ACOUSTIC UNDERLAY for FLOORING

IMPACT SOUND INSULATION for TILES, TIMBER, CARPET, RESILIENT FLOORING & SCREED BEDS

Regupol acoustic products significantly reduce impact sound levels within living and working environments and, for many years, Regupol underlays have represented the preferred choice for architects, project engineers and acoustic specialists. Every building has different noise parameters influenced by factors such as the Building Code of Australia, the specifying architect / developer, local council and strata by-laws etc. For this reason, Regupol offer an extensive range of acoustic underlay products to satisfy different scenarios. In addition to noise reduction benefits, Regupol underlays also enhance living and walking comfort while improving the resilience of the top floor.

Acoustic Compliance

REGUPOL® ACOUSTIC UNDERLAYS ARE:

  • BCA Part F.5 Compliant
  • Tested to ISO 140.6-1998
  • BCA Part F.2 Compliant
  • Rated to AS/NZ 717.2-2004

During the design process, acoustic engineers require laboratory results to show confidence and assurance that the flooring system will work. Currently in Australia, there is an abundance of test results for walls, but very little for floors. Regupol® (Australia) Pty Ltd have taken the initiative to test their Acoustic Underlays in the laboratory. The tests have demonstrated conformity with the Building Code of Australia (BCA).  Different types of underlay, with different floor surfaces and various thicknesses were tested. The tests were conducted in the CSIRO laboratories at Highett Victoria.

The BCA requires a minimum performance rating of Ln,w < 62. This rating is a measure of the flooring system’s ability to supress footfall and noise and from other impacts. The lower this rating, the higher the impact sound reduction performance of the system. A building solution will comply with the BCA if it satisfies the performance requirements.  Regupol provides a building solution which satisfies the performance requirement of Ln,w < 62.

The Unit of Measurement Explained:

L’n,W – Weighted Normalised Impact Sound Pressure Level.

In addition, a building solution which complies with the “Deemed-to-Satisfy Provision” is therefore deemed to comply with the performance requirements. The “Deemed-to-Satisfy Provision F5.3” of the BCA states:

F5.3 DETERMINATION OF IMPACT SOUND INSULATION RATINGS

A floor in a building required to have an impact sound insulation rating must:

i) have the required value for weighted normalised impact sound pressure level with spectrum adaptation term (Ln,w) determined in accordance  with AS/ISO 717.2 using results from laboratory measurements; or

ii) comply with specification F5.2

F5.4 SOUND INSULATION RATING OF FLOORS

A floor in a Class 2 or 3 building must have an RW+Ctr (airborne) not less than 50 and an L’n,w (impact) not more than 62 if it separates –

i) sole-occupancy units; or

ii) a sole occupancy unit from a plant room, lift shaft, stairway, public corridor, public lobby or the like, or parts of different classification.

GECA (Good Environmental Choice Australia)
Recycled materials and products such as Regupol, can play a major role in the design & construction of environmentally friendly & sustainable buildings. To ensure this, we have had many of the Regupol Impact Sound Underlays GECA Certified for their environmental contribution.  The independent verification performed by GECA shows that the acoustic range of Regupol recycled products are environmentally preferable and meet the requirements of GECA 25-2011 v2 – Floor Coverings Standard.

Additionally, the GECA 25-2011 v2 Floor Covering is recognised by the Green Building Council of Australia (GBCA) under their assessment framework for product certification schemes. The selected Regupol products will provide a Level A sustainability factor weighting (100%) within the Green Star Sustainable Products Calculator.
