25mm Knauf Acoustic (APR) Insulation Roll (26.64m2/Roll)

What Is 25mm Knauf Acoustic Roll? 

Knauf Acoustic 25mm Insulation Roll excels in sound absorption and concurrently enhances the thermal and fire resistance of walls, floors, and partitions. 

Specifically engineered for friction fitting between joists and studs at 600mm centres, Acoustic Roll effectively reduces noise transmission across separating walls and floors, as well as in internal structures and both timber and metal stud partitions.

Constructed from glass mineral wool fibres and unified by Knauf Insulation's advanced ECOSE Technology, these 25mm insulation rolls offer a softer texture and an improved handling experience.

Measuring 1200mm in width, they are produced with a minimum density of 10Kg/m3 and are designed with perforations that allow for division into four 600mm sections. Additionally, they boast a high fire safety rating of A1, classifying them as non-combustible.

25mm Acoustic Sound Insulation Roll Applications

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

25mm Knauf Acoustic Performance

25mm acoustic rolls are made from robust glass mineral wool. The glass wool manufacturing process creates a product with a random fibre structure which traps thousands of air pockets; these air pockets essentially 'catch' the sound as it passes through, reducing noise transmission. 

Sound waves travel through materials in vibrations. If your walls and floors are not insulated, there are very few barriers for the sound waves to get through. The more layers the vibrations have to travel through, the fewer that will make it into the next room. The rolls have a minimum density of 10kg/m3, and this manufactured density meets standards for robust detail separating floors and walls.
