Acoustic and Thermal Composite Barriers

At LOCK5 we've always believed that the details nobody notices are the ones that matter most. The room that holds its temperature all evening. The spaces that stay acoustically separate. The build that performs as beautifully as it looks.

Which is why we're proud to offer our Acoustic and Thermal Composite Barrier, a lining solution engineered to make event spaces perform as beautifully as they appear effortless.

What it does

Our composite barrier manages two of the most important elements of any temporary event space: sound and temperature.

Installed as part of our wall or roof lining system, it reduces heat loss, improves energy efficiency and provides meaningful acoustic insulation between spaces, whether that's a conference room that needs privacy, a live music environment that needs control, or a long-term installation where comfort is non-negotiable.

It can be installed vertically, horizontally or on a pitch, enhanced with additional layers where performance demands are higher, and integrated seamlessly into any interior design. It disappears into the space and lets everything else shine.

Why it matters

Guests feel temperature. They feel acoustic separation. They feel the difference between a space that has been thought through completely and one that hasn't.

Our composite barrier is how we make sure every LOCK5 event space is thought through completely.

The detail

Quick to install, reducing labour costs and minimising disruption on tight timelines. 100% reusable, avoiding landfill and supporting our commitment to sustainable practice. Flame-resistant core, meeting UK safety standards as standard. Available in black or white, with RAL colours available on request.

The LOCK5 standard

We include everything a project actually needs. That includes the elements nobody sees on the night but that every guest feels from the moment they walk in.
