Pros
- More than 45 years of experience
- Works in residential, commercial, and industrial properties
- Pleasant to deal with from start to finish
- Also provides heat insulation services
Cons
- Untidy work
- Packed schedule, may take a while to visit your property
Cosywrap is at the top of my list because they’re one of the most experienced soundproofers in Adelaide, with over 45 years of experience installing thermal and acoustic solutions.
What’s even better is that they have worked on numerous projects in residential, commercial, and industrial properties. I checked their portfolio and was extremely impressed with the flexibility of their services.
I had a conversation with a landlord who had a positive experience with Cosywrap. She praised their pleasant demeanor throughout the process, from the initial contact to the installation.
She was particularly impressed with their ability to soundproof all parts of a room, from the walls to the windows. The company uses industry-standard products like Soundblock and Barrierboard, which are known for being effective and long-lasting.
I had the pleasure of visiting one of the properties they worked on, and I can confidently vouch for the quality of their soundproofing. There was a noticeable difference in the noise levels inside the rooms compared to outside.
What’s more, they also provide other valuable services that can be paired with soundproofing, such as heat insulation.
However, I did come across a minor downside mentioned by some clients. They complained about the slipshod clean-up after the installation.
For instance, one client mentioned finding leftover materials in her room.
Another thing to keep in mind is that because they have a high number of clients to attend to, you may not receive quick service.

Pros
- Great features for soundproofing materials (such as UV protection and moisture resistance)
- Professional team
- Simple and unobtrusive designs
Cons
- Takes some time to respond to website inquiries
- Small team
One of the great things about The Silencer is their dedication to high quality, which is evident in the efficiency of their products.
I checked their data sheets and saw that most of their materials have excellent features like moisture resistance, UV resistance, and eco-friendliness.
Moreover, they’ve worked with many offices and movie theaters that require top-notch soundproofing.
Most of their previous clients praised their professionalism, especially when it comes to following specific instructions.
Their products are compatible with many properties, as they can cater to rooms already built and those that are still being constructed.
And it’s not hard to see why, especially when you consider their range of soundproofing products, which includes walls that specifically trap bass sounds, acoustic walls that control reverberations, and panels that specifically soundproof air conditioners.
I was also seriously impressed with how creative they are in applying the materials to different properties to match its current design while being unobtrusive.
Now, if there’s one area where they could step up their game a bit, it’s their response time to their website contact forms. Sometimes it takes them up to a week to get back to you.
Another thing to note is that their team is smaller compared to other soundproofers in Adelaide. This means they might not be able to take on many clients at once.

Pros
- Stunning designs
- Great for minimalist buildings
- Has worked on many corporate rooms
- Collaborative with clients
Cons
- High fees
- Slow to finish projects
Acoufelt has some of the most stunning designs I’ve seen for soundproofing. They are minimalist, elegant, and easy to install in various types of properties.
Their designs are ideal for minimalist buildings, which is why they have attracted corporate clients like SHAPE, Interite, Palm Lakes Resort, and Rock Ventures.
I had a conversation with one of the companies they worked with, and I was delighted to learn that Acoufelt is highly collaborative with their clients. The company representative mentioned that they take the time to guide you through their different products.
Moreover, he emphasized that Acoufelt ensured that the specific needs of their speech pathology clinic, such as colorful shapes and designs for children, were met.
When I visited the room that Acoufelt worked on, I observed that the soundproofing was designed well and the material had a sturdy feel to it and was effective in blocking noise from outside.
However, one downside is that their fees are on the higher side. Additionally, their projects may take some time to complete, typically spanning weeks.

Pros
- Affordable
- Wide range of acoustic foams
- Great for custom design
- Online store is convenient to use
Cons
- Designs are too simple
- Staff has limited capacity for installations
Advanced Thermal Supplies’ strength lies in the affordability of their products. Their rates are budget-friendly for residential and commercial projects.
Moreover, the soundproofing solutions they offer are well-rounded, including acoustic foams, sound absorption foams, composite-style foams (providing thermal protection as well), and cab foam for vehicles.
A friend of mine who owns a music studio spoke highly of their custom-made acoustic cover. He was particularly impressed with the added metal framework that enhanced the studio’s appearance.
I visited the room where the cover was installed and found the soundproofing to be superb. It’s also durable and firm.
Additionally, their online shop is user-friendly and straightforward. The interface is simple, and they offer fast delivery.
That said, I did notice that the designs of their materials tend to be somewhat simplistic. There isn’t much variety in colors and patterns.
Furthermore, the company has a limited installation staff. You may need to hire a tradesman separately to handle the job, which can be inconvenient.
