Product Description

Keep a little zen in your home with Knauf Acoustic Partition Rolls (APR). 75mm Earthwool Acoustic Roll is manufactured using glass mineral wool and Knauf Insulation's unique bio-based binder, ECOSE® Technology. This makes it soft to the touch and a dream to both handle and install. The rolls offer enhanced acoustic performance and superb noise reduction properties in both new and refurb internal wall and separating floor applications.

The 1200mm width rolls are manufactured to a minimum density of 10Kg/m3 and feature perforations to create 2 x 600mm rolls, saving you time and guaranteeing a concise cut. Rolls are designed to fit between studs to close joints, reducing the potential for unwanted gaps and ensuring high levels of sound insulation. They also achieve an impressive fire rating of A1 non-combustible.

75mm Earthwool Acoustic Sound Insulation Roll Applications

Knauf insulation acoustic roll is a champion sound absorber; it is particularly effective at preventing hollow sound that can occur in partitions with unfilled cavities. Earthwool Acoustic Roll is specifically designed for friction fitting between resilient timber battens and timber studs in robust detail separating floors and walls at 600mm centres. 

It works to reduce noise transmission and ensure continuity of the absorbent layer with no air gaps, whilst also bumping up the thermal and fire performance of walls, floors and partitions.

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)

75mm Earthwool Acoustic Sound Insulation Specifications

Thanks to 75mm Earthwool Knauf acoustic roll's open-fibre structure, the rolls are able to latch onto sound as it passes through, reducing noise transfer from room to room.

75mm 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
  • Odourless, rot proof and non-hygroscopic
  • Roll format and long roll lengths 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

Knauf Acoustic Roll 75mm Certifications

  • Generic BRE Green Guide Rating A+
  • Classified as Zero ODP (Ozone Depletion Potential) and Zero GWP (Global Warming Potential)
  • A1 Euroclass Fire Rating
  • Manufactured in accordance with BS EN 13162
  • Awarded the DECLARE `Red List Free’ label - meaning no 'Red List' ingredients, including formaldehyde or phenol

Handling & Storage Earthwool 75mm Insulation Roll

Earthwool acoustic roll is easy to both handle and install. Thanks to its lightweight composition, it is easily cut to size and moved around on site. 

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.

75mm Knauf Earthwool Acoustic Performance

Knauf Earthwool rolls are the perfect choice for people who want to insulate their homes against unwanted noise. Glass mineral wool roll is an excellent acoustic insulation solution because rock is a natural sound barrier. Due to its unique, non-directional structure, Knauf Earthwool is denser than conventional insulation and helps to absorb and minimise sound.

The rolls have a minimum manufactured density of 10kg/m3, and this manufactured density meets standards for robust detail walls and floors.

Great product with excellent thermal and fire performance. also does a good job of sound absorption. filled in all the air gaps in the loft and couldn't be more chuffed.
