Where Are 75mm Coolroom Panels Used?
75mm panels are specified when performance and energy efficiency matter most.
🥩 Butcher Shops
High door-opening frequency and near-0°C storage demands make 75mm the preferred thickness for meat retail cool rooms.
🏭 Large Cold Storage
Larger rooms with greater internal volume benefit from 75mm insulation to maintain consistent temperatures and reduce compressor runtime.
☀️ Hot Ambient Environments
South Australian summers push ambient temperatures above 40°C. 75mm panels significantly reduce heat ingress and running costs.
❄️ Near-Freezer Applications
For cool rooms operating at −5 to −10°C, 75mm EPS provides the thermal resistance needed without stepping up to PIR/PU panels.
🍺 Brewery & Beverage
Precise temperature control for fermentation and storage rooms benefits from the higher R-value of 75mm EPS construction.
💊 Pharmaceutical Storage
Temperature-sensitive medication storage at 2–8°C requires reliable, consistent insulation — 75mm delivers the margin needed.
FAQ — 75mm Coolroom Panels Australia
Common questions from builders, food businesses and cold-chain operators.
When should I use 75mm coolroom panels instead of 50mm?
Choose 75mm when you have high door-opening frequency (butcher shops), a hot ambient environment (SA summers above 40°C), near-freezer temperatures (−5 to −10°C), or a large room where energy efficiency is a priority. The higher upfront cost is offset by lower long-term running costs.
What is the R-value of a 75mm EPS panel?
Cool Room Master’s 75mm EPS Z-Lock panels have an R-value of approximately 2.08 m²·K/W — 50% better than 50mm panels (R≈1.39) and more than double the 35mm option (R≈0.96).
Can 75mm coolroom panels be cut to custom lengths?
Yes — cut-to-length is standard. Provide your room dimensions and we will cut 75mm panels to spec, minimising waste and installation time on site.
How much do 75mm coolroom panels cost in Australia?
75mm EPS Z-Lock panels are priced higher than 50mm due to the additional material. Visit our online shop for current pricing or contact us for a project quote with delivery.
