FAQ — 35mm Coolroom Panels Australia
What are 35mm coolroom panels best used for?
35mm panels suit light-duty applications — partitions, modular offices, portable buildings and chillers at 0–8°C with low traffic. For most commercial cool rooms, we recommend 50mm or 75mm for better thermal performance.
What is the R-value of a 35mm EPS panel?
R-value ≈ 0.96 m²·K/W (U-value ≈ 1.04 W/m²·K). This is the lowest in our EPS range — suitable for mild temperature control only. For commercial cool rooms, 50mm (R≈1.39) is the minimum recommended thickness.
Can 35mm panels be cut to custom lengths?
Yes — customise-to-length is standard. Provide your room dimensions and we will cut panels to spec, minimising waste and speeding up installation.
How much do 35mm coolroom panels cost?
35mm EPS Z-Lock panels are the most affordable in our range. Visit our online shop for current pricing or contact us for a project quote.
