50mm Knauf Earthwool Acoustic (APR) Insulation Roll (16.2m2/Roll)

Invest in a little privacy with 50mm Knauf Acoustic Partition Rolls (APR). Made with glass mineral wool fibres and bound together using Knauf Insulation's innovative ECOSE Technology; these rolls promise a softer feel and a pleasant handling experience. 

Suitable for internal walls and separating floors, the 1200mm width rolls are manufactured to a minimum density of 10Kg/m3 and feature perforations to create 2 x 600mm rolls. They also achieve an impressive A1 Euroclass fire rating.

50mm Earthwool Acoustic Sound Insulation Roll Applications

Knauf insulation acoustic roll performs wonderfully as a sound absorber, whilst improving the thermal and fire performance of walls, floors and partitions. Earthwool Acoustic Roll is specifically designed for friction fitting between resilient timber battens and timber studs in separating floors and walls at 600mm centres to reduce noise transmission and ensure continuity of the absorbent layer with no air gaps.

Earthwool Knauf insulation acoustic roll can be used in the following residential building elements:

• Separating walls and floors
• Internal walls and floors
• Timber and metal stud partitions (including commercial metal stud partitions) 

50mm Earthwool Acoustic Sound Insulation Specifications

50mm Earthwool Knauf insulation acoustic roll is a robust glass mineral wool product featuring thousands of minuscule air pockets; these air pockets trap sound as it passes through, muffling noise and thus reducing noise transmission. 

50mm Knauf acoustic rolls are pre-perforated for 2 x 600mm rolls to allow quick and economic installation between standard timber studs and the joists of internal floors. Acoustic partition roll (APR) can be used in both wall and floor applications to reduce the passage of sound transmission through a wall or floor construction.

Let's have a look at the specs:

• Excellent sound absorption characteristics provide high levels of sound reduction
• Friction fits between studs and closes joints to ensure sound insulation performance is achieved
• Roll format allows quick installation
• Ready-cut rolls for use with timber studs at 600mm centres
• Euroclass Reaction to Fire Classification (A1-F): A1
• Proven test results with all major brands of plasterboard to provide assured compliance with sound related building regulations

Handling & Storage of Earthwool 50mm Insulation Roll 

Earthwool Acoustic Roll is easy to handle and install, being lightweight and easily cut to size. It is supplied in polythene packs which are designed for short term protection only. When it comes to storage, we advise that you store the slabs inside; keeping them nice and dry.

50mm Knauf Earthwool Acoustic Performance

The fibre matrix of Knauf Earthwool rolls encourages the absorption of sound waves, converting them into heat energy, whereas other insulation types simply let the sound pass through. 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 walls and floors.
