25mm Knauf Earthwool Acoustic Insulation Roll

The 25mm 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 25mm glass mineral wool roll provides excellent sound absorption and effective noise reduction.

The 25mm Knauf APR Sound Insulation Roll stands out for being twice as straightforward to fit correctly than alternative materials such as PIR boards. It's completely odour-free, resistant to rot, and won't attract vermin. The material naturally resists fungi, mould, and bacterial growth.

Thanks to its flexibility and ability to conform to surface variations, the 25mm Earthwool Acoustic Insulation Rolls seal gaps seamlessly and prevent thermal bridging. This quality is essential for delivering reliable performance across different applications.

Engineered for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls, 25mm Knauf Insulation Roll improves both acoustic and thermal qualities. When used as a sound-absorbing layer in partitions and floors, it substantially boosts acoustic performance and eliminates the hollow resonance typical of empty partition cavities.

Benefits

Testing results from leading Knauf plasterboard products demonstrate reliable compliance with acoustic building regulations. With a manufacturing density exceeding 10kg/m³, the 25mm Knauf Acoustic Roll meets the requirements of relevant sound-related building standards.

Positioned between studs, these rolls create tight seals at joints, reducing unwanted gaps and delivering superior sound insulation performance. The extended pre-cut roll lengths make installation quick and hassle-free.

Application:

The 25mm Knauf Acoustic Roll fits snugly between joists and studs at 400mm and 600mm centres, boosting sound insulation in these areas:

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

The 25mm 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 25mm Knauf APR Roll strengthens the thermal and fire performance of walls, floors, or partitions. Glass Mineral Wool functions as an effective sound-absorbing layer in partitions and floor acoustic insulation, significantly enhancing acoustic capabilities. In internal walls, Glass Mineral Wool works alongside plasterboard to absorb airborne noise, reduce echo, and effectively prevent the hollow sound common in empty partition cavities.

Durability

25mm Acoustic Partition Insulation Roll is odourless, rot proof, non-hygroscopic, resists vermin, and won't support the development of fungi, mould or bacteria.

Real Performance

Glass and Rock Mineral Wool Insulation are simpler to install correctly than rigid board alternatives because they flex to match substrate irregularities and bond together, preventing air gaps. Research confirms that eliminating air gaps is vital for achieving genuine performance in your application.
