Siniat DB Sound Plasterboard 2400mm x 1200mm x 12.5mm TE (60)
What this product is for
Siniat dB Sound Plasterboard is engineered specifically for acoustic performance. It is used in stud partition systems, internal wall linings and ceiling installations where noise reduction between rooms is required. Common applications include office partitions, residential party walls, music rooms and commercial spaces where sound control is important. The plasterboard works by absorbing and dampening sound vibrations, making it more effective than standard plasterboard for acoustic purposes.
- Stud partition walls requiring acoustic performance
- Internal wall linings in residential and commercial buildings
- Suspended ceiling systems
- Rooms requiring noise reduction between spaces
Sizing and pack contents
Each sheet measures 2400mm length by 1200mm width by 12.5mm thickness. The pack quantity is 60 sheets. Calculate your coverage by multiplying sheet dimensions: each sheet covers 2.88 square metres. For a typical room, determine total wall and ceiling area in square metres, then divide by 2.88 to establish the number of sheets required. Always add 10 percent extra for waste, cuts and future repairs.

Pre-installation checks
Before fixing, inspect all sheets for damage and ensure your supporting framework is level, square and properly braced. Check that studs or joists are at the correct spacing and that any services (electrical, plumbing) are positioned and protected appropriately. Store plasterboard flat and dry on site, protected from weather and moisture. Ensure you have suitable fixings (plasterboard screws or nails), joint compound, tape and finishing materials ready. Have adequate workspace for handling large sheets safely.
