Where we work · Climate Zone 2
Cellulose insulation in Redlands.
Cleveland and the Redlands sit on Moreton Bay, where the daily sea breeze takes the edge off summer and the bay keeps winter nights mild. We insulate bayside homes with breathable, settle-free cellulose from our Tiaro factory.
Where we work
177+ Redlandshomes — and what your neighbours say.
Every red dot on the map is a home near here we’ve quoted, advised or insulated (de-identified) — recent records only, a fraction of what we’ve done since 1986.
From a local
“Peter did an amazingly clean job of what seems to be amazingly messy product. Worth every cent though as I have had this insulation installed in a previous home.”
“Our insulation job has been completed with Insulation Qld - Comfort Zone. Everything went well and I would recommend the service to others. Their communication was excellent and they also guarantee their work and give lots of information.”
“He did a good job. I was happy with everything. He was quick, tidy and came out the next day. He did very well job. I would give him 5 stars and I'm happy to recommend!”
The local picture
What Redlands homes actually need.
Right on the bay, Cleveland's sea breeze trims the worst of the summer heat and the water keeps winter nights milder than inland Logan, but that same coastal air is humid and salt-laden. So the insulation priority here is a moisture-tolerant, well-vented roof: a quality cellulose ceiling plus good roof breathing to manage summer humidity and condensation, rather than fighting the kind of heat extremes the inland suburbs cop. Cellulose's breathable, non-corroding fill suits a bayside roof cavity better than fibreglass or foil.

Why Comfort Zone
Cellulose insulation, by the family that makes it.
The only cellulose insulation maker still operating in Queensland.
We manufacture every bag ourselves in our own factory at Tiaro. The other Queensland cellulose makers have closed down over the years — these days our competitors buy theircellulose from us. Choose Comfort Zone and you’re dealing with the family who actually makes the product, start to finish.
We make our own cellulose
Most cellulose insulation sold in Australia is manufactured interstate — in Victoria, South Australia or WA. Ours is made right here in our own Tiaro factory, so you deal with the family who makes it, not a sales rep reselling someone else's product.
Three generations, since 1986
Peter learned the trade from his father, Lyle, and runs the business today with his sons. A real family business that's been insulating Queensland homes for nearly 40 years — not a franchise call-centre.
QR-code batch-tracked bags
Every bag we pump into your roof is QR-coded and tracked back to its production batch and your job — full traceability that even the big national brands can't offer.
Don’t take our word for it
Here’s what Alf, a fellow Redlands local, reckons about us.
Filmed on a real Cleveland job — not a paid actor.
Read the transcript
Peter: I'm here with Alf — I've just insulated his garage. What did you think, Alf? Alf: Yes, very good. The garage here was very hot. The rest of the house was air-conditioned and insulated when we were building, but the garage was left over, and I noticed the difference in temperature straight away. So I decided to get the garage insulated as well — and sitting here now, I can already feel it.
Redlands climate
The weather your insulation has to handle.
- Climate type
- Humid subtropical, no real dry season — hot wet summers, mild winters, moderated by Moreton Bay (BoM long-term station data, Redlands HRS / Alexandra Hills, station 040265)
- Hot days at or above 30C (per year)
- About 18 days a year reach 30C or hotter at the long-term Redlands HRS gauge, station 040265 (record 1953–2013) — concentrated Jan–Feb, the summers your air-con fights hardest
- Warm summer nights (Jan mean overnight minimum)
- Mean January overnight minimum about 20.0C at Redlands HRS, station 040265 (record to 2010) — bayside nights barely cool down, so an under-insulated ceiling keeps radiating stored heat into bedrooms
- Hottest on record (full date)
- 38.2C recorded 24 February 2008 at Redlands HRS, station 040265 (record 1965–2013) — late summer is when ceiling heat-gain peaks (date/value to be read off the official BoM Climate statistics table before publishing)
- July (coldest month) mean overnight minimum
- About 8.2C bayside at Redlands HRS, station 040265 — the bay keeps the coast effectively frost-free; only low-lying inland gullies near Capalaba and Mount Cotton see the rare light radiation frost
- Annual rainfall
- About 1271.6mm a year, summer-dominant (Jan–Mar the wettest months) at Redlands HRS, station 040265 — a humid bay climate with no dry season, so a sealed, well-insulated ceiling pays off year-round (rainfall total to be confirmed against the BoM table)
South East Queensland is trending hotter: the Bureau of Meteorology's State of the Climate reporting shows Australia has warmed by around 1.5C since national records began in 1910, with more frequent and longer heatwaves the clearest local effect. For a bayside Redlands home that already gets warm, humid summer nights with little overnight cool-down, that means more days and nights leaning on the air-con. A deep, gap-free cellulose ceiling is the one upgrade that keeps paying back as the cooling season gets longer.
Note: Typical figures are from the Redland (Alexandra Hills) BoM station; published record extremes weren't available at research time.

Redlands at a glance

- Climate Zone 2 — what R-value that needs
- Postcodes
- 4163
- Local picture
- Cleveland (≈15,850) is the Redlands' bayside town centre, surrounded by detached homes that look straight onto Moreton Bay.
The Redlands are NCC Climate Zone 2, and being right on Moreton Bay, the job here is less about beating harsh heat and more about a moisture-tolerant, well-ventilated roof that handles humid, salt-laden coastal air.
What Zone 2 actually needs — straight from the NCC
the Redlands sits in NCC Climate Zone 2, where the code asks for about R2.5 of added ceiling insulation (NCC 2022 Housing Provisions, Part 13.2.3, Table 13.2.3c) — and we install a deep, gap-free R3.0 cellulose blanket as standard, about 20% over the minimum. Our climate is cooling-dominated, so there's no point chasing a giant R-value the weather won't reward; getting the blanket seamless and gap-free across the whole ceiling matters far more, especially under a hot tile or metal roof. Beware quotes citing “R5.5+” as the ceiling figure — that's a total-system / NatHERS number for the cold southern states, not what we need here.

Colder than you think
It’s colder around Redlands than in it.
Here is the comparative winter-climate snapshot for the Redlands, built from Bureau of Meteorology long-term station averages. The pattern is classic maritime moderation: the closer you sit to Moreton Bay, the warmer and steadier the nights. Bayside Cleveland, Victoria Point and Redland Bay are effectively frost-free, while the inland fringe around Capalaba and the Mount Cotton hills cools off harder on still, clear winter nights and can pick up the occasional light radiation frost where cold air drains into low gullies. July is the coldest month across the whole district, and summer afternoons are remarkably even — low-to-high 28s right across the area — so the real bayside-versus-inland difference is at night, not in the afternoon.
| Town | Height | Avg July night | Frosts / year | Avg summer day |
|---|---|---|---|---|
| Cleveland / Alexandra Hills (Redlands HRS, central bayside) | 16 m | 8.2°C | Effectively frost-free at the coast — Moreton Bay keeps nights mild | ~29°C (Jan) |
| Victoria Point / Redland Bay (southern bayside) | ~5–15 m | ~8–9°C (bayside, per Redlands HRS) | Frost-free bayside strip — same maritime moderation as Cleveland | ~29°C |
| Capalaba / Mount Cotton (inland Redlands fringe) | ~20–80 m (Mt Cotton hills higher) | ~9°C (est., bracketed by bayside and inland gauges) | Mostly frost-free, but cold-air drainage in low gullies brings occasional light radiation frost on still, clear nights | ~29–30°C (est.) |
| Logan City (inland reference, just west of the Redlands) | ~10 m | ~9.0°C | Light, infrequent frost possible inland on calm, clear nights | ~30°C (Jan) |
| North Stradbroke Island / Minjerribah (bay islands) | Coastal | Mild — open-ocean maritime | Frost-free — surrounded by ocean that barely changes overnight | Mild coastal maxima |
- Maritime moderation is the whole story for the Redlands: the surrounding ocean barely changes temperature overnight, so the closer a home sits to Moreton Bay, the warmer and steadier its winter nights stay.
- July is the coldest month everywhere in the district. Mean overnight minimums bottom out around 8.2°C bayside at Redlands HRS (station 040265) and around 9°C on the inland side; August is statistically just as cold or only slightly milder.
- Summer afternoons are very even across the Redlands — January means sit around the high-28s to low-30s bayside and inland alike — so the genuine climate difference between bayside and inland is at night, not in the afternoon.
- The bayside strip (Cleveland, Victoria Point, Redland Bay) is effectively frost-free thanks to Moreton Bay; real frost in the Redlands is confined to the occasional still, clear night in low-lying inland gullies around Capalaba and the Mount Cotton hills, where cold air drains and pools.
- The insulation takeaway for this district: cooling-season comfort matters as much as winter. Even, warm summer afternoons plus high coastal humidity make a well-insulated, gap-free ceiling the bigger year-round win than chasing frost protection.

Inland Capalaba / Mount Cotton rows are estimates bracketed by the bayside Redlands HRS gauge and an inland Logan reference — no dedicated long-term-averages station sits in the inland Redlands hills, so those figures are shown as estimates. Bay-island and North Stradbroke / Minjerribah maritime context is qualitative.
A bit about Redlands
We know this patch.
- The Redlands is known as the 'Koala Coast' — one of the last strongholds of wild koalas in South-East Queensland, with the council's Koala Conservation Strategy and the IndigiScapes centre at Capalaba dedicated to protecting them (Redland City Council).
- North Stradbroke Island (Minjerribah), reached by ferry from Cleveland, is the second-largest sand island in the world at about 275 sq km, and home to Naree Budjong Djara National Park, formally declared in 2011 (Queensland Parks and Wildlife; Visit Redlands Coast).
- The Quandamooka people are the Traditional Owners of the Redlands and the bay islands; they were granted native title over most of North Stradbroke Island on 4 July 2011 (National Native Title Tribunal).
- Cleveland Point Lighthouse, a timber hexagonal tower built in 1864–65, still stands on the point — one of only two surviving lighthouses of its form in Queensland (Queensland Heritage Register).
- Cleveland was proclaimed a township on 13 December 1850; the wider Redlands became a shire in 1949 and a city on 15 March 2008 (Redland City Council history).

What we’d recommend in Redlands
The insulation that suits Redlands homes, and why.
Brisbane Airport departures and arrivals regularly track over Cleveland, a documented noise concern since the 2020 runway opened. Acoustic cellulose in the ceiling helps soften the aircraft noise reaching your living areas.
Cleveland's elevated timber homes on Moreton Bay need underfloor protection from salt air, moisture and pests, and polyester handles the damp coastal subfloor well.
The humid bayside climate brings mould and condensation risk; a cellulose ceiling with proper roof ventilation helps keep the roof space dry.

Underfloor, done right
Underfloor in the Redlands: worth it on a high-set Queenslander, useless on a slab
Here is the honest version most blokes will not give you: underfloor insulation is worth it on a raised timber-floored home, and it does nothing for you on a slab. If you are in one of the high-set timber Queenslanders or a stumped bayside cottage around Cleveland, Wellington Point, Ormiston or out on the bay islands, you have got open air moving under your floorboards, and that is exactly where underfloor work pays. But if you are in a newer slab-on-ground place in the Thornlands or Redland Bay estates, your floor sits straight on the ground, there is no cavity to insulate, and I will tell you that up front rather than sell you something you do not need.
On a raised timber floor the physics is simple and it cuts both ways through the year. In winter the air under your stumps gets cold, that cold soaks straight up through the boards, and you end up with that chilly-feet feeling first thing in the morning even with the heater going. In summer it flips: when you have got the air-con running, that cool, heavy air you are paying for slides down and falls straight out through the floorboards into the open subfloor, so the split-system runs longer and your bill climbs. YourHome, the Australian Government's own guide, only credits a bare suspended timber floor at about R0.25, so a snug layer of insulation slung up tight under those joists is what stops the floor being a hole in the bottom of the room.
That 'fit it snug' point is the bit the cheap operators skip, and it is the difference between a floor that works and one that does not. The ICANZ 2024 guidance shows that only about 6% of gaps in a layer roughly halves the effective R-value you are paying for, so a sloppy underfloor job with sagging batts and missed bays gives you maybe half the comfort you thought you bought. We fit polyester underfloor batts hard up against the joists with no slumping and no gaps, and the NCC backs the same principle — insulation has to be installed so it holds its position and rated thickness over the life of the floor. Done properly on a raised Redlands home it takes the cold bite off the boards in winter and stops your cool air falling out the bottom in summer; sold to a slab home it is money down the drain, and that is exactly the sort of thing we will tell you straight.

Redlands questions
Insulation in Redlands — your questions, answered.
I'm right on the bay at Cleveland — our winters are mild, so do I really need ceiling insulation?
You're not buying it for the winter, you're buying it for the summer. The bay keeps your nights mild, but it also keeps them warm and humid, so the house never gets a proper overnight cool-down and an under-insulated ceiling just keeps radiating stored heat into the bedrooms. Around here ceiling insulation is a cooling job first — it cuts the heat load your air-con has to fight on those sticky January nights. That's the bigger year-round win on the bayside than anything to do with frost.
I'm in a newer slab home out in the Thornlands estates — should I get underfloor done too?
No, and I'll tell you that for free. Underfloor only does something where there's open air moving under a raised timber floor. Your slab sits straight on the ground — there's no cavity to insulate, so underfloor would be money down the drain. Put every dollar into your ceiling instead, because on a slab home that's where nearly all your heat is moving.
We've got a high-set timber Queenslander at Wellington Point — does underfloor actually make a difference?
On a place like yours, yes. You've got open air running under your floorboards, so in winter the cold soaks up through the boards and gives you that chilly-feet feeling, and in summer your cool air slides down and falls straight out the bottom. A snug polyester batt fitted hard up under the joists stops the floor being a hole in the bottom of the room. The catch is it has to be fitted tight with no gaps — done sloppy it barely works, which is why we fit it properly or not at all.
There are already old batts in my roof — do I have to rip them out first?
Usually no. If the old batts aren't soaked or rat-infested we pump cellulose straight over the top — it fills every gap they left, covers the timber joists they could never cover, and saves you the mess, the landfill and the dump fees of ripping them out. About 100mm over the top adds roughly R3.0 on top of whatever's already there. If they're full of vermin or water, that's a different conversation and we'll show you the photos.
How much R-value do I need for a Redlands home — is more always better?
No — more is not always better, and anyone telling you to chase the biggest number is having you on. The Redlands is NCC Climate Zone 2, so the ceiling target is around R2.5 added under the current code, not the R5.5 you'll see quoted for cold southern climates. Past the right number for your zone and roof, extra R-value does nothing extra — it's like piling on more sunscreen once you've got a proper coat on. We insulate to what your home actually needs, not to pad the bill.
Do you sell roof vents or whirlybirds to go with the insulation?
No, we don't, and I reckon it's a bit rich for anyone to sell you vents on top of a quality insulation job — it's the 'would you like fries with that' of the insulation world. A sealed, gap-free, fully-insulated ceiling is what keeps your home comfortable. We'll happily repair or remove vents you've already got, but we won't upsell you new ones you don't need.
How do I get a price — do you need to come out and inspect first?
No site visit needed to get a price. Our quotes are done online and they're a fixed price — what we quote is what you pay, we never bump it up when we turn up. You give us the details on your roof and ceiling, we work it out, and you've got a real number to make a decision on. If something on site changes the job, we talk to you first — there are no surprises on the day.
