Composite cladding Perth

What is composite cladding?

Composite cladding is a wall board made from wood fibre and high-density polyethylene, extruded into a profile and, in the better products, wrapped in a protective cap. The cap is the part that matters in Perth: it is what stops the board fading under UV, staining from salt air and holding moisture. A capped composite never needs painting, oiling or sanding, which is the whole reason a builder specifies it over timber on a west-facing wall.

Three composite systems come through Integrity, and they are not interchangeable. NewTechWood is the volume choice with the widest colour range and a 25-year residential warranty. WoodEvo is the one with a BAL29 rating. Millboard is the premium mineral board for the project where the client has seen it in a magazine. All three come with their own clips and trims, and all three are priced specific to your job.

NewTechWood Shadowline and Castellation cladding

NewTechWood boards are made from 95% recycled materials, a mix of hard and soft wood fibres and HDPE, with full protective capping on every board. NewTechWood's own claims for the cap: no warping or rotting from moisture, no splitting or fading from UV, no mould. Two cladding profiles, Shadowline and Castellation, in NewTechWood's multi-chromatic timber tones including Ipe, Teak, Aged Wood and Blackbutt. The cladding is CodeMark certified and carries a 25-year limited residential warranty.

The honest line on fire: NewTechWood states that its cladding does not have a BAL bushfire rating. On a BAL-rated lot, put it on the elevations that do not need it and use Knotwood or stone on the ones that do. We will tell you that before you order, not after the certifier does.

NewTechWood's range

WoodEvo castellated composite cladding

WoodEvo is an Australian composite brand based in Melbourne, and its cladding is the one composite in our range with a published BAL29 rating. A castellated wood-plastic profile, purpose-built for Australian conditions, UV colour-fast, with a 12-year warranty. It is the answer when the lot is BAL-rated but the client still wants a timber look on the main elevations.

WoodEvo's range

Millboard Envello cladding

Millboard is designed and manufactured in the UK and is wood-free: each board is 38% recycled content, including limestone diverted from landfill, bonded in a polymer resin and moulded from real timber so the grain is not a repeating print. The cladding range is Envello Shadow Line+, Envello Board & Batten+ and Envello Décor. It reaches Australia through Millboard's appointed importer and is supplied through us in Perth. Tell us early: it is an imported board and the order is planned around that.

Millboard's range

Aluminium cladding Perth

Timber-look aluminium cladding Perth

When the wall has to be non-combustible, timber and most composites are out and the choice becomes aluminium. Knotwood is the timber-look aluminium system we supply: extruded solid aluminium profiles with no polymer core (it is not an aluminium composite panel), finished in a sublimated timber grain or a solid architectural powder coat. Knotwood's published test data has it not deemed combustible when tested to AS 1530.1, with a Spread of Flame Index of 0 and a Smoke Developed Index of 4 to AS/NZS 1530.3 and an AS 5637.1 Group 1 classification, and the range holds CodeMark certification. Ask for the current certificate and test report with your quote so the certifier has them before the boards arrive. Knotwood states it is made on the Gold Coast, 100% Australian owned and operated, and ISO 9001 certified.

Five cladding profiles: Shadow Line, V Line, Weatherboard, Castellated (a 150mm board in 6500mm lengths) and Fixed Gap, all on Knotwood's tab-lock concealed fixing so there are no visible fasteners on the finished face, and all sharing one finish range so a castellated feature panel can sit beside a flatter profile on the same facade. The same finishes run across Knotwood's battens, screens, louvres and decking, which is how a facade, a soffit and a screen end up matching on one building.

Where it goes: commercial and multi-residential facades (Knotwood's published position is that the Group 1 classification supports Type A and Type B construction, subject to project-specific assessment), soffits and balcony ceilings, recladding over a sound existing facade, and houses on bushfire-prone lots within the limits of the assessment. Knotwood cites a CSIRO assessment of the cladding as suitable where AS 3959 requires non-combustible material up to BAL-19, with a separate wall-system assessment above that, so ask for the report that matches the BAL on your lot before it is specified. The powder coat carries a standard 15-year warranty, up to 25 years on selected finishes, and it has to be registered to take effect.

Bushfire-prone lots and non-combustible walls: which cladding to spec

Perth's hills and its urban fringe carry BAL ratings, and commercial building classes carry non-combustibility rules of their own, so this is the question we get asked most on cladding. The answer is per product, not per material, and it is not always the one people expect.

Knotwood aluminium: not deemed combustible to AS 1530.1, AS 5637.1 Group 1 and CodeMark certified, per Knotwood's published data. CSIRO's assessment covers up to BAL-19; confirm the wall system for higher BALs. The one to reach for when the certifier wants a test report rather than a brochure.
WoodEvo composite: rated to BAL29 by the manufacturer. The timber-look composite for a BAL29 lot.
NewTechWood composite: no BAL rating, in NewTechWood's own words. Use it on the elevations the BAL assessment does not cover.
McMonagle natural stone: stone does not burn. Confirm the fixing system and substrate meet the rating.
Millboard: check Millboard's fire and safety data for the application before it goes on a rated wall.

Put the BAL level or the wall type on the enquiry and we price the system that passes. Ask for the manufacturer's test report with the quote and the certifier has it before the boards arrive.

Stone cladding Perth

Natural stone cladding Perth, quarried in Donegal

Most stone cladding sold in Perth is a manufactured veneer or a reconstituted panel. McMonagle Stone is the other thing: natural stone cut from four quarries in south-west Donegal, Ireland, by a family business that has been quarrying for three generations and more than 50 years. Integrity brings it into Perth for feature walls, entries, piers and the elevation that has to look like nothing else on the street.

The two stones to know are Donegal Quartzite, a hard, gold-toned stone that is machined for cladding and walling, and Mountcharles Sandstone, supplied as machined rubble for walling and as paving. Both come in cladding, walling and paving formats, so the entry wall, the garden walls and the path can come off the same quarry. McMonagle is listed on the Ethical Stone Register under the Stone Federation Great Britain.

Stone is heavy and it is shipped, so it is the one system on this page to raise at design stage rather than at frame stage. Tell us the wall and the format and we plan the order around the shipping window.

Weatherboards, fibre cement and timber

The rest of the cladding spec

Not every elevation wants composite, aluminium or stone. Weatherboards, fibre cement sheet and boards, and timber cladding still turn up on most Perth house lots, and they are on the same account: we source the trade brands your spec calls for through the merchants we buy from, and put them on the one order with the rest of the facade. If a brand is not on this page, ask. The point of one account for the whole build is that you do not have to ring a fourth supplier for the weatherboards.

What to order with the boards

The cladding order is never just the boards

The part that goes wrong on site is the accessories: the starter clip that was not ordered, the corner trim in the wrong colour, the wall wrap that turned up a week late. Every system below goes on the list with its boards, so the wall goes up in one visit.

Battens, ventilation and wall wrap

The drained cavity behind the cladding

Composite and aluminium cladding are not fixed flat to the frame. They sit on a batten or clip system that holds the boards off the wall, over a vapour-permeable membrane, so that any water that gets past the joints drains down and out, and air moves behind the boards to dry them. NewTechWood's profiles and clips are designed to hold that gap and to let the boards expand and contract with the heat, which they do, so the gap and the clip spacing in the installation guide are not optional.

What that means for the order: the wrap, the battens, the clips and the trims are part of the cladding, not extras. It is why we put them on the same list as the boards, and why we ask which way the boards run before we price it, because vertical and horizontal cavities are battened differently.

How it works

How to order cladding for a build

Three steps, one point of contact from the first email to the truck.

01
Send the area and the system
Square metres of wall, the profile or brand you are pricing, the colour, and whether any of it is on a BAL-rated lot or a commercial wall type. If you are still choosing, tell us the look and the building class and we suggest the system that fits.
02
One price, boards and accessories together
Boards, clips or battens, starter and finishing trims, corners and colour-matched fixings on one list, priced as one order by one person. Nothing to reconcile between a board quote and a trim quote.
03
Delivered to site, to programme
Delivered across Perth, Western Australia to suit your programme, all five brands from the one account. Need it installed? We link you in with install teams we work with.

We supply across Perth, Western Australia, delivered to site, with a sister operation in Queensland. Residential and commercial builders are most of the order book. Homeowners and self-builders can order the same systems, and if you would rather not fit it yourself, we link you in with install teams we work with.

Straight answers

Cladding in Perth, the questions we get asked

If yours is not here, send it through and you will get an answer from the person who prices the orders.

Where can I buy exterior wall cladding in Perth?

Integrity Building Materials supplies exterior cladding across Perth, delivered to site rather than collected from a showroom: NewTechWood, WoodEvo and Millboard composite, Knotwood timber-look aluminium and McMonagle natural stone. Send the wall area and the system you are after and it comes back as one price with the accessories on the list.

Is composite cladding fire-resistant or BAL-rated?

It depends on the product, and the honest answer is not always yes. WoodEvo composite cladding is rated to BAL29. NewTechWood states that its cladding does not carry a BAL bushfire rating. Where the lot is BAL-rated or the wall has to be non-combustible, Knotwood aluminium is the system to look at: extruded solid aluminium, which Knotwood publishes as not deemed combustible when tested to AS 1530.1 and CodeMark certified. CSIRO's assessment covers non-combustible requirements up to BAL-19, so for a higher BAL ask us for the wall-system assessment with the quote.

Do I need a membrane under composite cladding?

Composite and aluminium cladding go on over a vapour-permeable wall wrap and a batten or clip system that holds the boards off the wall, so the cavity behind them drains and breathes. Follow the manufacturer's installation guide for the exact build-up. We supply the wrap and battens on the same order as the boards.

How much does cladding cost per square metre in Perth?

It comes down to the system (aluminium and stone sit above composite), the profile, the colour, the accessories the wall needs and how much of it there is. We do not publish a rate, because every wall is different and it is priced specific to your job. Send the area and the system and you get a real number for the whole job, not a rate that changes once the trims are added.

What are the disadvantages of composite cladding?

Composite boards move with heat, so they need the clip system and expansion gaps the manufacturer specifies. Some composites have no BAL rating, so they are not the answer on a bushfire-prone lot. And an uncapped board will fade and stain, which is why the brands we supply are capped or mineral-based. Get those three things right and it outlasts painted timber with no oiling.

Can I mix cladding brands on one job?

Yes, and it is common: a composite on the main elevations, Knotwood on the soffits and the commercial wall that has to be non-combustible, stone on the entry feature wall. Because all five brands come through the one account, the whole facade is one order and one delivery.

Do you install cladding?

Supply only. We price and deliver the boards, battens, trims and fixings. If the job needs fitting, we link you in with install teams we work with. Commercial site hoarding is the only thing Integrity supplies and installs itself.

Is composite cladding suitable for Perth's climate?

Capped composite is built for exactly this climate. The capping is what stops UV fading and salt staining, and a board that never needs painting or oiling is worth having on a west-facing wall in February. Pick a colour with the sun in mind, dark boards run hotter, and use the ventilated cavity the system is designed for.
