Acoustic Insulation Roll
(8 Products)Acoustic insulation rolls attack noise at its source. Their dense mineral-wool fibres absorb airborne vibrations and disrupt the energy that would otherwise leak through a partition. Supplied in continuous lengths for quick placement between studs or joists, they deliver reliable sound reduction across homes, offices, and mixed-use buildings.

What Are Acoustic Insulation Rolls?
Acoustic insulation rolls look much like their thermal cousins, but they’re built for a different battle. Instead of fighting heat loss, these dense, springy mats wage war on noise.
Slipped into walls, floors, or ceilings, they soak up airborne sound before it can bounce around a room (or slip through to the neighbours), while also dampening the thrum that travels through joists and studs.
How They Work
- Soaks Up Sound: Sound waves entering a mineral-wool blanket encounter countless microscopic pathways. Each change of direction dissipates energy, and friction between fibres converts that energy into low-level heat. The result: airborne noise loses amplitude before it can penetrate the neighbouring space.
- Adds Weight, Cuts Vibration: The heavier the fill inside a cavity, the harder it is for sound to pass. High-density rolls add that heft, and because the fibres flex slightly, they also smother vibration that would otherwise travel through timber or steel.
- Kills the Echo Chamber: Empty studs and joists act like drums. Fill them to the brim and there’s no void left to resonate, so you stop that hollow, amplified sound at source.
Applications
- Stud partitions between homes, hotel rooms, or meeting suites
- Separating floors to tame airborne sound and soften footfall
- Suspended ceilings over open-plan offices
- Attics and pitched roofs to dull traffic noise in loft conversions
- Plant rooms and ducts to stop machinery hum spreading through the frame
Benefits
- A Quieter Home or Workspace: No more hearing the neighbours’ TV through the wall or footsteps echoing from upstairs. Acoustic rolls help soften everyday noise, making shared buildings more comfortable for everyone.
- Privacy Where It Matters: Whether it’s a late-night chat in the bedroom, a confidential board meeting, or a counselling session, the words stay right where they’re spoken, not drifting through plasterboard to whoever happens to be next door.
- Better Rest, Sharper Focus: With less background noise, people sleep more soundly and concentrate with fewer distractions.
- Meets The Regs: Rolls that meet Part E sound requirements help projects pass inspections the first time - saving time, stress, and potential rework.
- Adds Value Buyers Notice: Homes or offices advertised as “quiet” or “well-insulated” often stand out and command a stronger price.
Installation Tips
- Cut a shade oversize so the roll grips the studs without gaps.
- Seal every penetration (sockets, pipes, even hairline cracks) with acoustic mastic.
- Avoid crushing the fibre; a squashed roll loses both mass and air-pocket efficiency.
- Decouple where possible - consider using resilient bars or double studs.
Frequently Asked Acoustic Insulation Roll Questions
How Is The Effectiveness Of Acoustic Insulation Measured?
The effectiveness of acoustic insulation in reducing airborne sound is typically measured by its Sound Reduction Index (Rw), which quantifies how much sound it blocks.
For overall building elements (e.g., a wall), performance is assessed by the Weighted Sound Reduction Index (Rw) or DnT,w (element normalised level difference).
For materials, the Sound Absorption Coefficient (α) indicates how much sound energy it absorbs.
Is Acoustic Insulation Roll Effective Against All Types Of Noise?
Acoustic insulation roll is highly effective at reducing airborne noise, such as speech, music, and television sounds.
While it offers some contribution, its primary role is not in addressing impact noise (e.g., footsteps on a floor), which often requires additional measures like resilient layers or floating floor systems. For comprehensive noise control, a holistic acoustic design approach is necessary.
Where Is Acoustic Insulation Roll Typically Installed?
Acoustic insulation roll is commonly installed within the cavities of lightweight partition walls, between the joists of timber suspended floors, and within ceiling voids.
It is particularly effective in residential buildings, offices, and educational facilities where sound privacy and noise reduction are critical.
Can Acoustic Insulation Roll Be Installed In Existing Walls Or Floors?
Yes, acoustic insulation roll can be retrofitted into existing wall or floor cavities, though this usually requires opening up the structure (e.g., removing plasterboard or floorboards).
While more disruptive than installation during new construction, it can significantly improve the acoustic performance of an existing space.
