AIM’s cavity barriers selected for ‘path- breaking’ university accommodation
A IM (Acoustic & Insulation
Manufacturing) has supplied Wall Cavity Barriers and open state cavity barriers (OSCBs), along with technical support, for a ‘path-breaking’, 900- room student accommodation development at the University of West England Bristol’s Frenchay Campus. The new-build,
low-carbon design
development, which includes three buildings, six stories high, is to help meet demand from students for high-quality on-campus accommodation. The fi rst rooms will be available from this September. Designed by Stride Treglown, the project’s main contractor is Vinci Construction.
AIM worked with Maple Sunscreening on the rainscreen facade system assembly from the ground fl oor upwards, which is mainly cassette panels with AIM’s OSCBs incorporated horizontally and
AIM’s
Wall Cavity Barriers installed vertically. AIM also supplied and supported installers
systems, AIM’s OSCBs allow free airfl ow and drainage and improve fi re safety, providing fi re resistance of up to two hours insulation and integrity in suitably supporting structures. In the event of a fi re, heat activates an intumescent strip which expands quickly to fully close the cavity.

Manufactured from high density Rockwool stone wool and faced with the higher performance intumescent strip, AIM’s OSCB range provides either a 60 or 120-minute rating for both integrity and insulation. The OSCBs are an effective barrier to the passage of hot smoke as well as fi re. The AIM range has been tested to TGD 19 and the general principles of BS EN 1363-1. They have been exposed to BS 8414 Fire performance of external cladding systems fi re tests and assessed to BR135 to achieve pass results with a variety of third-party cladding systems.
