Acoustic insulation: What can it do for you?

Acoustic insulation is becoming more popular as urban areas become more dense and family homes become more compact. Families want to retain peace and privacy from room to room as well as from the outside in.

Keeping everybody happy

The development of surround sound and 4K televisions has made watching movies at home a more cinema-like experience. Did you know that installing acoustic insulation could mean a better cinema experience? Natural acoustic insulation such as sheep’s wool absorbs sound that it’s exposed to, reducing echo and improving overall acoustic quality. Sound is also dampened in surrounding rooms seeing as the bulk of noise is absorbed. If you combine this with a denser, heavyweight acoustic product such as Knauf plasterboard, the neighbours won’t be susceptible to the latest theatrical release, and neither will family members who didn’t want to be in on the action!

On the right side of the law

In the UK there are several guidelines pertaining to noise pollution thanks to the Environment Protection Act 1997. These guidelines set out what levels of sound you’re allowed to emit dependent on what ‘zone’ a building is designated in. Between 10pm and 7am Monday – Saturday for example, residential areas can emit a maximum noise level of 35 decibels (dB). Acoustic insulation can help in two ways. The first is that thanks to installing dense insulation there won’t be as much noise emitted as before. So if you’re playing music after 11pm you’ll be able to play it louder, thanks to the decibel reduction that acoustic insulation will afford you. During the day (defined as 7am to 10pm Monday – Saturday) for residential areas that decibel allowance only rises by 10.

acousticThe second way sound insulation will help is by keeping the noise of others out. Industrial areas, city areas and recreation areas have a higher night-time decibel allowance, meaning you’re more likely to be disturbed by external sounds. By insulating acoustically you’ll keep this noise out so city pubs, industrial plants and transports links such as planes and trains will all appear to be quieter.

How dense do you need acoustic insulation?

Density matters in acoustic insulation as the thickness and density combined will determine how effective the insulation is. Low-density acoustic insulation prevents echoes and reduces noise in places such as office buildings for example. To achieve soundproofing in this scenario you’d need more dense insulation or many layers of low-density insulation.

In a project where acoustic insulation is required about the house, a low-density acoustic insulation product suits as there’s less noise to combat so you won’t need lots of thickness. If you are trying to combat loud noises such as a drum set, opt for a thinner, high-density product to minimise costs and save floor space from thinner walls.

Naturally acoustic

Natural products such as stone wool and sheep wool all have great acoustically-insulating factors. As well as being sustainable and good for the environment, these types of insulation can be the perfect solution for acoustically insulating a home.

What can acoustic insulation do for you?

Whether you or your customer is looking for some respite from a child’s drum set, noisy neighbours, or a surround-sound cinema experience in the living room, acoustic insulation can upgrade your quality of life.
