How and where to use guide
Siniat DB Sound Plasterboard 2400mm x 1200mm x 15mm TE (50)
Typical applications
Siniat dB Sound Plasterboard is specified for internal partitions, stud wall linings, and ceiling systems where acoustic performance is required. Common uses include separating residential flats or apartments, creating quiet office spaces, reducing noise between commercial units, and lining party walls. The 15mm thickness provides a balance between acoustic effectiveness and practical handling on site.
- Internal stud partition systems
- Wall lining and dry-lining applications
- Suspended ceiling systems
- Party wall construction between residential or commercial spaces
- Noise reduction in offices and commercial buildings
Installation and on-site handling
Install Siniat dB Sound Plasterboard using standard dry-lining techniques with timber or metal stud framing. The 2400mm x 1200mm sheet size is designed for efficient coverage and minimal waste. Ensure studs are spaced at appropriate centres (typically 400mm or 600mm) and that the plasterboard is fixed securely with drywall screws or nails. Stagger joints between sheets to avoid weak points. For maximum acoustic benefit, consider combining with resilient channels, acoustic sealant, or cavity insulation as part of a complete sound-control system. Handle sheets carefully on site to avoid damage that could compromise acoustic seals.
- Fix securely to timber or metal studs with drywall screws or nails
- Stagger joints between adjacent sheets
- Seal all joints and penetrations with acoustic sealant for optimal performance
- Combine with resilient channels or cavity insulation for enhanced sound reduction
- Protect edges and surfaces from damage during transport and installation
Performance and limitations
As a Type DI plasterboard to EN 520, Siniat dB Sound Plasterboard delivers superior acoustic performance compared to standard plasterboard. However, acoustic effectiveness depends on correct installation, proper sealing of gaps and joints, and the overall system design. A single layer provides meaningful noise reduction, but for critical applications or higher sound reduction requirements, consider double-layer systems or additional acoustic measures such as cavity insulation. Performance will be compromised if joints are not sealed or if the plasterboard is damaged.
- Acoustic performance is system-dependent and requires proper installation
- Single-layer application suitable for moderate noise control
- Double-layer systems recommended for higher sound reduction requirements
- All joints, gaps and penetrations must be sealed for optimal performance
- Damage to sheets or poor sealing will reduce acoustic effectiveness
Finishing and maintenance
Once installed, Siniat dB Sound Plasterboard is finished like standard plasterboard with joint compound, tape and paint or other surface finishes. Ensure all joints are properly taped and filled to maintain both acoustic and visual quality. The plasterboard itself requires no special maintenance once in place. Avoid drilling or cutting unnecessarily after installation, as this can compromise acoustic seals. If future penetrations are needed for services, use acoustic sealant around pipes, cables or outlets to maintain sound reduction performance.
- Finish with standard joint compound and tape
- Decorate with paint or other finishes as required
- Seal any service penetrations with acoustic sealant
- Avoid unnecessary cutting or drilling after installation
- No ongoing maintenance required once properly installed and finished
