CASE STUDY: ISOVER
When do noisy neighbours become noise pollution? BMJ caught up with Isover senior product manager Stuart Dumbarton to understand the issue of noise within homes and how it can be combatted when building new homes.
A
s the nation’s lifestyles become more hectic, the idea of going home to have a cup of tea in silence is an attractive proposition. But unfortunately, due to the acoustics of some properties this can only be a dream.
According to Saint-Gobain’s UK Home, Health and Wellbeing Report, around 90 per cent of most people’s time is spent indoors, with 65 per cent of this at home. Stuart Dumbarton, senior product manager at Isover says: “With this in mind, you can understand why so much emphasis is now being placed on how buildings affect the occupants’ health and well-being, However, one of the key concerns is noise within buildings and how poor acoustics can seriously impact those using or living in the space.”
Recognising this, Dumbarton says that Isover has launched the Sound Good Factor campaign to raise awareness of good acoustics within the UK construction industry.
“Just how serious is the issue of noise pollution?” he asks. “There are many factors of a building that can negatively impact occupants’ comfort, but noise is one of the most prevalent. It can impact human health when it interferes with people’s daily activities at school, work and home. Excessive noise can disturb sleep, cause cardiovascular and psychophysiological effects, reduce performance and provoke annoyance responses and changes in social behaviour . And unfortunately, people will always be subjected to noise in their homes – whether they live in a busy city, quiet suburb or even in the middle of the countryside, due to noise from neighbours, high trafficked roads or noise from family living within homes. “
Taking the above into consideration, Dumbarton says that
housebuilders are now starting to recognise the importance of reducing unwanted noise within homes, in order to ensure that a comfortable environment is created for future residents.
“One of the easiest ways to tackle the transfer of noise between adjoining properties and internal rooms and floors is the installation of glass mineral wool insulation,” he continues. “Glass mineral wool offers

great benefits over other insulation materials available; it is lightweight, easy to install, non-combustible, sustainable and provides effective thermal and acoustic performance. It is also extremely versatile, being manufactured in both roll and slab form, making it suitable for a wide range of applications.
“At Isover we offer a range of specialist glass mineral wool acoustic insulation, which effectively dampens sound and reduces its transfer across walls and floors. For example, for separating walls, Isover’s RD Party Wall Roll is a key component of many Robust Detail specifications and can offer a sound reduction of at least 5 dB better than that required by the Building Regulations, while still providing the best possible level of thermal performance.”
Dumbarton says that the best option for internal walls is a lightweight partition (either timber or metal stud), consisting of two sheets of plasterboard with a layer of glass mineral wool, sandwiched in-between. “And for internal floors, our Acoustic Partition Roll 1200 is also specified to enhance sound absorption within the floor/ceiling void in order to achieve the minimum airborne sound insulation performance required by building regulations.”
ensuring that their builder customers are up to speed wit the best option for reducing noise pollution in their builds. “When it comes to helping housebuilders – large, small or medium – it is vital that merchants understand the products available on the market, which can help their customers to build properties to a higher standard,” he says. “By liaising with a manufacturer such as Isover, we can provide technical guidance on products and their applications, which in turn can be used by the merchant to help advise customers. What’s more, if merchants sell our acoustic solutions as part of British Gypsum’s drywall systems, it will be covered by the British Gypsum SpecSure® warranty, which will provide peace of mind to the British Gypsum SpecSure® warranty, which will provide peace of mind to the customer that the insulation installed has lifetime performance guaranteed.” BMJ
