75mm Knauf Earthwool Acoustic Insulation Roll

The 75mm Knauf Earthwool APR Acoustic Insulation Roll is a dependable choice for managing sound in internal walls, partitions, and floors. Built using ECOSE Technology, this non-combustible 75mm glass mineral wool roll provides outstanding sound absorption and noise reduction capabilities.

What sets the 75mm Knauf APR Sound Insulation Roll apart is how straightforward it is to fit correctly—twice as simple as working with rigid PIR boards. It's completely odour-free, resists rot, and won't attract vermin. The material won't support the development of fungi, mould, or bacteria.

Thanks to their flexibility, the 75mm Earthwool Acoustic Insulation Rolls conform beautifully to substrate irregularities and fit together seamlessly, preventing air gaps (thermal bridging). This quality is essential for achieving the performance you need across different applications.

Engineered specifically for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls, 75mm Knauf Insulation Roll boosts both acoustic and thermal performance. When used as a sound absorbent layer in partitions and floors, it dramatically improves acoustic performance and tackles the hollow sound that often crops up in unfilled partition cavities.

Benefits

Testing results with leading Knauf plasterboard products confirm reliable compliance with sound-related building regulations. The 75mm Knauf Acoustic Roll achieves a manufacturing density above 10kg/m³, meeting the requirements set out in relevant sound-related building regulations.

These rolls fit snugly between studs and effectively seal joints, reducing the chance of unwanted gaps and delivering superior sound insulation. The pre-cut lengths make installation quick and hassle-free.

Application:

The 75mm Knauf Acoustic Roll is designed to fit neatly between joists and studs at 400mm and 600mm centres, delivering sound insulation for:

• Separating walls and floors
• Internal walls and floors
• Timber and metal stud partitions

The 75mm Acoustic Roll also works brilliantly for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls.

Beyond excellent sound absorption, the 75mm Knauf APR Roll enhances thermal and fire performance in walls, floors, and partitions. Glass Mineral Wool as a sound absorbent layer in partitions and floor acoustic insulation significantly boosts acoustic capabilities. In internal walls, Glass Mineral Wool works alongside plasterboard linings to absorb airborne sound, reduce reverberation, and prevent the hollow sound typical of empty partition cavities.

Durability

75mm Acoustic Partition Insulation Roll is odourless, rot proof, non-hygroscopic, doesn't attract vermin, and won't support fungi, mould, or bacterial growth.

Real Performance

Glass and Rock Mineral Wool Insulation is simpler to install correctly than rigid boards because it adapts to minor substrate imperfections and bonds together, eliminating air gaps. Research demonstrates that avoiding air gaps is vital for achieving genuine performance in your application.
