Cellulose insulation in Moreton Bay.
From the Redcliffe peninsula to the Caboolture and Pine River flats, Moreton Bay mixes bayside beach-shacks with inland acreage and stumped homes. We bring factory-direct cellulose up from Tiaro and insulate them all.

From a local
“I'm so amazed at the difference insulation has made to our home. Peter and his team spent 2 days doing our insulation and they are super friendly and have done an amazing job. Of course I can't see it but the fact that I cant even tell its 6 degrees outside when I wake up in the morning speaks for itself. Communication is also A+ Have wasted so much money attempting to heat and cool an uninsulated home. Highly recommend this company. Worth every $”
“Good value for money Great job.”
“Excellent customer service. Highly recommended. Has a profound knowledge of insulation products and has the best interest of his customer.”
The local picture
What Moreton Bay homes actually need.
On the Redcliffe peninsula the bay keeps things mild and humid, so the priority is a moisture-tolerant, well-vented roof and keeping salt-laden air from loading up the roof space. Move inland to Caboolture and the Pine River flats around Lawnton and you lose that coastal cushion: cold air drains and pools overnight, frost forms in the low-lying pockets, and summers turn hot and sticky away from the sea breeze. Those inland homes, many lowset or on stumps, benefit from ceiling AND underfloor insulation, not just a cool-the-house-in-summer approach.
Moreton Bay in brief
Founded
City of Moreton Bay was formed in 2008 by amalgamating the City of Redcliffe and the Shires of Pine Rivers and Caboolture — but Redcliffe itself is where Queensland began, with the colony's first European settlement landing on 13 September 1824.
People
476,340 at the 2021 ABS Census (City of Moreton Bay LGA35010), the third most populous local government area in Australia, and estimated to have grown past 522,000 by 2024.
Industry
Health care and social assistance is the single largest employer, followed by construction and retail. The region also has a strong horticulture base in the Caboolture-Wamuran hinterland and a growing education sector anchored by UniSC's Petrie campus.
Setting
A large bay-to-hinterland region 20-44 km north of the Brisbane CBD, running from the Redcliffe peninsula and Bribie Island on the Moreton Bay coast, across the fast-growing Caboolture-Narangba-North Lakes corridor, up into the green hinterland around Woodford and Wamuran. Humid subtropical climate — hot, muggy summers and mild winters.
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 Bruce, a fellow Moreton Bay local, reckons about us.
Filmed on a real Caboolture job — not a paid actor.
Read the transcript
Peter: We've just cleaned up and tidied up, and I'm here with Bruce. What did you reckon about your job, Bruce? Bruce: Yeah, good job, Peter. You could've picked a better day, when it wasn't so hot for me! But yeah, good job — I saw the amount that went in, and I know the trouble you went to. Peter: Your job was a top-up — someone else had already insulated it with the same kind of product, they just hadn't put enough in, and you could see it.
Moreton Bay climate
The weather your insulation has to handle.
- Hot days a year (the air-con driver)
- Redcliffe averages about 21.4 days a year at or above 30C and 1.4 days at or above 35C, packed into Dec-Feb, with January alone running roughly 6.4 days over 30C. Source: Bureau of Meteorology, Climate statistics for Australian locations, Redcliffe Council station 040697, record 1981-2004.
- Warm summer nights (the comfort killer)
- The mean January overnight minimum is 21.9C and the warmest January night on record reached 27.0C. When it stays this warm overnight the house can't shed the day's heat, so the insulation that slowed the daytime gain is what lets the bedrooms cool down. Source: BoM Redcliffe Council 040697, record 1981-2004.
- Hottest temperature ever recorded
- 40.1C, recorded on 07 December 1981 at Redcliffe (BoM station 040697). The second-hottest was 38.4C on 08 January 2004. That December 1981 figure is the peak load your ceiling cavity ever has to hold back. Source: BoM Climate statistics, Redcliffe Council 040697.
- Summer humidity (why the heat bites harder)
- South-east Queensland summers are muggy: at the nearest official humidity gauge, Brisbane Aero, January averages about 66% relative humidity at 9am and 63% at 3pm, holding through Dec-Feb. High humidity makes a given temperature feel hotter and slows the body's own cooling, so keeping indoor temperatures down with a good ceiling matters more here. Source: BoM Brisbane Aero station 040842, 9am/3pm humidity record 1994-2010 (Redcliffe does not record humidity).
- Mild, near frost-free winters
- Being on the bay, Moreton Bay rarely frosts: the mean July minimum at Redcliffe is about 9.9C and the lowest ever recorded is 0.0C, on a single morning across 1981-2004. This is a cooling-dominated climate, so the insulation job here is overwhelmingly about keeping summer heat out. Source: BoM Redcliffe Council 040697, record 1981-2004.
- Annual rainfall and the wet season
- Mean annual rainfall at Redcliffe is 1087.6 mm, falling on about 124 days a year and heavily summer-weighted, with February the wettest month at roughly 163 mm. A wet, humid wet-season is exactly why cellulose, with its borax treatment and gap-free fill, suits these coastal roof spaces. Source: BoM Redcliffe Council 040697, record 1981-2004.
Across south-east Queensland the Bureau of Meteorology records that average temperatures have risen by more than a degree since national records began in 1910, with most of that warming since 1950, and the longer-term trend is for more hot days and warmer nights. For a Moreton Bay home that means the muggy nights that already stop a house cooling down are turning up more often, and the ceiling insulation that keeps the daytime heat out is doing more work each summer than it was a generation ago.

Moreton Bay at a glance
- Climate zone
- Climate Zone 2 — what R-value that needs
- Postcodes
- 4510, 4020, 4501
- Local picture
- Caboolture (≈29,500) anchors a fast-growing region; Redcliffe (≈10,500) and Lawnton (≈5,900) round out a mix of coastal and inland river-flat housing.
Moreton Bay is NCC Climate Zone 2, but the inland river-flat towns lose the coast's moderating effect, so a good ceiling blanket earns its keep on both hot summer afternoons and the surprisingly cold, frost-pocket winter mornings.
What Zone 2 actually needs — straight from the NCC
Moreton Bay 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 Moreton Bay than in it.
Moreton Bay splits into two climates that matter for an insulation job. The bay side, Redcliffe, Scarborough and Bribie Island, is buffered by the water: mild winter nights with a July mean minimum around ten degrees and essentially frost-free, and the sea also shaves the top off summer afternoons. Move inland to Caboolture, Wamuran and Woodford in the D'Aguilar foothills and you lose that maritime buffer: nights run several degrees colder, the odd light frost shows up in the valleys, and summer days push a bit hotter. A note on stations: the Bureau has no long-record temperature gauge actually in Caboolture, Woodford or Bribie township, so the inland rows below use the nearest official gauges, Beerburrum Forest Station for the Caboolture and Woodford foothills and Samford CSIRO for the D'Aguilar valleys, which bracket the inland behaviour. Bayside uses Redcliffe, and Cape Moreton Lighthouse shows the pure-maritime extreme.
| Town | Height | Avg July night | Frosts / year | Avg summer day |
|---|---|---|---|---|
| Redcliffe / Scarborough (bayside) | 25 m | 9.9 C | None — lowest ever recorded just 0.0 C; the bay keeps nights mild | ~28-29 C (Dec 28.1 / Jan 29.0 / Feb 28.5) |
| Bribie Island (bayside) | ~3-5 m | ~10-11 C (no on-island gauge; sits between Redcliffe 9.9 and Cape Moreton 13.3) | None — surrounded by water, frost-free | ~28-29 C |
| Cape Moreton (bay island, maritime reference) | 100 m | 13.3 C | None — pure maritime; mildest winter nights in the region | ~26-27 C (Dec 26.2 / Jan 27.1 / Feb 27.0) |
| Caboolture / Woodford (Beerburrum Forest Stn proxy) | 48 m | 9.5 C | Occasional light frost — extreme low 1.8 C recorded; cooler nights and hotter summer days than the bay | ~30 C (Dec 29.8 / Jan 30.3 / Feb 29.8) |
| D'Aguilar foothill valleys (Samford CSIRO proxy) | 53 m | 6.7 C | Genuine frosts — extreme low -2.7 C; valley cold-air drainage well inland of the bay | ~29 C (Dec 29.3 / Jan 29.4 / Feb 28.7) |
- Bayside buffering: Redcliffe (BoM 040697, elevation 25 m) has a July mean minimum of 9.9 C and has never dropped below 0.0 C across its 1981-2004 record — the bay water keeps winter nights mild and frost off the ground.
- Inland cold-air drainage: Samford CSIRO (BoM 040241), a D'Aguilar-foothills valley, runs a July mean minimum of 6.7 C — over three degrees colder than bayside — and has fallen to -2.7 C, which is real frost.
- The Caboolture and Woodford foothills (Beerburrum Forest Station, BoM 040284, elevation 48 m) sit in between: a July mean minimum of 9.5 C but an extreme low of 1.8 C, so the odd light frost does occur away from the water.
- Summer flips it: inland Beerburrum averages a January maximum of 30.3 C against bayside Redcliffe 29.0 C and bay-island Cape Moreton just 27.1 C — the sea breeze takes the edge off coastal afternoons.
- Cape Moreton Lighthouse (BoM 040043) shows the pure maritime case: a July mean minimum of 13.3 C and no frost ever recorded — about as far from the inland cold as a bayside home gets.

What we’d recommend in Moreton Bay
The insulation that suits Moreton Bay homes, and why.
Redcliffe's humid bayside air (peaking around 59% in February) loads up poorly-vented roof spaces and grows mould. A cellulose ceiling plus good roof ventilation helps manage that moisture.
Caboolture sits on the Bruce Highway, and both Caboolture and Lawnton are on the North Coast rail line. Dense cellulose in walls and ceilings dampens that highway and train noise better than batts.
The region's many stumped Queenslanders lose comfort through the floor, so underfloor polyester suits the humid, ventilated subfloor and lifts year-round comfort.

Underfloor, done right
Underfloor insulation in Moreton Bay: only worth it if you're up on stumps
If you've got one of those high-set timber Queenslanders or a raised beach house — and Redcliffe, Margate, Woody Point and the older Caboolture and Bongaree streets are full of them — winter is exactly when you feel the floor. Those bare floorboards over an open crawlspace are only about R0.25 on their own, which is the figure in the Government's YourHome guide, and that's next to nothing. Cold air sweeps under the house all night, the boards go cold underfoot, and the warm air you've paid to make rises and drops straight back out through the gaps between the boards, so you heat the room and the heat sinks through the floor and you do it again.
Summer's the same problem running the other way. You run the air-con, and cool air is heavy, so it sinks; in a high-set home it sinks straight down through the floorboards and pours out into the crawlspace, and the unit runs and runs and never quite gets the room cold. Sealing and insulating that floor keeps the cool air where you paid to put it. And coverage is the whole game down there — YourHome puts it plainly that even a small gap can greatly reduce the insulating value, and the Australian rating work backs it up: ICANZ's 2024 figures show obvious gaps over about 6% of an area roughly halve the effective R-value, so a rated R5 ends up performing like about R2.4.
Now the honest part, because I'd rather tell you straight than sell you something that won't pay off. Underfloor is for the homes up on stumps with air moving underneath — that's where it earns its keep. If you're in one of the slab-on-ground estate homes out at Morayfield, Narangba, North Lakes or the newer Bribie estates, there's no crawlspace to insulate and underfloor isn't your job — your money goes in the ceiling, every time. And wherever we do fit it, the NCC is clear the insulation has to be held firmly in place against the underside of the floor, because if it sags away from the boards over the years it stops working, so it has to be installed to stay put.

Moreton Bay questions
Insulation in Moreton Bay — your questions, answered.
I'm in a slab-on-ground house out at North Lakes or Narangba. Do I need underfloor insulation?
No. If your floor is a concrete slab poured on the ground there's no crawlspace to insulate, so underfloor isn't your job — your money goes in the ceiling, every time. Underfloor only earns its keep on the high-set timber homes with air moving under the floor. Tell us whether you're up on stumps or down on a slab and we'll tell you honestly which job is worth doing.
Moreton Bay barely gets cold — is insulation really worth it for the summer?
That's exactly when it's worth it. This is a cooling-dominated climate: Redcliffe averages around 21 days a year over 30C and the January nights sit near 22C and won't drop. A bare ceiling bakes all afternoon and the house can't shed it overnight, so the air-con runs and runs. A deep, gap-free ceiling is what cuts that cooling load — it's far more about keeping summer heat out here than keeping winter heat in.
My place is bayside at Redcliffe and it gets humid and muggy. Does that matter for insulation?
It does. Humidity makes a given temperature feel hotter and slows your body's own cooling, so keeping the indoor temperature down matters more on the bay. Cellulose is borax-treated and pumped in gap-free, which suits these humid coastal roof spaces, and if a roof ever leaks the cellulose holds the water in one spot and dries out rather than letting it run across the whole ceiling like batts do.
Why cellulose instead of the batts the last bloke quoted?
Coverage is the whole game. Batts are only as good as how well they're fitted, and the gappy, settled batts I pull out of Moreton Bay roofs every week aren't doing much — the Australian rating figures show gaps over about 6% of an area roughly halve the effective R-value. Cellulose is pumped in to fill every gap, corner and penetration with no joins, it covers the joists batts leave bare, and it's the best fire and sound performer for the depth. It's not the cheapest, but it's the one you never have to think about again.
Should I just pack in as much insulation as possible?
No, and I'll talk you out of it. Past the right R-value for this climate zone, more does nothing extra — it's like sunscreen, once you've got the cover, piling on more doesn't make you any safer. Moreton Bay is NCC Climate Zone 2, and we install to the right added R-value for that zone rather than selling you a bigger number than your roof can use.
Do you come out and measure before you quote?
We do all our quotes online, fixed price, and it's never bumped when we turn up. You send through the details and a few photos and we price it properly off that, so you're not waiting around for a salesman or getting a different number on the day. If you tell us whether you're on stumps or a slab and what your roof's like, we'll give you an honest quote and tell you if a job isn't worth doing.
I've already got old batts up there. Do they have to come out first?
Usually not — and that's a big saving. We can top straight over old batts with cellulose, which fills the gaps they've left, covers the joists, and saves you the mess, landfill and dump fees of ripping them out. About 100mm of cellulose over the top adds roughly R3 to whatever's already there. We only pull old insulation out if it's wet, vermin-fouled or it has to go for another reason.
