Sustainable by design
At The Collective, we take a considered approach to how materials are sourced, made and used, focusing on long-term responsibility rather than short-term claims.
Collective RailLock™ uses Collective Core™ acoustic PET which is a low carbon, low VOC product, manufactured in a low carbon facility as part of our wider commitment to reducing environmental impact. Our zero-waste manufacturing initiative ensures material is used efficiently, with offcuts redirected into new products wherever possible.
We work with a carefully managed supply chain, with clear policies in place under our ISO14001 to ensure ethical sourcing and to prevent modern slavery.
Collective RailLock™ also supports sustainable building standards, with a Lifecycle Assessment (LCA) contributing towards WELL, LEED, Green Star and BREEAM certification.




SCULPTURAL DESIGN. ENGINEERED TO PERFORM.
Collective RailLock™ Sails introduce architectural form and acoustic performance into open ceiling environments, creating suspended features that define spaces while improving acoustic comfort.
