ROCKWOOL Acoustic Membrane

Application

Suitable for flat roofing and built-up metal roofing systems. Suitable for buildings requiring high levels of acoustic performance such as cinemas, live music venues, airports, schools and hospitals.

Description

Complimenting the acoustic performance of HARDROCK® Multi-Fix, ROCKWOOL Acoustic Membrane is a high performance, sound deadening polymeric layer used to enhance the performance of an acoustic roof build-up. An suitable acoustic solution for buildings requiring an exceptionally high acoustic performance, such as schools, hospitals, cinemas, airports, arenas and leisure developments.

Features and benefits:

  • Excellent acoustic properties.
  • Supplied as a roll for faster installation and fewer.
  • Cost-effective.
  • Suitable for new build and refurbishments.

Acoustic Performance:

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

Using ROCKWOOL Acoustic Membrane in conjunction with ROCKWOOL roofing products results in improved sound insulation levels across the frequency range. Testing has confirmed that ROCKWOOL Acoustic Membrane provides improved acoustic performance in comparison with heavier, and thicker cementitious boards. Please contact ROCKWOOL for technical advice and supporting test data on typical constructions.

Application:

Suitable for flat roofing and built-up metal roofing systems. Suitable for buildings requiring high levels of acoustic performance such as cinemas, live music venues, airports, schools and hospitals.
