Which EPS Panel 50mm Length Do You Need?
The EPS panel 50mm is available in 2.4m, 2.7m, 3m, 3.6m, 4.8m and 6m lengths. Choose based on your coolroom wall height:
- 2.4m — standard residential coolrooms, small commercial chillers, single-height walls
- 2.7m or 3m — commercial coolrooms with higher ceilings, hospitality fit-outs
- 3.6m–6m — large walk-in coolrooms, warehouse cold storage, roof panel applications

Frequently Asked Questions — EPS Panel 50mm
What is the R-value of a 50mm EPS panel?
A 16 kg/m³ EPS core at 50mm typically achieves an R-value of approximately R1.25–R1.4 (thermal resistance). For sub-zero freezer applications, we recommend upgrading to the 75mm EPS panel for better thermal performance.
How many EPS panel 50mm panels do I need for my coolroom?
Divide your total wall area (perimeter × wall height) by the panel coverage width (1.15m). For example, a 3m × 3m × 2.4m coolroom has a wall area of approximately 28.8m² — you’d need about 25 panels. Contact us and we’ll calculate for you.
Is the EPS panel 50mm suitable for freezer rooms?
The 50mm panel is ideal for standard chiller applications (+2°C to +10°C). For freezer rooms (sub-zero), we recommend the 75mm EPS panel for improved insulation performance.
Can I cut EPS panels on site?
Yes — EPS Z-lock panels can be cut with a circular saw or jigsaw. See our guide to cutting coolroom panels for tips and blade recommendations.
What accessories do I need with the EPS panel 50mm?
For a complete installation you’ll need corner channels, C-channels, L-channels, T-channels and appropriate fasteners. Browse our panel accessories for a full range.
