🏠 Hot in summer. Cold in winter. Noisy all year?
The problem might not be your air conditioner, windows or roof.
Most Perth homes have a hidden gap inside their walls that lets heat, cold and noise move freely through the home. ComfortWall fills that cavity with premium ROCKWOOL® stone wool insulation — helping create a home that's:
✅ Cooler in summer
✅ Warmer in winter
✅ Quieter year-round
✅ More energy efficient
✅ Non-combustible and moisture resistant
No major renovations. No mess. Most homes completed in a day.

There’s a better way — you just have to ask.
🏠 Did you know about 20% of your home’s heat can escape straight through your walls?
Most double brick homes in Perth have a gap between the bricks - and if that gap isn’t insulated, heat moves through it surprisingly easily.
In this video I explain cavity wall insulation and how our ComfortWall works to improve comfort inside your home.
It sits between the outer and inner brick walls, helping to slow down heat transfer.
That means:
🔥 Winter: keeps the warm air inside your home
☀️ Summer: helps stop outside heat getting in
🔇 Bonus: also helps reduce outside noise thanks to its acoustic properties
Brick walls themselves only provide a very small amount of insulation (around R0.4), but adding cavity insulation lifts the system to roughly R1.7–R1.8, making a noticeable difference to comfort and energy efficiency.
A lot of homeowners describe it like this:
🧊 It turns your home into more of an “Esky” —
the temperature stays more stable and your heating or air-conditioning works far more efficiently.
Even better, we can usually provide a fast quote using Google Earth and Nearmap, before coming out for a quick inspection.
