[Refer to the letter of endorsement from Winstone Wallboards dated 23rd August 2015]
In addition to this, SRP™ Whisperwall™ Acoustic SRP™ Stud has been confirmed as an acceptable substitution in GBS 60 from GIB® Fire Rated Systems. Winstone Wallboards, in their letter dated 11th June 2014, confirm the -/60/60 FRR Fire Resistance Rating for SRP™ Whisperwall™ provided that the inner layer of 13mm GIB Noiseline® is fastened to the SRP™ Whisperwall™ Acoustic SRP™ Studs in accordance with the SRP™ Product Catalogue and GBS 60 from GIB® Fire Rated Systems specification. In cases, where an additional layer of 10mm GIB Noiseline® is used, the FRR will be maintained and the inner layer of 13mm GIB Noiseline® does not require plaster stopping.
