Acoustic insulation for trade and individual buyers

In our experience, acoustic performance issues on site usually come back to an undersized or wrongly specified product. The right acoustic insulation slab or board, correctly specified for the build-up, will meet Part E requirements and reduce on-site remediation later.

We supply acoustic insulation for walls, partitions and floor systems to contractors and individual buyers who need dependable materials prepared to their requirements. Trade pricing is available across our key ranges, with stock held in depth for quick turnaround. Our cut-to-size service, available from our West Sussex and Hampshire depots, means acoustic insulation arrives ready to install, reducing waste and keeping your programme on track.

What to consider when specifying acoustic insulation materials? 

The right material depends on the application. Key factors include:

- Whether the priority is airborne sound, impact sound or both
- The available build-up depth within the partition or floor system
- Fire performance requirements alongside acoustic control
- Whether a friction-fit slab or a more rigid board suits the construction

For acoustic wall insulation in stud partitions and separating walls, high-density stone wool slabs are the most widely specified solution. Rockwool acoustic insulation is a non-combustible slab that fits cleanly between studs and delivers consistent sound absorption relevant to speech and general building noise.

If you are weighing up options, call us with the construction type and we will point you towards the right product and thickness for the job.

Acoustic performance and compliance

In the UK, acoustic performance in new build and conversion projects is governed by Part E of the Building Regulations, which sets minimum requirements for sound insulation between dwellings and rooms used for residential purposes. Meeting Part E typically requires demonstrating an adequate sound reduction index, measured in decibels (dB) and expressed as a weighted value (Rw), across separating walls and floor systems.

Airborne sound covers noise that travels through the air such as voices and music. Impact sound covers noise generated by physical contact with the structure, such as footsteps. Most partition and floor specifications need to address both, though the dominant concern varies by application.

Getting the density and thickness right for your build-up is usually the straightforward part - where specifications catch people out is flanking sound, noise that travels indirectly through connected structural elements rather than directly through the partition. If that is a concern on your project, it is worth discussing continuity of insulation at junctions before materials are ordered.

Our team can advise on suitable build-ups for Part E compliance and help you select acoustic insulation materials that meet your performance targets without unnecessary cost or added depth.

Acoustic insulation rolls and slabs

Acoustic insulation is available in slab and roll formats depending on the application. Acoustic insulation slabs are typically the preferred choice for wall and partition builds, where rigidity and a consistent friction fit between studs or battens is important. Acoustic insulation roll formats tend to suit floor and ceiling applications where coverage over larger areas is the priority.

If you are not sure which format is right for your job, give us a call and we will sort it out quickly.
