Acoustic Insulation
Help reduce the movement of sound through walls, floors and ceilings with acoustic insulation
Controlling how sound moves through a residential building or commercial property can help to improve wellbeing and comfort for those inside. Isover insulation can contribute to acoustic performance in applications from partition and party walls to metal and timber framed walls, as well as cladding.

The benefits of acoustic insulation
Whether it’s for commercial or residential applications, mineral wool insulation with acoustic properties can help reduce sound transmission between adjoining spaces when used in a well-designed system. Let’s look at the core elements.
The non-continuous structure of the glass fibres that make up glass mineral wool impede the passage of sound. This can be used in systems to reduce airborne sound transmission and improve acoustic insulation when installed in accordance with the manufacturer’s system installation guidance. For our system information, please refer to the British Gypsum White Book specification selector.
The tightly packed fibres in mineral wool helps to absorb sound energy and low-frequency sounds, ideal for noisy places such as multioccupancy flats, busy public spaces and schools.
By reducing the movement of noise through walls, floors and ceilings, acoustic insulation can help create a more comfortable environment for occupants.

Frequently Asked Questions
I have severe allergies, and my contractor is installing Isover. What’s in the product?
We are unable to provide specific case advice – however, please refer to our Safe Use Instruction Sheet (SUIS), a link to which you’ll find below. Our product contains less than 1% mineral oil, which is added to reduce dusting of the glass mineral wool.
For more details, please read are SUIS Sheet here
Does your insulation contain palm oil?
No. Isover insulation does not contain palm oil.
Is Isover packaging recyclable?
Yes. In 2025, we also reduced the ink coverage in our white packaging to less than 15%. This reduction means our packaging can now be used to produce a wider variety of items made of recycled content than previously. This is because using a higher proportion of white plastic makes it more versatile. Our packaging also contains 30% Post Consumer Recycled content, which means less raw virgin materials go into our packaging and further strengthens our commitment to sustainability.
Do you recycle leftover insulation?
Isover doesn’t currently offer a customer recycling service. If you do need to dispose of leftover insulation, residues or by-products, this should comply with the requirements of environmental and waste disposal legislation and any local authority rules.
