50mm Knauf Earthwool Acoustic Insulation Roll

The 50mm 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 50mm glass mineral wool roll provides excellent sound absorption and effective noise reduction.

The 50mm Knauf APR Sound Insulation Roll stands out for being twice as straightforward to fit correctly than alternative materials such as PIR boards. It's free from odours, won't rot, and resists vermin. The material doesn't support the development of fungi, mould, or bacteria.

Thanks to their flexibility and capacity to conform to substrate irregularities, the 50mm Earthwool Acoustic Insulation Rolls integrate seamlessly whilst eliminating air gaps (thermal bridging). This quality is essential for achieving peak performance across different applications.

Purpose-built for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls, 50mm Knauf Insulation Roll improves both acoustic and thermal performance. When applied as a sound-absorbing layer in partitions and floors, it substantially boosts acoustic performance, successfully reducing the hollow sound typical of empty partition cavities.

Benefits

Rigorous testing with leading Knauf plasterboard products confirms reliable compliance with acoustic building regulations. With a manufacturing density exceeding 10kg/m³, the 50mm Knauf Acoustic Roll meets the requirements set out in relevant acoustic building regulations.

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

Application:

The 50mm 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 50mm Acoustic Roll also works for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls.

Beyond sound absorption, the 50mm Knauf APR Roll enhances thermal and fire performance in walls, floors, or partitions. Glass Mineral Wool acts as an effective sound-absorbing layer in partitions and floor acoustic insulation, significantly improving acoustic capabilities. In internal walls, Glass Mineral Wool works alongside plasterboard to absorb airborne sound, reduce reverberation, and effectively eliminate the hollow sound found in unfilled partition cavities.

Durability

50mm Acoustic Partition Insulation Roll is odourless, rot-proof, non-hygroscopic, resists vermin, and won't support the growth of fungi, mould, or bacteria.

Real Performance

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