Colour and Finish
Cara, Lucia and Lucia CS fabric ranges are available as standard in a wide range of colours. Alternatively, dB Absorbers can be covered with a client’s own choice of fabric, subject to it being of a suitable quality and having the required acoustic properties.
Operating Temperature
Suitable for use at normal building temperatures.
Fire Performance
MelaTech® foam complies with the Class ‘O’ requirements of the Building Regulations, when tested to BS476: Part 6: 1981 and Part 7: 1987.
Cara, Lucia and Lucia CS fabrics meet the requirements of Class 1 Surface Spread of Flame when tested to BS476: Part7: 1997 (As Amended). The composite absorbers have not been fire tested.
Thermal Conductivity
0.035 Wm/K @ 10oC
Packaging, Handling and Storage
Two dBAbsorbers® are packed with fabric-face to fabric-face in a non-returnable polythene bag. Packs are laid flat and delivered on non-returnable wooden pallets with plastic corner protectors. Absorbers should be stored inside and under cover in a dry, well-ventilated area protected from dirt and dust. Pallets should be kept level and not double-stacked. Extreme care should be taken when handling, to avoid soiling the fabric.
Application and Fixing
Dimensional changes may occur in dB Absorbers™ dependent on the relative humidity of the area in which they are being installed Absorbers should therefore be left to acclimatise for 24 hours prior to installation. For best results it is recommended that panels are bonded into place with a minimum 100mm spacing between them using a suitable adhesive (such as Soudal Fix All Crystal).
Care and Maintenance
The surface of dB Absorbers® can be cleaned periodically with a vacuum cleaner. Under no circumstances should they be submerged in water or subjected to a high pressure water jet spray. Stains on the fabric covering may be treated with an appropriate non-solvent based cleaning solution applied in accordance with the manufacturer’s instructions.
dB Absorbers® are available to order and should only be fitted by suitably qualified tradesmen or specialist contractors.
