade pricing, with bulk pricing available.
Good to know:
- Tapered on the long edges only. The recess runs down the two long sides; cut ends and board ends butt together, so tape and fill those joints as you would any butt joint.
- Made for tape and joint. For a flush, paint-ready finish, scrim tape and fill the recessed joints; skim the whole face instead if you prefer a plastered finish.
- Not moisture resistant. For bathrooms, wet rooms or damp, unheated spaces, use a moisture-resistant board.
- Not a rated fire board. Where a specified fire performance is required, use a fire-resistant board within a tested wall or ceiling system.
- Store flat and dry. Keep boards flat, off the ground and out of the damp before fixing, and lift with two people.
For a flush, paint-ready finish across the bulk of a job's walls and ceilings, 12.5mm tapered edge plasterboard is the standard board to reach for first: quick to fix, easy to joint and ready for whatever decoration follows. If you need enhanced fire performance, acoustic insulation or moisture resistance, see our specialist plasterboard range, including acoustic plasterboard and fire-rated boards.
