GypWall QUIET SF

GypWall QUIET SF is an acoustic, non-loadbearing single frame acoustic separating wall system able to exceed the requirements set by the applicable Approved Document E, but also meet the requirements set in the Building Bulletin 93 (Education) and Health Technical Memorandum 08-01. The system can be used in both new build and reconstruction projects, being a single stud framework it will not take additional floor space, being able to accommodate the services within stud cavity. It is a resilient and durable system offering a sound insulation up to Rw + Ctr 59dB and a fire resistance of 60-120 minutes.

Certain consideration should be taken into account upon installation, including:

• heavy fixtures and service positions should be planned at the frame erection stage, all penetrations fire stopped and timber sole plates installed if dealing with an uneven floor;
• in case the room layout includes structural steelwork, there might be a slight loss of acoustic performance through the steelwork;
• rock wool should be placed within the cavity in order of providing adequate flame and some closure;
• high acoustic performance is achieved by using separating resilient bars, however it must ensured that the screws do not come in contact with stud framing and that the services do not form a bridge between the lining boards;
• if dealing with an uneven floor, a 38mm timber sole plate should be installed, while when installing a new screeded or concrete floor, installing a damp-proof membrane should be taken into account;
• deflection heads may be required for the supporting floors and underside of the roof structures;
• when accommodating services, every penetration should be carefully planned and positioned in order of avoiding such penetrations to affect the system’s fire resistance and acoustic performance; when installing fire dampers or accompanying services, the weight and size of the damper must be taken into consideration in order of determining its support system; electrical services should be installed in accordance with BS 7671 whereas high performance socket box detail can be added for better sound performance;
• in order of maintaining the acoustic performance of the system, door and other openings must be planned in detail while heavy acoustic doorsets can include some additional support;
• lightweight fixtures can be installed directly to the partitions while medium ones may require additional fixing channels.
