Why PET Felt is Today’s Top Acoustic Material

Kirei

As acoustic design has become essential to great spaces, new acoustic design elements are coming to the fore. Felt made from PET plastic (Polyethylene Terephalate, or recycled plastic water and soda bottles) has leapt into the spotlight as a ‘go-to’ material that absorbs sound while offering a new palette for both visual and acoustic design.

As with all materials, not all PET plastic felt is created equal. We'll discuss the pros, cons, and differences in the explosion of offerings on the market with a few tips on making smart material choices. After all, PET felt has been successfully installed in high-profile projects and is now being accepted as a standard material in the commercial design industry.

WHAT IS PET FELT?

PET Panels are made of recycled PET (the type of plastic found in water or soda bottles) that becomes a soft, yet sturdy felt material. Durable in nature, PET felt offers great acoustic performance and can be recycled at the end of its life. As one of the originators of the PET felt product for architectural use, for well over 15 years in the Australian and Asian markets, Woven Image has recycled over 80 million plastic bottles into EchoPanel products.

Offering a wide range of solutions including panels, systems, tiles, partitions, and wallcoverings, PET felt products create versatile options that meet the needs of various spaces within commercial and residential settings—they can literally cover everything but the floor!

PET felt products such as EchoPanel provide an environmentally friendly acoustic design alternative that is both a stylish and functional design choice— like all products, just watch out for cheap imitations.

THE MINDFUL GENERATION

With so much of today’s mindful generation asking for quality and performance in every aspect of life—from the food consumed, to the products purchased, to the spaces designed—it is easy to see why PET felt should be your go-to material for acoustic treatments.

Mindful living is not an age or political bent, but a lifestyle that is permeating across generations; from Gen Z to Baby Boomers and beyond, we are in an era where everyone wants to live their best lives at work, play, and home.

We are seeing the demands of the mindful generation playing out within the food and beverage industry, as brands look holistically at everything from the food they produce to the atmosphere they create within their space.

Such is the case with Limitless Coffee & Tea, a cafe in Chicago’s River North neighborhood. Matching its mission to bring Chicago locals the world’s purest and cleanest coffee and tea, the company created a minimalistic space using EchoFold Mini to balance an intimate yet buzz-worthy acoustic atmosphere.

QUALITY AND USABILITY

PET felt is a very versatile material, available in an array of colors that can be customized to fit in a variety of spaces and configurations.

As with any commodity, PET felt has a wide spectrum of products and pricing available, so it’s essential to work with a manufacturing partner that stands behind their product and has experience in the marketplace. Further, the term “green” can range from zero to high percentages of recycled content, so it is imperative to do research and find which environmentally-friendly products works best for you.

The best PET felt products have no Red List chemicals contained in their production and very low VOCs. Some flame retardants used with PET felt can also have harmful chemicals in them so it’s good to check that as well. As with any product, those with HPDs and EPDs providing ingredient transparency and product quality and lifecycle analysis make for great partners with more assurances that what you are requesting is what you are getting. It can also help with LEED V4, Google Portico qualification, and WELL building standards.
