  • Plant rooms.
  • Classrooms.
  • Lecture theatres.
  • Gymnasiums.
  • Swimming pools.
  • Arenas.
  • Factories.

Description

Textured face acoustic masonry blocks which provide high levels of sound absorption.

Manufactured from cement, specially sourced sound porous aggregates (65% recycled secondary aggregate content), an integral waterproofing and colour pigment.


Features and benefits:

  • Sound-absorbing texture.
  • Delivers a noise reduction coefficient (NRC) of 0.55 αw.
  • Effective sound control qualities, especially in the high-frequency sound range.
  • Satisfies the requirements of Building Bulletin 93 (BB93).
  • Minimal maintenance required.
  • Waterproof, and will retain a fresh, clean appearance.
  • Non-combustible, and will not contribute to the spread of flame.
