How to Soundproof Your Garage

Garage Doors , House , Tips and Troubleshooting   Brett Rowley  | 23 October 2019

The garage is a great place to carry out hobbies such as band practice, carpentry and working on your car.

It’s a secluded area away from everything else allowing you to really focus on honing your skills.

As much as you love tinkering away in your garage workshop or banging the drums, your wife or neighbours seem to strongly disapprove. 

It might be tolerable if it was once a week at a decent hour of the day, but what if it’s 5 times a week, morning and night?

There are two options:

  • A: continue as it is and risk your neighbours making an official complaint, or, 
  • B: soundproof your garage and keep everyone happy.

We’re going to assume you went with option B. 

To help you continue to do what you love, here are some tips and tricks to soundproof your garage.

Types of noise

Before you start soundproofing, you’ll first need to consider two types of noises.

Airborne noises

are noises that come from common sound sources such as talking, televisions and radios. Your home’s noise performance is determined by Sound Transmission Class (STC), the higher the STC the more noise is nullified. 

Sound bounces off hard surfaces and is amplified, so you can imagine how loud something can be inside your garage, considering it’s encompassed in hard surfaces; floors, walls and metal. 

Impact noises

Are produced by noises that pass through the structure to create noises in nearby rooms. Examples of impact noises include heavy footsteps, doors closing, scraping furniture, and vibrations from music or power tools.

How to soundproof your garage

1. Install insulation

One of the easiest ways to soundproof your garage is to insulate. Not only does it provide an R-value to effectively reduce heat loss and heat gain, but it can also increase STC and effectively reduce outside noises by up to 4-6 dB. 

There are various types of insulation available, including cellulose insulation, fibreglass, and spray foam. There are multiple areas of consideration when insulating and include your garage ceiling, garage concrete floors, garage walls and your garage door.

Garage door insulation panels provide a thermal value of R1.47, effectively reducing heat loss and heat gain, giving you a more energy-efficient home and lower energy bills. All of our panels are Australian made by ThermaDoor and come with a reflective foil backing and exclusive white vinyl finish of the panels, fire retardant – perfect for homes that are located near fire-prone bushland.

ThermaDoor Insulation panels in the garage provide an additional sound barrier, significantly reducing outside noise and giving you much needed peace and quiet for a good night’s rest.

All panels can be retro-fitted and customised to suit any door, is impact resilient and lightweight.

Thermadoor panels can be fitted on sectional and custom-made garage doors. 

But they also provide an additional sound barrier, significantly reducing outside noise and giving your wife and neighbours much needed peace and quiet.

2. Install acoustic foam panels

They don’t seem like much at first, but acoustic foam panels can improve the sound insulation of any room, including your garage. Foam panels help with reducing impact noises by adding a soft layer to hard surfaces, preventing the sound from bouncing and vibrating. 

Consider adding acoustic foam panels to the walls and ceilings inside your garage, and if you aren’t phased about the view, you can place them on windows as well. It is important to remember that they can collect dust very easily, so it would be in your best interest to clean them regularly.

3. Lay down rubber mats

As mentioned before, insulating your garage flooring can be another excellent way of soundproofing your garage. Hard surfaces amplify impact noises, giving them an area to bounce and vibrate off, however, this can be easily prevented by laying down some rubber mats. 

Although rubber mats may not be necessarily ‘soundproof’, they help minimise sound vibrations. Old carpet is another option to consider, you simply just need to put something soft over the surface that will absorb some of the noise.

4. Use acoustic blankets and sheets

Acoustic blankets and sheets are one of the easiest and most cost-effective methods you need to try first. They are highly flexible and can be placed on a moving door with sound absorption levels of up to 50%. 

Consider hanging them from the ceiling all the way down to your floor using hanging rods or hooks to prevent sound from going through. This is where the term, creating a ‘room inside a room’ comes from, whereby you create an enclosed area using acoustic blankets to prevent sound from travelling through the walls.
