75mm APR Knauf Earthwool Acoustic Insulation Roll is a non-combustible glass mineral wool acoustic insulation roll which offers high level of sound absorption and noise reduction in internal wall, partitions and floor applications.

Sound Insulation Roll 75mm is manufactured using Knauf ECOSE Technology and is 2 times easier to install correctly than other insulation materials such as PIR boards.

Acoustic Rolls are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Earthwool Acoustic Insulation Rolls adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps (thermal bridging).

The absence of air gaps is crucial to achieving a high level of performance in the relevant application.

Knauf APR Roll is also designed for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls.

Sound Insulation provides a high level of sound absorption, whilst also improving the thermal and fire performance of the floor, wall or partitions.

Using Knauf Acoustic Roll as a sound absorbent layer in partitions and floors significantly improves their acoustic performance.

Acoustic Roll is particularly effective at preventing the hollow sound that can occur in partitions with unfilled cavities.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
