The Floor and Ceiling Soundproofing System: SoundDeck CLD
PCT Floor and Ceiling Soundproofing System Solution for new build timber frame apartment floors and ceilings
The SoundDeck CLD Floor and Ceiling SoundproofingSystem comprises a timber based, high performance overlay board and an innovative acoustic ceiling hanger to provide exceptional acoustic performance in new build joisted floors.
The system has exceeded the requirements of Part E (England and Wales) and Section 5 (Scotland) and can achieve up to 3 Code credits on a PCT basis. The single layer acoustic floor uses proven damping technology, is solid underfoot and fast to install. Made from timber products it is sustainable and avoids the Health and Safety issues associated with dust generated by cutting alternative dry screed board solutions. SoundDeck Acoustic Hangers provide an acoustic ceiling with an integral void for services, avoiding the need for both resilient bars and a sacrificial ceiling.
SoundDeck CLD boards
SoundDeck CLD boards consist of two separate layers of moisture resistant chipboard isolated but bonded together by visco-elastic sound damping strips with a resilient foam layer on the underside. The boards are 2400mm x 600mm x 36mm and are tongued and grooved on four edges. The patented Constrained Layer Damping technology damps vibrations and attenuates impact and airborne noise passing through the floor.
SoundDeck Acoustic Hangers
SoundDeck Hangers are manufactured from galvanised steel and are profiled and shaped in such a way that sound waves are weakened in their transit through the component.
Carefully positioned slots prevent a direct transmission path. The hanger system provides a void for services and is cheaper and faster to install than a resilient bar system with a sacrificial MF ceiling. If no service void is required a standard resilient bar can be used instead.

Ceiling Hangers SoundDeck Acoustic Hangers fixed at 600mm centres along I joists (and to within 150mm of perimeter walls) with 4 No. 3.5mm x 35mm woodscrews (to BS1202:Part 1:1994) per hanger.
Ceiling Battens 45mm x 45mm C16 softwood timber battens screwed to hangers with 3.5mm x 35mm woodscrews. SoundDeck Acoustic Hangers can be spaced up to 1200mm apart along the length of the ceiling battens.
Ceiling Lining Two layers of 15mm fire resistant glass reinforced plasterboard with minimum density of 12kg/m2 per layer. (Siniat GTEC Fireboard – formerly Lafarge Firecheck – or equal)
Perimeter Flanking strip CMS Danskin `L` shaped flanking strip to perimeter.
The SoundDeck CLD System has been demonstrated to exceed the sound insulation requirements of Approved Document E of the Buliding Regulations and Scottish Section 5 : Noise (2010).
The following accessories are required for the successful installation of the SoundDeck CLD system:
SoundDeck Ceiling battens
C16 softwood ceiling battens are screwed into the SoundDeck Acoustic Hanger with 3.5mm x 35mm woodscrews to BS1202:Part 1:1994.The ceiling battens are 45 x 45 x 2400mm for ease of handling and are PEFC Certified as standard.
‘L’ shaped flanking strip
6mm thick preformed `L` shaped acoustic foam supplied in strips 1.8m long packed in bags containing 100 linear metres. The strip prevents contact between the floating floor and the perimeter. It is lightly trapped between the bottom of the skirting and the top of the floating floor with the excess neatly trimmed of.
CMS Danskin D3 adhesive is a high quality, resin based wood adhesive which provides a high strength impact resistant bond. It conforms to the international standard EN204 (D3) and BS4071 for creep resistance and is supplied in 1 litre bottles.
