100mm Knauf Earthwool Acoustic Insulation Roll

The 100mm Knauf Earthwool APR Acoustic Insulation Roll is a dependable choice for controlling sound in internal walls, partitions, and floors. Built with ECOSE Technology, this non-combustible glass mineral wool roll provides outstanding sound absorption and effective noise reduction.

The 100mm Knauf APR Sound Insulation Roll installs twice as quickly as rigid alternatives like PIR boards. Completely odour-free, rot-resistant, and impervious to pest damage, these rolls resist fungal, mould, and bacterial growth.

100mm Earthwool Acoustic Insulation Rolls conform perfectly to substrate irregularities and bond seamlessly, preventing air gaps that cause thermal bridging. This quality is essential for achieving superior performance across multiple 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. As a sound-absorbing layer in partitions and floors, it dramatically improves acoustic quality, eliminating the hollow resonance typical of empty partition cavities.

Benefits

Rigorous testing with leading Knauf plasterboard products confirms compliance with acoustic building regulations. With a density exceeding 10kg/m³, the 100mm Knauf Acoustic Roll meets all relevant sound-control building code requirements.

Positioned between studs, these rolls seal joints effectively, preventing unwanted gaps and delivering superior sound insulation performance. The extended pre-cut roll lengths enable fast, hassle-free installation.

Application:

The 100mm Knauf Acoustic Roll fits snugly between joists and studs spaced at 400mm and 600mm intervals, delivering sound insulation for:

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

The 100mm Acoustic Roll also friction-fits 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, and partitions. Glass Mineral Wool as a sound-absorbing layer in partitions and floor acoustic insulation substantially enhances acoustic capabilities. In internal walls, Glass Mineral Wool works alongside plasterboard to absorb airborne sound, reduce reverberation, and prevent the hollow sound common in unfilled partition cavities.

Durability

100mm Acoustic Partition Insulation Roll is odourless, rot-proof, non-hygroscopic, resists vermin, and prevents fungal, mould, and bacterial growth.

Real Performance

Glass and Rock Mineral Wool Insulation installs more reliably than rigid boards such as PIR because it flexes to accommodate substrate imperfections and bonds together, eliminating air gaps. Research confirms that eliminating air gaps is critical for achieving genuine performance in the relevant application.
