Is the calculator cost a firm quote?

No. It is an indicative supply-only band scaled from a real published EPS panel price by core and thickness. Firm pricing depends on exact panel lengths, doors, delivery and lead time.

Panel counts use each side length ÷ cover width (rounded up); roof panels use 1.0 m cover with a slope factor. Costs are supply-only from real published EPS $/m². Exact schedule depends on layout, panel length and openings.

How this estimate works

Numbers you can plan and order from

Panel countPerimeter and ceiling span divided by panel cover width (1150 mm standard), rounded up.

Live R-valueThickness ÷ core λ (EPS 0.036, Rockwool 0.040, PIR 0.022 W/m·K) — PIR gives the highest R.

Accessory metresCove, corner channel and ceiling angle by perimeter and height, plus sealant and fixings.

Itemised costPanels at real EPS $/m² by thickness, plus door package ($599 / $499) and channel trims — a supply-only total, ex GST.

How many panels do I need for a cool room?

Add the wall run (perimeter) and the ceiling span, then divide by the panel cover width — 1150 mm is standard. This calculator does it for you: set length, width and height and it returns wall panels, roof panels and a total, with an adjustable waste allowance so you never under-order.

Which core should I choose — EPS, PIR or Rockwool?

EPS is the value choice for most chillers and dry stores. PIR delivers the highest R-value per millimetre (100 mm PIR is the freezer standard) and is the most expensive core. Rockwool is chosen where non-combustible fire performance matters; it sits between EPS and PIR on cost. Switch cores in the calculator to compare R-value and indicative cost instantly.

What does the R-value mean here?

R-value is thermal resistance: panel thickness in metres divided by the core’s thermal conductivity (λ). Higher is better. For example 50 mm EPS ≈ R1.39, while 50 mm PIR ≈ R2.27 for the same thickness — that’s why freezers use thick PIR.

Is the cost a firm quote?

No. It’s a supply-only estimate: panels priced at real published EPS $/m² by thickness (35 mm $32, 50 mm $42, 75 mm $55), plus your door package ($599 or $499) and channel trims. PIR and Rockwool figures are indicative — the EPS rate × a core factor (PIR is the most expensive core, Rockwool sits between). Excludes GST, delivery and install — use “Copy summary” and send it for a firm quote.
