Signature has been fully acoustically tested in UKAS accredited acoustic laboratories to the procedures of ISO140/ISO717 and has demonstrated the following performance levels:

Steel faced full height modules, empty cavity:
41dB RW, test report BGATR 1655

Steel faced full height modules incorporating a single layer of 25mm acoustic foam to cavity: TO BE ADVISED

Steel faced full height modules incorporating two layers of 25mm acoustic foam to cavity:
49dB RW, test report BTC 2216A

Double framed glazed full height modules, incorporating two panes of 6mm toughened glass:
39dB RW, test report BGATR 1662

Double flush glazed full height modules, incorporating two panes of 6mm toughened glass:
40dB RW, test report BTC 3258A

Full height single doorset, incorporating a 44mm thick solid core laminated doorleaf:
34dB RW, test report BGATR 1663

These figures indicate the performance of the Signature partition elements tested under strict laboratory conditions. They are only indicative of actual site performance. Due note should be taken of losses via flanking transmissions onsite, via:

- ceiling voids
- floor voids
- trunking and ductwork
- fasade transmissions via window mullions
