Introducing Collective Core™: The Next Chapter in PET Acoustics
July 1, 2026

For more than a decade, The Collective has been helping shape the future of PET acoustics. Since 2014, we've worked alongside architects and designers to deliver sustainable acoustic solutions that balance performance, aesthetics and responsible design.
Today, that journey takes its biggest step yet.
We're proud to introduce Collective Core™ – our own premium PET material platform and the foundation of a new generation of architectural acoustic products.
Developed over the past 12 months, Collective Core™ has been designed around the things that matter most to today's commercial interiors: outstanding acoustic performance, carefully considered colour, lower embodied carbon and, above all, complete confidence in specification.
Fire Performance Without Compromise
When developing Collective Core™, we wanted to go beyond simply achieving a fire classification.
Recent changes to UK Building Regulations have placed greater emphasis on understanding how products perform in real-world applications, not just in isolation.
That's why Collective Core™ has been independently tested across a wide range of installation methods, including:
• Adhesive-fixed applications
• Vertical and horizontal joints
• Air gaps
• Ceiling installations
These scenarios form part of the product's Field of Application, giving architects, designers and contractors greater confidence that the certification reflects how the product will actually be installed.
Because specifying with confidence starts with knowing exactly what has been tested.
One Platform. Four Collections.
From this single material platform comes four distinct collections, each offering a different design expression while sharing the same performance, colour palette and technical credentials.
Collective Core™ - Premium acoustic panels available in 35 carefully curated colours.

Collective Core Form™ - Embossed and moulded acoustic surfaces that bring texture, depth and architectural character.

Collective Core Cut™ - Precision-cut patterns that introduce graphic detail and visual rhythm.

Collective Core Print™ - Curated printed finishes, alongside bespoke designs developed with Collective Studio.

Together, these collections create a coordinated family of products, giving designers the freedom to create cohesive interiors through colour, material and performance.
Collective Core™ also represents an important milestone for The Collective. It reflects our continued evolution from distributor to designer and manufacturer, giving us greater control over quality, innovation and sustainability while creating better outcomes for architects, designers and contractors alike.
This is only the beginning.
Over the coming weeks, we'll be sharing more about the thinking behind Collective Core™, from our carefully curated colour palette and extended neutrals to the design philosophy behind Form, Core Cut and Print, and how the entire system has been developed to work seamlessly with Collective Cast™ and Collective RailLock™.
One material. Four collections. Designed to work together.
