Isover Acoustic Partition Roll
Isover’s Acoustic Partition Roll (APR) is installed inside the hollow space of a stud wall or between the joists in a floor. It is used as part of a full wall or floor system to reduce sound transmission so rooms stay quieter.
What is isover acoustic insulation roll?
Isover Acoustic Insulation Roll is a long roll of glass mineral wool fixed between studs or joists. Its fibrous structure traps and disperses sound waves to minimise sound transmission. It also provides thermal resistance, supporting sound control, and providing modest thermal insulation.
What is isover acoustic roll used for?
Isover Acoustic Roll is used:
- Inside partition walls
- Within timber or metal stud partition systems
- Between joists in separating floors
Install it so it friction-fits between studs (it is commonly supplied in 600mm and 1200mm widths to match stud centres).
Benefits of isover APR
Acoustic Isover partition roll insulation is beneficial in these ways:
- Quieter rooms: The fibres absorb sound, reducing voices and footsteps. But it does not entirely block noise on its own.
- Easy to fit: Supplied in widths to slip into standard stud spacings for quick friction-fit installation.
- Fire performance: Non-combustible Euroclass A1 material. Does not contribute to the spread of fire.
- Offers additional thermal performance: Provides modest thermal performance due to its thermal conductivity of glass mineral wool.

How to cut Isover acoustic insulation?
- Measure the distance between two joists or studs.
- Unroll a small portion of the Isover acoustic roll. Measure a portion of the same size as the joist-to-joist measurement you took, and mark where to cut.
- Cut across the marked line using a sharp insulation knife (or shears with a long blade).
- Friction-fit the piece into the space to ensure a tight fit.
Use protective gloves, eye protection, and a dust mask while cutting.
Does isover acoustic partition roll block sound?
No, APR does not fully block sound as a solid wall does, but it absorbs and weakens any sound that passes through the cavity. It reduces airborne noise and helps improve the overall sound insulation of the wall or floor assembly when combined with the right boards and construction details. For required acoustic ratings (e.g., Part E in England & Wales or Section 5 in Scotland), you must build the correct wall system – the APR is a key part of that system, not the whole system by itself.
