Cellulose insulation in Hervey Bay.
A flat, low-lying coastal city stretched along the calm, north-facing shore of the Great Sandy Strait in the Wide Bay–Burnett, sheltered from the open ocean by K'gari. Part of the Fraser Coast Regiona We bring our own cellulose fibre insulation up from the Tiaro factory and insulate Hervey Bay homes to keep the summer heat out of the roof and the winter warmth in.
The local picture
What Hervey Bay homes actually need.
Hervey Bay isn't one climate — the bay makes a real difference street to street. The foreshore suburbs sit right on the calm water of the Great Sandy Strait, so the sea breeze keeps them a touch milder day and night. Push inland and up the river toward Maryborough and you trade that bay buffer for hotter still afternoons and noticeably colder nights. Here's how the Fraser Coast towns stack up on t
Hervey Bay in brief
Founded
Settled from the 1860s around the township of Pialba; the seaside townships of Pialba, Scarness, Torquay and Urangan amalgamated and Hervey Bay was proclaimed a city in 1984.
People
57,722 at the 2021 Census (ABS), with a usual-resident count near 60,000 and growing fast — a median age around 48, making it one of Queensland's major retirement and sea-change cities.
Industry
Tourism is the engine — whale watching, K'gari (Fraser Island) ferries, fishing and boating — alongside retirement and lifestyle migration, healthcare, retail and construction serving a fast-growing population.
Setting
A flat, low-lying coastal city stretched along the calm, north-facing shore of the Great Sandy Strait in the Wide Bay–Burnett, sheltered from the open ocean by K'gari. Part of the Fraser Coast Regional Council area, NCC Climate Zone 2.
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. Ours is made at 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.
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 — traceability the big national brands can't offer.

Hervey Bay climate
The weather your insulation has to handle.
- Average summer day (January max)
- 30.3°C mean maximum — BoM Hervey Bay Airport, station 040405 (records 1999–2026)
- Hottest day on record
- 36.8°C on 5 December 2012 — BoM Hervey Bay Airport 040405. 35°C-plus days are rare here; the bay sea breeze usually caps the heat.
- Summer humidity (January 3pm)
- 61% mean 3pm relative humidity (67% at 9am) — BoM Hervey Bay Airport 040405. The mugginess is what makes a hot roof cavity feel worse than the thermometer says.
- Average winter day / mild-winter note
- 21.8°C mean July maximum with a 10.0°C mean July minimum — BoM Hervey Bay Airport 040405. Lovely winter days, genuinely cold mornings.
- Coldest morning on record
- -1.2°C on 16 July 2007 — BoM Hervey Bay Airport 040405. Yes, a frost at the airport — a coastal town still gets cold nights inland of the water.
- Annual rainfall
- 1050.7mm mean per year, wettest Jan–Mar (March 147.9mm), driest in spring (September 33.5mm) — BoM Hervey Bay Airport 040405.
The Hervey Bay Airport record is a short one — the station only opened in 1999 — so it is too young to read a long climate trend off honestly, and we won't pretend otherwise. What the 27 years of figures (1999–2026) do show plainly is a coast of two seasons: long, sticky summers sitting around 30°C with afternoon humidity in the low 60s, and short, mild winters where the days are pleasant but the nights inland of the foreshore drop away hard. The bay water keeps the foreshore suburbs milder, but the airport out at Nikenbah has logged a min of -1.2°C. Whichever way the long-term average drifts, the job for a Hervey Bay home is the same all year — hold the summer heat out of the roof AND hold your warmth in on those cold winter mornings.

Hervey Bay is NCC Climate Zone 2 — hot, humid summers and mild winters. The cellulose fibre insulation job here is led by summer (a gap-free ceiling that blocks the radiant roof heat and saves on cooling), with the same blanket holding your warmth in on the cool winter nights.
What Zone 2 actually needs — straight from the NCC
Hervey 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 fibre insulation blanket as standard, a touch over the minimum. It's a cooling-dominated climate, 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, so it stops the summer heat coming in and holds your winter warmth in. Beware quotes citing an “R4.1+” or “R5.5+” ceiling figure — that's the whole-of-home total-system / NatHERS number, not the added insulation an installer actually fits.

Colder than you think
It’s colder around Hervey Bay than in it.
Hervey Bay isn't one climate — the bay makes a real difference street to street. The foreshore suburbs sit right on the calm water of the Great Sandy Strait, so the sea breeze keeps them a touch milder day and night. Push inland and up the river toward Maryborough and you trade that bay buffer for hotter still afternoons and noticeably colder nights. Here's how the Fraser Coast towns stack up on the numbers that actually decide what your roof needs — all from Bureau of Meteorology stations.
| Town | Height | Avg July night | Frosts / year | Avg summer day |
|---|---|---|---|---|
| Hervey Bay (foreshore – Torquay, Scarness, Pialba) | ~5–13 m | 10.0°C | Rare on the foreshore; the bay water keeps nights milder | 30.3°C (Jan), record 36.8°C |
| Hervey Bay inland (Nikenbah, Booral, the airport) | ~13 m | 10.0°C mean, down to -1.2°C | Genuine cold snaps — airport has logged a frost | 30.3°C (Jan), record 36.8°C |
| Maryborough (up the river) | ~9 m | 8.7°C | Colder river nights than the coast | 30.8°C (Jan) |
| Burrum Heads / Toogoom (open coast, north) | ~3 m | ~10°C (coastal, similar to Hervey Bay) | Rare — right on the water | ~30°C summer days, salt-air exposed |
- Coastal foreshore suburbs run milder both day and night than inland Nikenbah, Booral and Susan River — same town, two different jobs for your insulation.
- Maryborough, just up the river, drops to a mean July minimum of 8.7°C (BoM 040126) versus Hervey Bay's 10.0°C — proof that getting away from the bay water means colder mornings.
- The whole Fraser Coast is NCC Climate Zone 2, so the target added R-value is the same across all these towns — what changes is the roof type and how much old, gappy insulation is already up there.
- Summer afternoon humidity sits around 60–61% across the coast — that muggy heat is exactly what a well-packed roof cavity keeps out of your living rooms.

A bit about Hervey Bay
We know this patch.
- Hervey Bay is the whale-watching capital of Australia — humpbacks come into the calm, protected waters of the bay between roughly July and October each year, on their way down the east coast. A 25-year study found the bay is a genuine social meeting point for the whales, not just a stop-off.
- The bay was named by Captain James Cook in 1770 after Augustus Hervey, the 3rd Earl of Bristol. The traditional owners are the Butchulla (Batjala) people, whose country takes in both the bay and K'gari (Fraser Island) just across the water.
- Hervey Bay is the mainland gateway to K'gari (Fraser Island) — the largest sand island in the world and a World Heritage site — with barge and ferry services running across to the island from Urangan and River Heads.
- The Urangan Pier, built back in 1917 to ship sugar, coal and timber, still reaches about 868 metres out over the bay and is one of the town's best-known landmarks and fishing spots.
- Hervey Bay only became a city in 1984, joining up a string of seaside townships — Pialba, Scarness, Torquay and Urangan — that grew along the Esplanade. It's one of Queensland's fastest-growing regional cities and a big retirement and sea-change destination, with a median age around 48.

What we’d recommend in Hervey Bay
The insulation that suits Hervey Bay homes, and why.
Hervey Bay's humid summer heat sits on the roof and pushes down into the rooms, so a sealed, gap-free cellulose fibre insulation ceiling that keeps it out (and your warmth in come winter) is the biggest comfort win — start here.
Plenty of The Bay's homes are high-set timber catching the sea breeze; polyester underfloor batts keep the floors comfortable and cut the draughts, year-round.
Hervey Bay is one of Queensland's biggest retirement towns, and dense cellulose fibre insulation between rooms and in the ceiling deadens noise as well as heat — a quieter, calmer home.
That’s what we see most in Hervey Bay, but every home is different. Browse all our insulation services or ask for a quoteand we’ll tell you what yours needs.
Underfloor, done right
Underfloor insulation for Hervey Bay's high-set timber homes
Hervey Bay has plenty of older high-set timber homes — the classic Queenslander up on stumps, and the beach shacks around Scarness, Torquay and Point Vernon that have been lifted and built in underneath. If your home has a timber floor with open air moving around under it, that floor is one of the biggest comfort leaks in the house, and underfloor insulation is well worth doing. We fit custom-made polyester floor batts up snug between the joists from below — no fixings firing into the floor, just a clean, gap-free fill that stays put.
In winter, a bare timber floor over an open subfloor is cold underfoot and pulls the warmth straight out of your rooms — the YourHome guide (the Australian Government's own house guide) puts an uninsulated suspended timber floor at only about R0.25, which is next to nothing. In summer it works the other way: the cool air your air-conditioner pays for is the heaviest air in the room, so it sinks and literally falls out through the floorboards if there's nothing under there to hold it. Insulate the floor and you keep the warm in over winter and the cool in over summer — cooler in summer, warmer in winter, the same job we do up in your roof.
The other half of the story is coverage, and it's where doing it properly really pays. Gaps wreck a floor batt job the same way they wreck a ceiling — independent ICANZ testing (2024) shows that around 6% of gaps can roughly halve the effective R-value you paid for. That's why we measure and cut the poly batts to fit hard between every joist with no sag and no gaps. If your home is on a concrete slab — and a lot of the newer Eli Waters, Urraween and Kawungan estates are — then there's no subfloor to get at, so underfloor insulation isn't the answer for you, and we'll tell you that straight rather than sell you something that won't work. For a slab home, the money is far better spent topping up the ceiling.

Hervey Bay questions
Insulation in Hervey Bay — your questions, answered.
Do you actually service Hervey Bay, or just the bigger towns?
We service the whole Bay and the Fraser Coast — Pialba, Scarness, Torquay, Urangan, Point Vernon, Eli Waters, Kawungan, Urraween, Wondunna, Nikenbah, Booral, River Heads, Craignish, Dundowran, Toogoom, the lot, and across to Maryborough and Burrum Heads. We've insulated homes all through this region. Your home's comfort is my job, whether you're on the Esplanade or out at Sunshine Acres.
It's coastal — do I even need insulation in Hervey Bay?
You absolutely do, and for both seasons. Hervey Bay summers average around 30°C with sticky humidity near 61% in the afternoon (BoM 040405), and an uninsulated roof cavity turns into an oven that radiates that heat down into your living rooms all evening. Then in winter the airport has logged mornings down to -1.2°C — cellulose fibre insulation stops the summer heat pushing in through your roof cavity AND keeps your warmth in (cold out) through winter. Cooler in summer, warmer in winter.
What's the difference between the foreshore suburbs and out at Nikenbah or Booral?
The bay water keeps the foreshore suburbs — Torquay, Scarness, Pialba — milder day and night. Get inland of the water, out toward Nikenbah, Booral and the airport, and you'll cop hotter still afternoons and noticeably colder nights (the airport's record low is -1.2°C). It doesn't change the product, but it's a good reminder that 'coastal' doesn't mean you can skip insulating — those inland streets feel both extremes harder.
My place is up on stumps — can you insulate under the floor?
Yes, and it's well worth it on a high-set timber home. We fit custom-made polyester floor batts up snug between the joists from below — no fixings, no gaps. A bare timber floor over an open subfloor is only about R0.25 (YourHome), so it's a real comfort leak: cold underfoot in winter, and in summer the cool air your air-con pays for is heavy, so it sinks and falls straight out through the floorboards. If you're on a concrete slab instead, there's no subfloor to get at and we'll tell you so — the money's better spent in the ceiling.
Can you just top up the old insulation that's already in my roof?
Usually, yes — and it's the smart way to do it. We pump cellulose fibre straight over whatever's already up there; about 100mm adds roughly R3.0 over the top, fills all the gaps the old batts leave, and covers the timber joists (which are only about R1.5 themselves). You keep the value of the old insulation, and there's no ripping it out, no mess, no dump fees. We don't bother removing good product just to sell you new.
I've got downlights — is the insulation safe over them?
This is exactly why you want a trained installer. Old-style halogen and 240V downlights get very hot, and cellulose insulates so well it would trap that heat — so we never cover them. We shroud old lights with a poly guard keeping the 200mm clearance, and 300mm around flues. If you ever upgrade to modern LED IC-4 'cover-and-abut' lights, those are designed to be insulated right over. We sort all of this on the day so it's done right and safe.
How do I get a price — do you come out and measure first?
No need — we quote online, and the price we give you is a fixed price that doesn't get bumped up when we arrive. Tell us your address, roof type and roughly the area, and we'll do the rest. We only ever need to visit beforehand in the rare case some detail's missing. And we don't leave you chasing us — once you're booked, follow-up is our job, not yours.
