SPK 12.5mm SB Plasterboard + 10kg MLV 1200mm x 1200mm
Higher-Mass Acoustic Plasterboard with Bonded 10kg Barrier
The SPK 12.5mm SB Plasterboard + 10kg Barrier is the heavier-duty option in the SPK acoustic board range. It is designed for soundproofing projects where added mass is required but where you still want a relatively slim board build-up.
This board combines a 12.5mm SB plasterboard layer with a bonded 10kg acoustic barrier, giving a total board thickness of 17mm. The result is a practical composite soundproofing board that can be used in wall and ceiling systems to help reduce airborne sound transfer.
The bonded barrier layer removes the need to separately cut and bond loose MLV to plasterboard on site. This saves installation time and gives a cleaner, more consistent board-and-barrier product.
What This Board Helps With
This product is designed to help reduce airborne noise, including:
- Voices from neighbouring rooms or adjoining properties
- TV noise and general household sound
- Music and media noise
- Office conversation noise
- Noise transfer through lightweight stud walls
- Airborne noise passing through existing wall and ceiling structures
- Sound transfer in bedrooms, flats, studios and home offices
For best results, this board should be used as part of a complete soundproofing system. Acoustic performance depends on the existing structure, installation quality, sealing, board fixing method, flanking paths and the full build-up used.
Key Benefits
Heavier 10kg Barrier Layer
The bonded 10kg barrier adds more mass than the 5kg version, making this the stronger choice where higher airborne noise reduction is required.
Slim 17mm Total Thickness
At 17mm total thickness, this board gives a higher-mass acoustic upgrade while keeping the system slimmer than many 27mm to 30mm composite soundproofing boards on the market.
Plasterboard and Barrier in One Board
The acoustic barrier is already bonded to the plasterboard, reducing the need for separate membrane installation. This can save time, reduce mess and make fitting more straightforward.
Designed for Walls and Ceilings
Use this board for party walls, internal walls, stud walls, ceiling linings and refurbishment projects where extra acoustic mass is needed.
Good Upgrade from the 5kg Version
Choose this 10kg version where you want a heavier board and better mass loading than the 5kg barrier option, while still keeping the installation relatively simple.

Recommended Applications
Party Wall Soundproofing
Use on separating walls where everyday airborne noise is the main issue, such as voices, TV noise and general neighbour noise.
Stud Wall Upgrades
Use on timber or metal stud walls as part of a full soundproofing build-up. For improved results, combine with acoustic mineral wool inside the cavity and seal all perimeters correctly.
Ceiling Soundproofing
Use as a high-mass ceiling board where additional density is required. For better ceiling performance, it can be combined with acoustic mineral wool, resilient bars, acoustic clips or other decoupling methods depending on the structure.
Studios and Media Rooms
Suitable for rooms where improved acoustic separation is needed, including home studios, music rooms, cinema rooms and media spaces.
Flats and Refurbishment Projects
A strong option where you need better acoustic mass but cannot afford to lose excessive floor area or ceiling height.
5kg vs 10kg Barrier Board
| Option | Best for | Thickness |
|---|---|---|
| SPK 12.5mm SB Plasterboard + 5kg Barrier | Standard acoustic upgrades where a slimmer, lighter board is preferred | 15mm |
| SPK 12.5mm SB Plasterboard + 10kg Barrier | Higher-mass upgrades where stronger airborne noise reduction is required | 17mm |
The 5kg version is the lighter, slimmer option. The 10kg version is the heavier, higher-mass option for more demanding wall and ceiling soundproofing projects.
Installation Guidance
Measure the area carefully and allow for cuts, wastage and board handling. Boards should be fixed securely to a suitable wall or ceiling structure using appropriate plasterboard fixings.
For best acoustic performance:
- Stagger board joints where possible.
- Seal all perimeter gaps with acoustic sealant.
- Avoid leaving open gaps around sockets, pipes or service penetrations.
- Use acoustic socket boxes or putty pads where sockets are present.
- Do not bridge resilient bar or acoustic clip systems with incorrect fixings.
- Consider acoustic mineral wool inside stud or ceiling cavities.
- Use the correct number and type of fixings for the board weight.
- Ensure the existing wall or ceiling can safely take the added load.
The board can be finished as part of the chosen plasterboard system. Always check that the fixing method is suitable for the structure being treated.
Important Note
This product helps improve acoustic performance by adding mass, but no single board can guarantee complete soundproofing on its own. Final results depend on the full system, workmanship, existing structure, flanking noise paths and whether the noise is airborne, impact or vibration-based.
FAQs
What is the total thickness?
The total thickness is 17mm.
What size is each board?
Each board is 1200mm x 1200mm, covering 1.44m².
What is the difference between the 5kg and 10kg version?
The 10kg version has a heavier acoustic barrier layer. This makes it better suited to higher-mass wall and ceiling soundproofing systems where stronger airborne noise reduction is required.
Is this board good for noisy neighbours?
Yes, it can help reduce airborne neighbour noise such as voices, TV noise and general household sound when installed as part of a suitable wall or ceiling system.
Can it be used directly on a wall?
Yes, it can be used as part of a direct wall lining where the existing wall is suitable. However, better results are usually achieved when the full system is chosen around the structure and noise problem.
Can it be used on ceilings?
Yes. It can be used in ceiling soundproofing systems, but ceiling installations must be planned carefully because the board is heavier than the 5kg version. Suitable fixings, support and safe handling are essential.
Does the 10kg barrier make a difference?
Yes. Extra mass is one of the key principles in airborne sound reduction. The 10kg barrier adds more mass than the 5kg version, making it the stronger option where acoustic mass is the priority.
Is this the same as a 30mm acoustic board?
No. This is a 17mm plasterboard and barrier composite board. Some competitor boards use additional foam layers or multi-layer constructions and are often 27mm to 30mm thick. This SPK board is designed to provide a higher-mass barrier-backed plasterboard in a slimmer format.
