Platinum “R” Floor NSW

Insulated Subfloor Panels for New South Wales Builders

Platinum “R” Floor is a Structural Insulated Panel System (SIPS) that combines structural plywood flooring and insulation in a single panel, so a suspended floor reaches both its structural and its thermal performance in one install rather than three stages. Platinum Timber & Ply manufactures it in Queensland and supplies it Australia wide, including every building region in New South Wales.

New South Wales asks a lot of a floor. The same panel serves a humid Northern Rivers build, a Sydney infill site and cold tableland country, specified to the R-value the design calls for.

  • An insulated subfloor system: structural plywood skins bonded to an insulated core in one panel.
  • Manufactured in Queensland, supplied Australia wide, including all of New South Wales.
  • Four published panel R-values, so the floor can be specified to the thermal target the design needs.
  • Suits any residential floor, including modular and prefabricated builds, wet areas and upper storeys.
  • Termite treated panels can be used throughout Australia with no restriction by geographical location.
  • Freight and timing are confirmed per project. Talk to the Platinum Timber & Ply team about yours.

Why New South Wales Builders Choose Platinum “R” Floor

On a suspended floor the subfloor is one of the few places left to add thermal performance once the glazing and the orientation are settled, and in New South Wales every new home has an energy rating to meet. Building the insulation into the structural layer means it is there from the day the floor goes down.

  • Thermal performance built into the floor. The insulation sits inside the panel, so there is no separate underfloor batt stage to schedule, inspect or replace later, the same principle behind our insulated subfloor systems.
  • Four R-values to specify against. R1.2, R1.5, R2.0 and R2.5, which matters across a state running from warm coast to cold tablelands.
  • Fewer stages on site. One panel covers the sheeting and the insulation in a single structural insulated panel, shortening the run to lock-up.
  • Wet area set downs without joist modification. A fibre cement flashing strip between the panel and the wet area flooring creates the wet area set down, so there is no notching or dropping of joists.
  • Factory-manufactured consistency. Every panel arrives to the same tolerance, the factory-to-floor precision that makes interstate supply predictable to program and price.

Made in Queensland, Supplied Across New South Wales

Platinum “R” Floor is manufactured in Queensland and supplied Australia wide. There is one plant, one specification and one set of certifications, so a job in Albury gets the same panel as a job in Logan.

The panels are 100% Australian made and certified by Australian Made Campaign Limited. The timber carries Responsible Wood Chain of Custody certification under AS 4708, endorsed internationally through PEFC. Because the supply chain is domestic rather than dependent on imported panel stock, that certification travels with the panel to any state.

Freight and delivery timing are confirmed per project, since they depend on where the job is and how much panel it needs. Talk to the team when you are pricing the floor and they will confirm both for your site, along with anything you need to know about unloading. Panels come in standard sheet sizes, and per the builder feedback published on the Platinum “R” Floor product page, a 64mm sheet is comfortably handled by two people.

Built for New South Wales Building Conditions

New South Wales covers more ground, in every sense, than any state we currently have a page for, and each of the conditions below shapes how the floor is specified.

Cold Country

Through the tablelands, the Southern Highlands and the Snowy Mountains, heat lost downward through an uninsulated suspended floor is lost for the whole season, and the thicker panels are specified for exactly this.

Reactive Ground and Sloping Sites

Reactive clay is common through western Sydney, the Hunter and parts of the Riverina, and a suspended floor over standard framing is one of the usual answers, with joist size and spacing set by the project engineer whether the frame is timber or steel.

Elevated and Flood-Affected Builds

Platinum “R” Floor is regularly specified for elevated and multi-storey homes, which matters on the Northern Rivers and the Hawkesbury-Nepean floodplain where elevated construction is common.

Wet Areas and Upper Storeys

The panel suits bathrooms, laundries and upper-level floors as readily as ground-level suspended floors, so one product covers the whole floor plan.

Modular, Transportable and Prefabricated

Regional New South Wales is a strong market for transportable and modular housing, and a factory-cut panel suits factory-based assembly.

Bushfire-Prone Land

Much of regional NSW is mapped as bush fire prone, and subfloor enclosure and materials form part of a bushfire assessment, so contact the Platinum Timber & Ply team about specifying Platinum “R” Floor for your site’s rating and your certifier’s requirements.

Supporting New South Wales Builders from Concept to Completion

A conventional suspended floor reaches its finished state through several separate stages, each with a trade, an inspection and a weather window attached. An insulated structural panel collapses most of that into one: structural plywood skins top and bottom, an insulated core integral to the panel, thermal continuity that arrives in position rather than depending on install quality, and a wet area set down formed with a flashing strip instead of modified joists.

Platinum “R” Floor is published as going beyond Australian Standard load requirements, up to four times stronger than particleboard, while also delivering the thermal insulation. On a job three states from the plant, that consistency is the point: what is quoted is what turns up.

We supply builders, architects, building designers and modular manufacturers across New South Wales from our Queensland manufacturing base. Delivery is arranged per project, so contact the team with your site address.

Frequently Asked Questions


Does Platinum Timber & Ply supply New South Wales?

Yes. Platinum “R” Floor is manufactured in Queensland by Platinum Timber & Ply and supplied Australia wide, including every building region in New South Wales from the Tweed to the Riverina. There is no separate NSW product and no imported substitute, so a NSW builder receives the same certified panel as a Queensland one. Contact the Platinum Timber & Ply team with your site address and panel quantity and they will confirm freight and timing.

Where is Platinum “R” Floor manufactured?

Platinum “R” Floor is manufactured in Queensland by Platinum Timber & Ply and is 100% Australian made, certified by Australian Made Campaign Limited. The panels are built from Australian production structural plywood skins over an Australian manufactured foam core, and the timber carries Responsible Wood Chain of Custody certification under AS 4708. Because the supply chain is domestic rather than reliant on imported panel stock, the certification and the specification are the same wherever the panels are delivered.

How is freight to New South Wales handled?

Freight and delivery timing are confirmed per project, because both depend on how much panel the job needs and where it is going. A Tweed Heads delivery and a Wagga Wagga delivery are not the same job, so Platinum Timber & Ply confirms the arrangement for your site rather than publishing a flat figure. Ask the team when you are pricing the floor and they will sort it out with your panel quote.

Which Platinum “R” Floor R-value suits a New South Wales build?

Platinum “R” Floor is published in four panel R-values: R1.2 at 54mm, R1.5 at 64mm, R2.0 at 84mm and R2.5 at 99mm. New South Wales runs from warm coast to cold tableland and alpine country, so the right panel for a Sydney build is not necessarily the right one for the Snowy Mountains. Your energy assessor sets the target and the Platinum Timber & Ply team can match a panel to it.

Can Platinum “R” Floor be used in bathrooms and wet areas?

Yes. Platinum “R” Floor suits wet areas as readily as the rest of the floor, and the set down is formed with a fibre cement flashing strip between the panel and the wet area flooring rather than by notching or lowering joists. That means bathrooms, laundries and kitchens are handled with the same panel as the rest of the floor plan, which is one of the reasons Platinum Timber & Ply sees it specified across whole builds rather than in isolated areas.

Can Platinum “R” Floor be used in regional and alpine New South Wales?

Yes. Platinum “R” Floor panels are termite treated and can be used throughout Australia with no restriction by geographical location, and the thicker R2.0 and R2.5 panels are there precisely for the cold tableland and alpine country through the Southern Highlands and the Snowy Mountains. Platinum Timber & Ply supplies regional New South Wales on the same project-by-project basis as the capital cities, so contact the team with your delivery point.

Trusted by New South Wales Builders & Industry Professionals

New South Wales asks one floor system to work from a humid North Coast build to an alpine one. Platinum “R” Floor answers with one certified Australian-made panel, specified to the thermal performance each site needs, manufactured in Queensland and delivered anywhere in the state.

Contact the Platinum Timber & Ply team about your project. Being made in one state does not make it a Queensland product. It makes it a consistent one.
