Overview
The 75mm insulated coolroom panel (3m length, Z-Lock) delivers full-height coverage for large commercial cool rooms and freezer builds in a single panel run. At R ~2.08 m²K/W, the 16 kg/m³ EPS core and 0.45mm steel skins maintain stable sub-zero temperatures while keeping energy costs low. The Z-Lock profile joins wall runs without exposed fasteners — critical for hygiene-sensitive food environments.
Key Features
- 3m length: covers high-bay cool rooms in one panel — no horizontal joins mid-wall.
- R ~2.08 m²K/W insulation: rated for cool rooms and freezers down to −18°C.
- Z-Lock join: no exposed fixings — clean, hygienic wall surface throughout.
- 1,150mm cover width: consistent with full 75mm Z-Lock range.

Built for Larger Cool Room Projects
The 3m panel is the preferred choice for high-bay cold rooms and large-footprint freezer builds where mid-wall joints are undesirable. Combine with shorter panels from the 75mm range for returns and corners. Customise-to-length service available for non-standard heights. Adelaide stock — contact us for volume pricing.
Installation Notes
- Ensure substrate is plumb before starting the first panel run.
- Engage Z-Lock fully along each run — a rubber mallet helps seat tight joins.
- Seal all junctions (corners, floor/ceiling) with closed-cell foam tape for airtightness.
- Use cool room rated trims and fasteners at perimeter.
FAQs
When should I use 3m panels instead of shorter lengths?
Use 3m panels when your wall height is 2.8–3m and you want to avoid a horizontal mid-wall joint. A single-panel height wall is stronger, more airtight, and easier to clean — important for food-grade rooms.
Is 75mm EPS sufficient for a large commercial freezer?
75mm EPS (R ~2.08) is suitable for cool rooms and light freezers to −18°C. For industrial deep-freeze below −18°C or high-ambient-temperature sites, consider 100mm EPS or PIR panels. Contact us for a specification recommendation.
What does Z-Lock mean for insulated panels?
Z-Lock is a machined tongue-and-groove profile on each panel edge. It mechanically locks adjacent panels together for a tight, gap-free join that resists air infiltration — without surface-mounted screws or clips that create hygiene traps.
What is the cover width of the 3m panel?
1,150mm, the same as all panels in the 75mm Z-Lock range. This lets you combine 2.4m, 2.7m, and 3m panels on the same project with consistent coverage.
Can I get a volume discount on 3m insulated coolroom panels?
Yes — we offer volume pricing for trade and contractor orders. Contact us with your panel count and project timeline for a quote.
