The 5 best insulation providers in Brisbane that homeowners and builders count on
It’s fair to say that having a well-insulated space is high on the wish list. Heat inside when it’s cold, so the electric bill doesn’t spike from running the heater, cooler during the hot season without blasting the AC, and less outside noise—who wouldn’t want that, right?
But insulation isn’t always the priority in building a home or planning an upgrade. Sometimes, it becomes a consideration later, after realizing the need for better energy efficiency or a cozier environment.
The best insulation providers in Brisbane we’ve rounded up here can surely help. Experts in installation, removal, and assessments, they’re counted on by homeowners and builders for their quality materials and methods—making every project feel more secure and complete.
How much does insulation cost in Brisbane?
Insulation in Brisbane typically starts at $8 per square meter, with full-house projects ranging between $3,500 and $6,600 or more. Final costs depend on insulation type, area covered, property size, and whether old insulation needs removal.
1. Brisbane Insulation
Address: 4/10 Facit St
Phone: +61 7 3088 6933
Business hours: Tuesday-Friday, 7:30 AM to 4:30 PM
Brisbane Insulation has been trusted by over 15,000 Aussie homeowners since 2014. A great number of those clients point to the team that’s said to carry out the work professionally and with attention to detail, leading to warmer homes and less reliance on heaters.
By ‘work,’ we mean removing old insulation and installing new systems for the roof, underfloor, walls, or ceiling. People often appreciate the installers’ honesty and guidance in choosing the right fit among Knauf Insulation Earthwool batts, Pink Batts, spray foam, and more.
There’ve just been a couple of concerns regarding their roof, including noted gaps, messy handiwork, and leftover old insulation. Others reported lingering—though non-toxic—odors from spray foam that caused discomfort and wished they were told about it beforehand.
Still, being an EEC (Energy Efficiency Council)-certified installer reassures most homeowners that lower power bills await and their insulation will perform properly. Plus, Brisbane Insulation is known for having affordable rates, clearly disclosed during the quote process.
Guided me to the right insulation, professional job, and I didn’t need the heater
“Very happy with Brisbane Insulation. Matt was great he worked with me & I trusted him to guide me to the right Insulation. I had just purchased my house, and omg it was so cold. I could certainly tell the difference once insulated didn’t need the heater and just 1 blanket. The 2 workers installing the insulation were great, very professional and did a great job.”

2. Outback Insulation
Address: 8 Richards Rd
Phone: +61 7 3888 9919
Business hours: Monday-Friday, 9:00 AM to 4:30 PM
Outback’s most popular insulation products include the R1.3 Rhino Roofing Blanket, Hardie Fire, and Vapor Permeable Building Wrap. They’ve supplied, delivered, installed, and removed these at fair quotes, efficiently, and with helpful advice—as clients say.
That goes for ceilings, roofs, walls, sheds, underfloors—even vans and garage doors in both homes and buildings. They also have an acoustic option for soundproofing, in which a homeowner especially praised the team’s expertise and photo updates.
Clients received quick responses to their inquiries, too. But some expressed frustrations over delays, reporting jobs that stretched up to four times longer than promised due to subpar work, certain slow installers, or technical requests like needing house plans before a quote.
The good news is that Outback’s HIA (Housing Industry Association) membership reflects the team’s commitment to ongoing training and accountability. Others even return for the second time or are simply very appreciative of their willingness to provide the proper follow-ups.
Professional, efficient team, took progress photos, and a big improvement
“Luke and the team were very professional and efficient. They knew exactly what they were doing and even took progress photos then shared them with me. We noticed a big improvement in sound and temperature throughout the whole house. Would highly recommend to anyone looking at insulation installation.”
– Jake Wildeboer, Google Review
Process without any issues—friendly and efficient, from office staff to installation team
“We have found the whole team from office and admin staff to the installation team to be friendly, efficient and professional. The process has been without any issues and to my amazement and appreciation the men arrived at exactly the time quoted.We would definitely recommend Outback Insulation. Thank you Jodie and team.”

3. Austral Insulation
Address: 129 Balham Rd
Phone: +61 7 3249 1888
Business hours: Monday-Friday, 7:00 AM to 4:30 PM
For over 42 years, Austral has installed insulation in homes and commercial buildings while also supplying DIY builders in bulk. We’re talking Bradford Gold ceiling and wall batts, New Generation Soundscreen for more quiet, and Rockwool fire protection.
Although rates aren’t listed online, many clients share getting great pricing or competitive quotes. Then again, it’s worth noting that those quotes have at times been met with slow or no response and occasional uninterested customer service over the phone.
The upside is the team—often described as polite, on time, and happy to go the extra mile, whether it’s cleaning up afterward or recommending suitable materials. Not to mention their low-allergen glasswool products, approved by the National Asthma Council Australia.
Clients also find it convenient that Austral provides roof ventilation, including Windmaster (aluminum) and TurboBeam (clear acrylic). EnviroSeal Roof Sarking is another popular choice among builders as it keeps condensation in check and gives extra thermal insulation.
Most pleasant—went the extra mile, gave great pricing, and delivered on time
“I have not come across this level of service in a VERY long time and I cannot talk highly enough of the team at Austral Insulation Brisbane. While insulating my roof is probably the worst job I’ve ever had to do, dealing with Mark, Cory and the guys was most pleasant. They were more than happy to help, went the extra mile, gave great pricing, delivered on time etc.”

Very nice to deal with and went extra miles to help me select suitable products
“Very nice to deal with. This is the only one visiting site to inspect and quote. Steve went extra miles to help me selecting the most suitable products for my small project. He delivered the order himself on the same day of order (yes that is a long weekend Sunday). Brought some tools and explained carefully on what to do. If you want to have roof or wall insulation installed, I highly recommended you to contact them. I felt lucky find them myself.”

4. Ecolife Solutions
Address: 23 Terrence Rd
Phone: +61 7 3881 2300
Business hours: Monday-Friday, 7:00 AM to 3:00 PM
Business owners and DIY installers make up many of Ecolife Solutions’ customers. One regularly purchases roofing blankets, another sources all their insulation exclusively from Ecolife, and some have been dealing with the company for a number of years.
Among the reasons why are the competitively priced, quality products like the eco-friendly Earthwool ceiling (from $66.93), acoustic (from $89.50), and external wall (from $89.50) insulation batts. Add to that the team’s timely deliveries and friendly, helpful attitude.
It’s also good to mention that they have a Eurofins Indoor Air Comfort Certification, which guarantees very low emissions. Simply put, Ecolife’s insulation won’t release harmful chemicals into the air over time—though regular house checks won’t hurt, too.
While most praise the customer service for being outstanding, a few clients did run into unanswered calls and emails, as well as unclear explanations for extra fees. These were later revealed to be for rush orders and complex requirements like mixed material projects.
Competitive prices, great products, and deliveries are always on time
“We use Ecolife for all of our Permastop/Roof blanket for our Metal Roofing Business. We find their prices extremely completive for such a great product and the team go above and beyond and are professional and friendly. Their deliveries are always on time and exactly what we ordered and the drivers always have a smile on their face which speaks volumes about a Company. We are very happy that we have found such a great supplier!”

Professional and went above and beyond to get me the product I required, on time
“I had issues with another supplier and my insulation was not delivered on time. I called ecolife solutions to see if they could help me out and they went above and beyond to get me the product I required. I called at 7am and had the insulation delivered to my house by 930am. I live an hour and half from their warehouse. Thankyou so much for your professionalism and timeliness!”

5. Roof Suckers
Address: 175 Elliott Rd
Phone: +61 405 451 169
Business hours: Monday-Saturday, 7:00 AM to 7:00 PM
First off, the name Roof Suckers stems from their specialty—vacuuming loose or old insulation before installing new material. And clients say the team does it with impressive workmanship, accompanied by genuine care, efficiency, and a thorough cleaning service after.
Homeowners rarely had communication troubles, with installers voluntarily sharing before-and-after photos and videos of the insulated space. When problems did arise, they were usually due to customer service not returning messages or coming across as disinterested.
What makes things better is that those who had their walls, ceilings, and floors insulated by Roof Suckers enjoy savings of up to 45% a year on their power bills. Roofs are covered, too, though a few clients mentioned lights being left loose or tiles not put back properly.
Even so, customers are grateful for how the team took the time to clearly and honestly explain everything throughout. Also, exact rates may not be laid out on the website, but many vouch for the low costs they paid and the transparency of the pricing along the way.
Courteous, professional team and a service of honesty, efficiency, and low cost
“Excellent company to deal with, Greg and Tammie were very quick, courteous and professional. They provide the genuine old fashioned Aussie service of honesty, pride, efficiency and low cost. I cannot recommend them highly enough, and their team were all happy and worked really quickly. 10 stars to Roofsuckers.”
– Rosemary Paton, Google Review
Top-notch workmanship with genuine care, helpful every step, and transparent pricing
“Absolutely outstanding service from Tammi, Greg, and the entire Roof Suckers (QLD) team! From start to finish, they were friendly, professional, and incredibly easy to deal with. It’s rare to find a team that combines such top-notch workmanship with genuine customer care — but these guys nailed it. Tammi and Greg were communicative and helpful every step of the way, and the whole crew worked efficiently and left everything spotless. On top of all that, their pricing was very fair and transparent. Highly recommend Roof Suckers (QLD) to anyone looking for a trustworthy, down-to-earth team that delivers excellent results with a smile. Would highly recommend to anyone needing insulation removed!”
