Where possible, and without compromising on quality, Acoufelt pursues sustainable practices in manufacturing that close the loop on the circular economy through careful and considered raw material sourcing. Acoufelt’s primary material components; FilaSorb™ felt and QuietBack™ carpet tiles, are both made from regenerated PET fibres with a minimum of 60% recycled content, and our BarrierBack™ carpet tiles are also made from ECONYL® regenerated fibres. Acoufelt are also committed to testing our acoustic products against a number of internationally recognised environmental and human safety standards and accreditations, to ensure our products can be manufactured safely, and are ultimately safe for human use. You can read more about these standards and accreditations below. 

Our Manufacturing

We are committed towards environmental sustainability through our manufacturing processes meeting the International Standards of ISO 14001 and ISO 9001. We use reclaimed materials in the product design process, and ensure products are recyclable at the end of their useful life.

Recycled Yarn

Sourcing Regenerated PET

We source clean, quality regenerated PET fibres for use in our acoustic products. These fibres are made from recycled PET bottles that would normally go to landfill, closing the loop on a valuable resource. These are used in both our FilaSorb™ and QuietBack™ products. 


Sourcing ECONYL

We use ECONYL® regenerated nylon fibres in our BarrierBack™ carpet tile collections. ECONYL® fibres are sourced from waste such as fishing nets, fabric, carpet flooring and other industrial plastics, which is rescued from seas and landfill, and then regenerated into carpet and textile yarn of original purity. 

The ECONYL Regeneration process is as follows:



Waste such as fishing nets, fabric scraps, carpet flooring and industrial plastic from landfills and oceans is sorted and cleaned to recover the maximum amount of nylon as possible.



Through a radical regeneration and purification process, the nylon waste is recycled right back to its original purity, displaying the same properties as virgin nylon.



The regenerated nylon is processed into carpet yarn and textile yarn.



Manufacturers like us use the regenerated nylon to create brand new products. Once ECONYL® – based products reach the end of their useful life, they can re-enter the regeneration system for rescue.

Environmental standards and accreditationS

SCS Global Services

SCS is an international leader in third-party certification and standards development in environmental, sustainability and quality performance. Through auditing, certification, testing, life cycle assessment, training, and strategic consulting services, SCS Global helps organisations affirm and communicate their sustainability success stories.

Acoufelt FilaSorb™ products receive Indoor Advantage Gold certification for Indoor Air Quality. The Indoor Advantage and Indoor Advantage Gold standard aligns with both ANSI/BIFMA M7 and X7.1, and CA 01350. It is recognised by the EPA and GSA, and qualifies for many building rating systems, including LEED v4, BREEAM, WELL Building and Living Building Challenge.

FilaSorb™ products achieve Indoor Advantage Gold certification through meeting the high standard for California Department of Public Health (CDPH) compliance. Product compliance is determined by comparing the calculated emission concentration or emission factor to the applicable Volatile Organic Compound (VOC) emission criteria.

Purchasers and consumers can be assured that products labelled with the SCS certification marks are consistently meeting the performance requirements of this standard.

Living Future Australia ‘Declare’ Program

The Living Future Institute of Australia is part of a global movement revolutionising the built environment with regenerative design. As an Affiliate of the International Living Future Institute (ILFI), LFIA is guiding the Australian built environment industry with ILFI programs including the Living Building Challenge (LBC)® and Declare. Through Acoufelt’s corporate membership, we are committed to growing our knowledge and engaging in programs that are redefining the green building movement, including ILFI’s Declare certification.

Declare provides a free and simple database of the healthiest products on the market. The transparency labels help Living Building Challenge project teams meet stringent materials requirements within the world’s most rigorous building performance standard.

The Red List represents the “worst in class” materials, chemicals, and elements known to pose serious risks to human health and the greater ecosystem that are prevalent in the building products industry. ILFI and LFIA believe that these materials should be phased out of production due to human and/or environmental health and toxicity concerns.

Acoufelt QuietBack™ carpet tiles and FilaSorb™ collections have both received “LBC Red List Free” declaration status – having disclosed 100% of product ingredients at or above 100 ppm (0.01%) in the final product and not containing any Red List chemicals. They have been shown to meet the requirements of the Living Building Challenge (LBC) Red List Imperative.

USGBC ‘LEED’ program

Leed Logo

Sustainable textile furnishing materials are recognised as contributing to green building practices. Made from a minimum of 60% recycled content, all of Acoufelt’s acoustic products exceed the criteria set by the USGBC (United States Green Building Council) which recognises contributions made to Leadership in Energy and Environmental Design (LEED). Therefore, users of Acoufelt products can earn environmental points from LEED for their building projects.

View the table below to determine how many LEED points you can earn with any Acoufelt product:

LEED Credit
MR credit 4.1 (recycled content 10%)
Products are manufactured using a minimum of 50% post consumer recycled materials
MR credit 4.2 (recycled content 20%)
Products are manufactured using a minimum of 50% post consumer recycled materials
MR credit 5.1 (regional materials 10%)
Manufactured within 500 miles
MR credit 5.2 (regional materials 20%)
Manufactured within 500 miles
MR credit 3.2 (indoor air quality)
Low VOCs Emission
LEED Credit
Potential LEED Credit
EA: Energy Performance
(Health Care)
EQ: Acoustic Performance
(Health Care)

CRI Green Label Plus

CRI’s Green Label program tests carpet, cushions and adhesives to help specifiers identify products with very low emissions of Volatile Organic Compounds (VOCs). The CRI Green Label Plus logo indicates a product has been tested and certified by an independent laboratory and has met stringent criteria for low emissions. The test methodology has been developed in cooperation with the US EPA and has been adopted by the American Society for Testing and Materials (ASTM) as D5116 – Standard Guide for Small Scale Environmental Chamber Determinations of Organic Emission from Indoor Materials/Products.

All of Acoufelt’s carpet tiles meet the requirements for Green Label Plus certification under Indoor Air Quality Testing. This means that architects, builders, specifiers and facility managers have the assurance that all Acoufelt carpet products meet the most stringent criteria for low chemical emissions.
