AWT - Flexible Acoustic Wall Ties

Acoustic Building Isolation Products

Acoustic brickwork and internal partition wall ties are designed to provide structural stability whilst attenuating noise and vibration between cavity walls.

General Notes:

• Check acoustic wall tie is suitable for the type of installation and cavity size i.e. external face brick/blockwork to inner cavity walls or studwork.
• Each masonry tie must be embedded a minimum of 50mm into brick/blockwork.
• Acoustic wall ties must be installed with rubber part upper most or “top” on masonry tie.
• Ensure wall loading and spacings do not exceed acoustic wall tie maximum working load of 0.75 kN.
• It is important that no oil or solvent be allowed to contaminate the wall tie rubber during installation (refer to data sheet DS 041 for details of natural rubber properties).

Design Features:

• Grade 304 stainless steel masonry ties, connecting bolts and washers.
• BZP mild steel “Z” and “L” brackets for internal partition walls.
• Natural rubber acoustic element ensures no metallic contact between external and inner brickwork and internal partitions.
• Load tested to 0.75 kN in tension, compression and shear.
• Masonry ties designed to BS EN 845 with drip feature and safety ends.
• Variable tie lengths and fixing options available to suit cavity widths 50 mm to 250 mm.
• It is recommended that acoustic wall ties are used in conjunction with acoustic wall bearing pads.

Typical Applications:

• Multiplex cinemas.
• Sound and recording studios.
• Hearing test rooms.
• Nightclubs.
