How and where to use guide
Siniat DB Sound Plasterboard 2400mm x 1200mm x 12.5mm TE (60)
Typical applications
Siniat dB Sound Plasterboard is primarily used in acoustic partition systems, party wall linings and suspended ceiling applications. It performs well in multi-storey residential buildings where sound insulation between units is required, as well as in commercial and office environments where noise control between spaces is important. The product can be used in both single and double-layer applications depending on the acoustic performance required.
- Party wall linings in flats and apartments
- Office partition systems
- Studio and music room construction
- Suspended ceiling linings
- Commercial space acoustic treatment
- Refurbishment of existing walls and ceilings
Installation and fixing
Install Siniat dB Sound Plasterboard using standard stud partition or lining frame systems. The 2400mm x 1200mm sheet size is designed for efficient coverage with minimal waste. Fix boards to timber or metal studs using drywall screws or nails at 300mm centres, ensuring boards are fully supported across their width. Stagger joints between layers if installing double-layer systems for improved acoustic performance. Ensure all edges are properly supported and sealed to maintain acoustic integrity.
- Use drywall screws or galvanised nails for fixing
- Space fixings at 300mm centres maximum
- Stagger board joints in multi-layer applications
- Seal all joints and penetrations with acoustic sealant
- Support board edges fully on studs or noggins
- Allow boards to acclimatise to site conditions before installation
Performance and limitations
The 12.5mm thickness provides enhanced acoustic performance over standard plasterboard whilst remaining practical for standard partition widths. Acoustic performance is optimised when boards are installed as part of a complete system including cavity insulation and proper sealing. Performance will be compromised if joints are not sealed, if there are gaps around penetrations such as pipes and cables, or if the cavity is left empty. For maximum sound reduction, consider combining with mineral wool cavity insulation and acoustic sealants.
- Performance depends on complete system installation
- Seal all joints, gaps and penetrations
- Cavity insulation enhances acoustic performance
- Not suitable for wet areas without additional protection
- Double-layer installation provides better performance than single layer
On-site handling and storage
Store boards flat and horizontally on a level, dry surface to prevent warping and damage. Keep boards protected from moisture and weather during transport and on site. Handle carefully to avoid impact damage to edges and corners, which can compromise installation quality and acoustic sealing. Ensure adequate workspace for cutting and fitting, and allow boards to reach room temperature and humidity before installation to prevent dimensional movement after fixing.
- Store flat on level, dry ground
- Protect from rain and excessive moisture
- Handle carefully to avoid edge damage
- Allow acclimatisation time before installation
- Keep away from wet trades until fully installed
