Sound Rating Requirements are party wall sound barriers, resilient mounts (sound absorbing rubber) brackets, sound insulation, Studio/ music room sound barriers, Theatre/Cinema Rooms, Meeting Rooms, Rest Rooms and Rumpus/Play Rooms.

Resilient Mounts are used in conjunction with steel sections for acoustic walls and soundproof rooms where a high level of noise reduction is required.  Acoustic attenuation in wall construction is achieved by a combination of density or mass to block and reflect sound as well as insulation in cavities to absorb sound to minimise noise transfer through the wall.  Noise, particularly low frequencies can transfer through solid structures.  This means that sound can pass through the wall studs, floor and top plates into the next room.  

Resilient Mounts are furring channel fixing clips with a fastener that is isolated by acrylic pads.  These are affixed to the wall frame with furring channels attached and acoustic plasterboard is then mounted to the frame. This method dramatically reduces impact noise and structure borne noise with minimal increase in wall thickness.

Perforated Plasterboard has been designed for use on ceilings and walls where an increased level of sound attenuation is required.  As the name implies, the acoustic properties of the board absorbs sound to reduce echoes and reverberation.  The long edges of the panels are recessed for flush jointing to a smooth, continuous surface.  Perforated Plasterboard is made up of a gypsum plaster core that is wrapped in heavy-futy linerboard paper with bonded edges.  The board is often applied to commercial and industrial premises.
