Australian homeowners, renovators and investors are upgrading sheds and garages to add value and weather protection. The right cladding board—whether Colorbond steel, external cladding sheets, timber weatherboard profiles or insulated panel cladding—can lift street appeal and cut maintenance for decades. Below is a practical, council-ready guide written for local conditions.
What is a cladding board—and why it matters on sheds?
Cladding board is the external skin that shields your shed, carport or garage from sun, wind and rain. In Australia, the most common options are:
- Colorbond steel exterior cladding sheets (ribbed profiles for strength)
- Zincalume steel cladding sheet (plain metallic finish)
- Insulated panel cladding (rigid foam core “external panel” with steel skins)
- Timber weatherboard cladding (horizontal cladding or vertical weatherboard styles)
- Fibre cement boards, V-groove board external and other facade panels
On a shed, cladding drives durability, wind performance, condensation control and appearance—especially if you want your outbuilding to match the main dwelling with white weatherboard or modern house facade panels.
What are the best shed materials for Perth’s climate?
Perth’s hot summers, UV and coastal salts demand heat-reflective colours and strong corrosion resistance.
Colorbond vs Zincalume — which is better for WA conditions?
| Feature | Colorbond Steel | Zincalume Steel |
|---|---|---|
| Corrosion resistance | Excellent; choose Colorbond Ultra for coastal (within ~200–400 m of surf) | Very good; avoid splash zones and very close marine exposure |
| Colour & aesthetics | Wide palette; matches modern homes and custom Colorbond garages in Perth | Metallic silver-grey only |
| Heat management | Cooler colours reflect more heat; add insulation for best results | Reflective finish; still benefits from insulation |
| Warranty | Strong warranties when installed to spec | Strong warranties when installed to spec |
| Price | Higher | More affordable |
| Best for | Premium look, coastal, matching home colours | Budget-friendly rural sheds in NSW and WA inland |
Pro Tip: Did you know using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer? Pair light Colorbond colours with roof insulation and whirlybirds for a noticeable comfort gain.
Cladding profiles and styles (for sheds and house-matching)
- Ribbed steel cladding profiles — high strength-to-weight for wind-rated sheds (vertical or horizontal cladding depending on look)
- Vertical weatherboard — contemporary lines to match modern facade panels
- Horizontal weather boards — timeless style; available as timber weather boards or fibre cement weatherboard profiles
- V groove board external — crisp shadow lines; popular in coastal designs
- Insulated panel cladding — clean architectural finish with built-in thermal performance
- Fibre cement and house facade panels — paintable “white weatherboard” looks without timber upkeep
Note: “Masonite cladding” (hardboard) was used historically. For today’s sheds, fibre cement or treated timber weatherboard cladding is preferred for moisture resistance and compliance. If you want timber weatherboard cladding, specify treated, primed boards and a robust paint system.
Choose cladding by region and shed use-case
- Steel sheds Perth — prioritise Colorbond Ultra near the coast, sarking plus insulation, and corrosion-resistant fixings
- Custom carports Melbourne — panel cladding or Colorbond to match the home; consider snow/wind in outer metro
- Rural sheds NSW — Zincalume cladding sheet for value; add girts and bracing for wide bays and farm machinery storage
- cyclone-rated sheds QLD — Region C/D design with thicker cladding, closer fastener spacing and engineered connections
- Farm machinery storage — high-clearance bays, deep eaves, durable exterior cladding sheets for knock resistance
- Granny-flat or studio conversions — insulated external panel systems for thermal and acoustic comfort
Wind-rated sheds for cyclonic and high-wind areas
Design and certification must follow AS/NZS 1170.2 for wind actions, with N or C category ratings depending on region and terrain. This influences cladding thickness, span, screw type and spacing.
- Non-cyclonic (N2–N4): common across VIC/NSW/SA inland
- Cyclonic (C1–C4): coastal QLD, northern WA
- Coastal exposure: specify marine-grade coatings and stainless or class 4 fasteners
Added 2024 WA wind-rating compliance notes: In WA, verify your wind region (A, B, C or D) and terrain category before ordering. Councils increasingly require an engineer’s certificate showing the cladding profile, base metal thickness (BMT), fastener type and fixing pattern for the nominated wind class.
Bushfire (BAL) and shed cladding
For bushfire-prone areas, select BAL-compliant cladding and ember-resistant detailing per AS 3959. Steel cladding and fibre cement are common solutions; seal eaves and add ember guards to vents.
How to get council approval for your custom shed in WA (and other states)
Most sheds over small exemption thresholds need approval. For council-approved sheds WA (and similar processes elsewhere):
- Site plan: setbacks, sewer/water lines, stormwater management
- Certified drawings: elevations, cladding profiles, door/window schedules
- Engineer certification: wind region, tie-down, slab design, cladding BMT and fastener schedule
- Energy/condensation notes: insulation, sarking, ventilation
- Lodgement: pay fees, respond to RFI; allow 2–6 weeks depending on council
DIY shed kits vs custom-built sheds
DIY shed kits
- Pros: cost-effective, fast to deliver, perfect for DIY shed kits on flat sites
- Cons: limited customisation, you manage approvals and compliance
Custom-built sheds
- Pros: tailored design (e.g., custom Colorbond garages Perth), easier approvals, integrated slab and install
- Cons: higher cost, longer lead times
Budget tip: For affordable carports for Australian homes, choose standard spans and common Colorbond colours to reduce price and lead time.
Real build examples (2024–2025)
Perth coastal double garage

- Compare quotes: Colorbond vs Zincalume comparison, install inclusions, warranties
FAQs about cladding board for sheds
Is timber weatherboard cladding okay on a shed?
Yes, with proper detailing: breathable sarking, cavity battens, end-sealing and paint. For low-maintenance, fibre cement weather boards or steel are easier.
What’s the most waterproof cladding?
Properly installed steel exterior cladding sheets with sealed laps and flashings are highly weatherproof. Insulated panel cladding offers excellent water deflection and fewer joints.
Can I get weatherboards for sale to match my house?
Yes. Many suppliers stock weatherboard profiles, including V-groove board external and pre-primed “white weatherboard” options.
What about “cladding cladding” terms I see online?
They usually refer to cladding options in general—cladding board, cladding sheet and panel cladding systems for exteriors.
Where to buy cladding boards and exterior cladding sheets
Look for Australian-made steel from reputable suppliers and registered builders. Check availability of:
- Colorbond and Zincalume cladding sheet profiles
- Insulated external panel systems
- Timber weather boards and fibre cement weatherboard profiles
Installation tips and maintenance
- Fasteners: Use class 4 coated or stainless steel in coastal zones; match metals to avoid galvanic corrosion
- Cut edges: Use factory cuts where possible; treat cuts as per manufacturer
- Cleaning: Rinse coastal salt quarterly; clean sheltered areas to maintain warranty
- Condensation: Use sarking, ventilation and insulation to control moisture
Sustainability and performance
- Steel is recyclable; many Colorbond and Zincalume products contain recycled content
- Light colours + insulation cut cooling loads; consider roof ventilation
- Specify durable materials to reduce lifecycle maintenance and waste
Local standards, climate and references
- Design to AS/NZS 1170.2 (wind actions) and AS 3959 (BAL) as applicable
- Use Bureau of Meteorology wind/climate data when assessing exposure
- Follow manufacturer installation manuals for cladding profiles and fasteners
