Cavity Wall Insulation
Did you know that without wall insulation your home can lose or gain as much as 25% to 35% of its heat in winter and cool air in summer? This means that if your walls aren’t properly insulated, you’ll struggle with freezing winters, sweltering summers, and sky-high energy bills.
While most people prioritise roof and ceiling insulation, wall insulation is still crucial for overall comfort and energy efficiency.
Rapid Insulation’s highly skilled team are able to quickly and effectively install quality wall cavity insulation in homes of all sizes. In fact, we’ve helped hundreds of homeowners in Melbourne and Sydney enjoy warmer winters, cooler summers and lower energy bills.
With Rapid Insulation, you’re not just buying insulation. You’re investing in year-round comfort.

FAQs
Why should I insulate my walls?
Wall insulation helps regulate your home’s temperature, keeping it warmer in winter and cooler in summer. It reduces your reliance on heating and cooling systems, lowers energy bills, and creates a more comfortable and quieter home environment.
What type of wall insulation do you use?
At Rapid Insulation, we use premium thermal and acoustic batts as well as Knauf Supafil CarbonPlus, designed specifically for double brick masonry cavities. It provides long-lasting thermal efficiency and excellent soundproofing, making it one of the most effective solutions on the market.
Can wall insulation be installed in existing homes?
Yes. Our team specialises in retrofit wall insulation for existing homes. We use non-invasive installation methods, including roof access and blow-in wall insulation where suitable, to fill wall cavities with minimal disruption. Should we need to drill internal walls, we can do so by drilling a hole no larger than 20c coin. Following this, we’ll patch and paint the access points so your walls look as good as new.
How long does the installation take?
Most wall insulation jobs are completed within a single day. Our experienced team works quickly and cleanly to minimise disruption to your household.
Will insulation really make a difference to my energy bills?
Absolutely. Poorly insulated walls allow heat to escape in winter and creep in during summer. By insulating your walls, you can reduce energy loss by up to 25%, which means lower bills and less strain on your heating and cooling systems.
Does wall insulation help with noise?
Yes. In addition to temperature control, wall insulation provides acoustic benefits. It reduces outside noise entering your home and limits sound transfer between rooms, creating a quieter, more peaceful environment.
Is there a warranty on your insulation?
Yes. All our wall insulation comes with a 70-year manufacturer’s warranty, so you can feel confident knowing your home will stay comfortable for decades to come.
