CSR – Building a better future

As industry leaders it is our responsibility to reduce our footprint and strive for a future with minimal impact on the planet. Look at our latest Sustainability Report for more information on our sustainability record, challenges and opportunities.



Brand Sustainability Summaries

“Sustainability is more than a word” and Ecophon is leading by example, working towards a true circular business model and net zero emissions by 2050.

In innovating new and radical ways to further reduce its footprint, it is also working to transform sustainability standards across the industry, with full transparency a cornerstone of its activities

Gyprock continually pushes for greater sustainability in its product range and has led the way in gaining Good Environmental Choice Australia (GECA) accreditation for its products, which continue to meet the needs of residential and commercial green building projects.

Gyprock is committed to sustainable manufacturing processes, including lowering energy consumption, and recycling more than 95 per cent of its manufacturing waste back into production or into by-products such as soil conditioners for the agricultural industry.

In support of the Living Building Challenge Declare program, Himmel is committed to transparency in its product and materials selection.
Declare provides a clear and informative “nutrition label” for building products by asking:

  • Where does a product come from?
  • What is it made of?
  • Where does it go at the end of its life?

Auditory enjoyment that doesn’t cost the Earth.

Although sound itself is never seen – the results of being a sustainable business are. CSR Martini are industry leaders in the way our products technically enhance the daily spaces we live in and the way we help reduce plastic waste and pollution.

Environmental Product Declaration.

The EPD is a testimony to the high-performance, low impact nature of our products and processes. Independent contractors, Edge Environment, were commissioned to complete a Life Cycle Assessment (LCA) for 80 of our products. An LCA is a rigorous scientific analysis of raw material (such as polyethylene terephthalate fibre blends) density and manufacture method. Through this, CSR Martini products become approved for use in new and existing Greenstar projects.

Our products are regularly used in some of the most challenging acoustic spaces. This includes: recording studios, open learning spaces, concert halls and auditoriums. It’s our commitment to quality, innovation and sustainability that has built our reputation of being a trusted name in the industry.

CSR Martini Products contribute to sustainability by:

  • Minimal waste is generated in the manufacturing process.
  • High reusable potential.
  • Volatile organic compounds (VOCs) generated in the manufacturing process is classified as low (0.01 mg/m3).
  • No ozone-depleting gases are used.
  • No red list chemicals are present.
  • Safe, non-irritant, non-toxic, and non-allergenic.


Product Health Declaration

100% of CSR Martini products have a full, easily accessible product health declaration for health assessments. Our hands-on approach to manufacturing gives us the ability to tell the story of all the materials used in our products.
With full transparency, you can feel confident in the integrity and safety of all our products.

Global Green Tag International Pty LTD (Global Green Tag) awarded CSR Martini a Platinum Health Rating – the highest health level achievable. We’re incredibly proud of this award, but our work is never done. We are constantly exploring new ways to enhance the safety in all our acoustic products. Use this link to get our insulation certificates for our products (select an individual product and click on the “Professional” tab).


CSR Martini participates in the Living Building Challenge Declare program. You can make the right acoustic product decisions when designing and specifying for your projects by selecting high performance products that have Declare material documentation available.

Declare Labels provide a clear and informative “nutrition label” for building products by answering three simple questions:

Where does a product come from?

What is it made of?

And where does it go at the end of its life?

Declare aligns with our commitment to transparency in support of the Living Building Challenge’s Red List and Appropriate Sourcing Products in our dECO portfolio of high performance sustainable acoustic products have Declare Label.

Green Tag™ approved for GreenStar® Projects

More people are becoming ecologically aware, selecting design processes and materials that minimise their environmental footprint. We believe that this mindset is a launchpad for how we can all work together to make a global change.

Our range of products have achieved the highest achievable award of GreenRate | Level A (verified ISO 14024 and ISO 17065) making our GreenTagTM products ideal for GreenStar® Projects.

Certified by one of the world’s most robust, trusted and widely recognised ecolabels, OWA’s mineral fibre ceiling tiles are “fitness – tested” under a rigorous Green Tag program that uses the most advanced scientific methodology. GreenTag has earned the trust of buyers and green building councils, certification bodies and governments around the world.

In recognising its responsibility to make a genuine commitment to the environment, Rondo constantly reviews its environmental footprint.

From minimising energy consumption from fossil fuels and reducing waste, to reviewing new technology that could reduce energy consumption and landfill, Rondo aims to achieve a high standard of environmental care within all areas of its operations.

Troldtekt acoustic panels for ceilings and walls are made of certified wood (PEFC TM or FSC ® C115450) a pure, natural material and cement from Danish raw material sources. Troldtekt is thus a natural product, and its sustainability throughout the product life cycle has been documented.

Cradle to Cradle Gold
In 2022 the full range of Troldtekt acoustic panels in both natural wood/natural grey and painted in standard colours advanced to Gold status within the Cradle to Cradle sustainable design concept. For more than a decade, Cradle to Cradle has been at the heart of our business strategy. Since 2012, we have, for example, achieved the following Cradle to Cradle objectives:

  • Material health: We are able to document that Troldtekt acoustic panels do not contain any substances that are harmful to human health or the environment. For a long time, we have – together with our paint supplier – worked to find a paint recipe that uses newer and more sustainable preservation technology. We have now succeeded, and in 2022 we therefore advanced to the best Cradle to Cradle category (Platinum) in material health. At the same time, we advanced to Gold in the overall product certification.
  • Material reutilisation: Troldtekt acoustic panels are documented as being free of harmful substances and can therefore safely be returned to the biological cycle. Our cement supplier, Aalborg Portland, uses offcuts from our factory as a raw material in new cement. The aim is for this cement-bonded wood wool waste scheme to be scaled to include building site and demolition waste.
  • Renewable energy: We have based our production on renewable energy (100 per cent wind power and biofuels in our own boiler). In 2021, 98 per cent of the energy consumed at our high-tech factory came from renewable sources.
  • Social fairness: We joined the UN Global Compact back in 2010 and report each year on our initiatives within the field of social responsibility.

Troldtekt based on FUTURECEM™
The cement in Troldtekt cement-bonded wood wool is responsible for the strength, durability and fireproofing properties of the acoustic panels. However, the cement also accounts for virtually their entire carbon footprint. Therefore, it is something of a breakthrough that it is now possible to choose Troldtekt based on FUTURECEM cement from Aalborg Portland.

Using FUTURECEM, it is possible to look after the climate while preserving all the well-known advantages of Troldtekt acoustic panels.

Cement with a reduced footprint

FUTURECEM exploits the synergies between calcined clay and limestone filler. In this way, much of the fired clinker in the cement can be replaced, resulting in cement that has an approx. 30 per cent reduced carbon footprint.
Over their entire product life cycle, the carbon footprint of Troldtekt acoustic panels based on FUTURECEM is:

26 per cent lower than that of Troldtekt based on grey cement.
38 per cent lower than that of Troldtekt based on white cement.
