Soundproofing: How Acoustic Insulation Works

The effect of noise on our lives can be reduced with thoughtful design and practice, thus improving the quality of the living environment.
Soundproofing: How Acoustic Insulation Works

You don’t have to put up with excess noise in your home.

There are many affordable ways you can minimise the racket coming from your teenager’s bedroom, or make that lockdown-ready movie room more atmospheric. The answer lies in soundproofing.

The Benefits Of Acoustic Insulation

Noise is greatly reduced between rooms and buildings thanks to acoustic insulation. Whatever the reason, acoustic insulation can help you live a less noisy life, whether it be pets, kids watching movies, or traffic outside.

Installing acoustic insulation is perfect for:

  • Home theatres
  • Home offices, study or parents’ retreats
  • Bathrooms and ensuites 
  • Laundries 
  • External walls 
  • Nursery/kids rooms

Acoustic insulation is an excellent solution for increasing the comfort of your home or the efficiency of your workplace by reducing noise transfer.

Acoustic Insulation can help reduce noise transfer between:

  • Internal rooms i.e. between a bedroom and bathroom or bedroom and living areas
  • Between the first and second floors in two-storey homes
  • Between apartments (in apartment living)
  • Between commercial properties (i.e. in shopping centres or office complexes)
  • Dampen environmental noise from busy roads or aircraft

In a multi-storey house, sound will travel between floors. Budget for soundproofing under the floor, especially if your sleeping areas are directly above your living or entertainment areas.

Ways To Soundproof A Room

It’s best – and cheaper – to plan your soundproofing during a new home build, but you can still soundproof an established home.

Insulation batts made from a mix of mineral wool, fibreglass and polyester, as well as blown-in cellulose fibre insulation are your best options for soundproofing. 

With the blown-in insulation, it’s pumped into existing walls and provides both thermal and acoustic ratings, with the added benefit of being fire and vermin resistant. 

Alternatively, ECO Home Insulation uses a range of quality acoustic batts that are best to install at the time of construction, or during a renovation.

In both cases, the materials provide excellent insulation, and reduce noise effectively.


Make acoustic insulation part of your soundproofing strategy. 

ECO Home Insulation can advise on different types of acoustic insulation. If we’re supplying and installing acoustic products, we are required to carry out a FREE site inspection and quote to ensure that the job can be successfully installed and account for any obstacles that may make the install more challenging.

Soundproofing vs Sound Absorbing

Insulation can reduce sound dramatically, but you will still hear some sounds through it.

If you want total soundproofing, you need to supplement the insulation with other procedures such as installing thicker doors, sealing off any gaps or cracks, using acoustic wall panels, hanging sound-dampening curtains, or laying thick carpet on the floor. 

For most people who simply want reduced noise, however, acoustic insulation will be more than enough.

FAQs

What sound transmission and insulation guidelines exist?

This non-mandatory Handbook (PDF) provides guidance to practitioners involved in design, construction, development, certification or approval implementation. It’s also intended for use in the review of solutions that provide acceptable levels of sound insulation for buildings.

Does soundproof paint really work?

Not super effectively, on its own. Soundproof paint does not actually block sound, but it does assist in absorbing sound. It can be helpful for reducing low background noise with enough coats, but insulation materials are more effective.

Do you know your home’s energy rating?

The majority of homes built pre-2000 seriously need insulation repair, top-up or, in some cases, removal and reinstallation. Without attention to this important issue, homeowners are definitely paying way more for heating and cooling than they could be. ECO Home Insulation is able to supply traditional low-cost fibreglass products or innovative products that increase the all-important energy rating of the new home or development. Houses built pre-2000 are likely to have a rating of around 1.5 stars. With ECO Home Insulation, you can make a plan for increasing your rating to 5 or 6 stars, giving you maximum benefit for your investment.
