Acousti-Tech Membranes improve energy efficiency through providing flooring insulation, which may lead to a reduced need of heating and cooling capacity and may assist in reducing the cost of acclimatising buildings.

Some products are suitable for floating floors as vapour barrier, preventing damage in the flooring installation.

Acousti-Tech Membranes provide long term durability, will not deteriorate and will maintain soundproofing properties over time.



Products contain small percentage of titanium dioxide. In 2006, the IARC reclassified titanium dioxide as possibly carcinogenic to humans (Group 2B). This issue of concern relates to the inhalation of pure powdered and ultra-fine titanium dioxide dust during manufacture, and is not considered a risk, as the TiO2 is not in a respirable form when bound into the product. Accordingly the sanding, grinding and other occupational production activities of products containing titanium dioxide may present issues if appropriate precautions are not taken. Precautions for workers such as reducing exposure to product in dust form and using appropriate Personal Protective Equipment (PPE) mitigate potential issues to low risk in accordance with an ecospecifier Risk Assessment. Refer to Material Safety Data Sheet for further information.


Product improves thermal comfort and also enhances acoustic noise conditions by limiting noise transfer.

Indoor Environment Quality

Manufacturer states that product is non toxic, anti microbial, rot resistant and does not emit significant amount of Volatile Organic Compounds (VOCs) through its lifecycle.

Emissions – Product contains large amount of recycled materials and is itself recyclable, reducing toxic and pollutant impacts compared to products made from virgin materials.

Product contains minor amount of aluminium. The production of alumina from bauxite ores uses a chemical treatment, known as the Bayer Process (see Glossary). The alkaline (fluoride containing) mist associated with this process may have adverse land and soil impacts.

Physical – Product's recycled content partly eliminates the physical pollution of oil extraction related to production of petrochemical based virgin polyester.

Mineral extraction of bauxite during the production of aluminium will disrupt landscapes and alter ecosystems. Because bauxite deposits are found near the Earth's surface, mining requires removal of topsoil and overburden before deeper excavation occurs.


Emissions – There are no known toxics emitted by this product that will impact aquatic and marine ecosystems.

Physical – Petrochemical production of virgin polyester can contribute to oil spills at sea.

Bauxite residues of red mud are disposed of in dams. Bauxite residue (chemically stable and non-toxic) is pumped to disposal dams where the mud is allowed to settle. The excess water is discharged into marine environments.


Greenhouse (GHG) – Placing Acousti-Tech Membranes within buildings, can assist in reducing energy heating and cooling loads, reducing energy consumption and therefore reducing greenhouse gas emission of fossil fuelled plants.

This product utilises minor amounts of virgin polyester, which is fabricated from fossil fuels. Fossil fuels generate both atmospheric pollutants and greenhouse gases on combustion. Product may contain significant amount of recycled polyester which requires less energy input than producing virgin polyester from scratch.

Alumina processing requires high-energy consumption and therefore greenhouse gas emissions are associated with the production of refined alumina, however the thermal benefits of product mainly offset this emission.

Operational efficiency –Product can assist in reducing energy cooling and heating loads, saving on energy and therefore reducing greenhouse gas emission of fossil fuelled plants.

Re-use Efficiency –  In floating floors, the membranes can be re-used when floor covering is replaced. Product is also recyclable, saving on energy consumption and greenhouse gas emission of production of virgin materials.

Toxics and Pollutants –  Product itself has no known toxic and pollutant impacts.

Product contains a small percentage of aluminium. The process of alumina refinement generates plant emissions, including coal dust, fugitive lime dust, alumina dust and aerosol generated from plant process liquor including fluorine/fluoride emissions that are known toxins.

Ozone Depletion – Product does not result in ODP in production or in use.

Urban Heat Island Effects – Not applicable.

Noise – Thermo-acoustical underlayment for hard surface will considerably reduce impact and airborne noise. See CSIRO test report resulting in a Lnw+C of 55/54 for the Acousti-Tech 3.3.


The use of minor volumes of virgin polyester generates biodiversity impacts through the atmospheric emissions generated during the refining and manufacturing processes of the virgin polymer. These have not been quantified in terms of impacts on biological systems, except in the case of oil-spill impacts which, while rare, can have significant localised impacts. The use of recycled polyester reduces these impacts.

Products contain a small percent of aluminium. Bauxite mining leads to modified soil profiles, topography and drainage which impacts natural vegetation and biodiversity impacts. Aluminium smelting has significant potential microorganism, animal and vegetation impacts up to within 5km of smelters.



Resource Efficiency

Large amount of the products components are derived from recycled or reclaimed materials. Polyester content come from post-consumer and post-industrial waste. The use of recycled materials decreases the need for virgin plastic production. The product itself can be recycled.

Made of synthetic fibre and needle punched technology, the durability is extensive. Product keeps its acoustical properties and structural stability over time.


In floating floors, the membranes can be re-used when floor covering is replaced. It is practically impossible to separate the membrane from the floor covering if it is glued down, however if the membrane is not glued to the substrate then re-using is possible for the next floating floor covering if relevant.


Product cannot be repaired.
