Rain Noise

Impact noise from rain can significantly increase the indoor noise levels. Rain noise is therefore a potentially important noise source which must be considered at an early point in the roof design in order to minimise disturbance within the building.

The addition of a mass layer is required in order to attain the highest acoustic performance levels for lightweight metal roof constructions. The Tecsound Acoustic Membrane offers additional mass whilst also providing inherent damping properties.

Testing has confirmed that Tecsound Acoustic Membrane provides improved acoustic performance in comparison with heavier, thicker, more expensive cementatious boards.


Tecsound Acoustic membrane is a unique synthetic material. It does not contain lead, EPDM or Bitumen. It is made from 68% recycled mineral fillers and is 100% recyclable


For flat roof applications, Tecsound Acoustic Membrane should be laid directly on to the metal decking, across the line of the profiles. The metal decking must be clean and dry. Align the membrane and extend the roll over the metal decking progressively. The reinforcing protecttion scrim works not only as a separating layer but makes the material easier to handle and safer to walk on when wet.

All membrane joints should be overlapped by 50mm as small openings can reduce the level of acoustic insulation.

The Tecsound Acoustic Membrane also doubles as a vapour control layer so in some applications no additional material is needed. Thermal insulation roofing boards are then applied. A mechanically fastened single-ply or other waterproofing membrane should then be installed in accordance with the manufacturer's requirements.

Day joints must be formed at the conclusion of each section of work to seal exposed edges of insulation boards and acoustic membrane.


Easily cut or shaped with a sharp knife.

Product Description

Tecsound Acoustic Roofing Membrane is a flexible, high density, visco-elastic polymer mass layer. When combined with rock fibre or PIR insulation, the product provides an inexpensive, high performance acoustic solution for flat roofing and built-up metal roofing systems (e.g. standing seam). It is an ideal solution for buildings requiring high levels of acoustic performance, including:

  • Cinemas
  • Airports
  • Concert halls
  • Stadiums
  • Retail and leisure developments
