100mm Knauf Earthwool Acoustic Insulation Roll

The 100mm 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 100mm glass mineral wool roll provides outstanding sound absorption and effective noise reduction.

One key advantage of the 100mm Knauf APR Sound Insulation Roll is its straightforward installation—considerably simpler than rigid alternatives like PIR boards. The material is completely odour-free, resists rot, and won't attract vermin. It naturally resists fungi, mould, and bacterial growth.

The 100mm Earthwool Acoustic Insulation Rolls conform perfectly to uneven surfaces and bond together seamlessly, preventing air gaps (thermal bridging). This quality is essential for achieving reliable performance across different applications.

Purpose-built for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls, 100mm Knauf Insulation Roll boosts both acoustic and thermal performance. When used as a sound absorbent layer in partitions and floors, it substantially improves acoustic qualities, tackling the hollow sound that often occurs in empty partition cavities.

Benefits

Independent testing with major Knauf plasterboard products confirms reliable compliance with acoustic building regulations. With a density exceeding 10kg/m³, the 100mm Knauf Acoustic Roll meets the requirements of relevant acoustic building standards.

Positioned between studs, these rolls seal joints effectively, reducing unwanted gaps and delivering superior sound insulation performance. The pre-cut lengths make installation quick and hassle-free.

Application:

The 100mm Knauf Acoustic Roll fits snugly 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 100mm Acoustic Roll also works as a friction fit between resilient timber battens and timber studs in Robust Detail separating floors and walls.

Beyond sound absorption, the 100mm Knauf APR Roll strengthens thermal and fire performance in walls, floors, or partitions. Glass Mineral Wool functions as an effective sound absorbent in partitions and floor acoustic insulation, significantly enhancing acoustic properties. In internal walls, Glass Mineral Wool works alongside plasterboard to absorb airborne sound, reduce echo, and eliminate the hollow effect typical of unfilled partition cavities.

Durability

100mm Acoustic Partition Insulation Roll is odourless, rot proof, non-hygroscopic, resists vermin, and will not support fungi, mould or bacteria growth.

Real Performance

Glass and Rock Mineral Wool Insulation installs more easily than rigid alternatives such as boards because it flexes to fit substrate irregularities and bonds together, closing any air gaps. Research confirms that eliminating air gaps is vital for achieving genuine performance in the relevant application.
