The EPS panel 35mm Z-lock is a high-performance insulated coolroom wall panel available in 3m length. Designed for compact coolroom builds and small cool rooms, this EPS Z-lock panel offers reliable thermal performance, easy installation and tight panel-to-panel sealing. In stock in Adelaide with fast Australia-wide delivery.
Overview
The 35mm coolroom panel (3m, Z-Lock) delivers the most wall coverage per panel in the 35mm range — the smart choice when you’re fitting a large cool room or high-bay chiller and want to minimise joins. At R ~0.88 m²K/W, it maintains 0°C to +8°C reliably in commercial environments. The 3m length covers floor-to-ceiling in one run on most installations, reducing horizontal seams and the air infiltration risk that comes with them.
Key Features
- 3m length — maximum coverage: fewer panels, fewer joins, faster install on large footprint rooms.
- Single-run floor-to-ceiling: eliminates horizontal mid-wall joints — better airtightness and hygiene.
- Z-Lock join: interlocking profile seals adjacent panels without exposed fixings.
- 950mm cover width: 35mm profile — plan panel count on 950mm coverage per run.
- Lightest 3m option: 35mm EPS keeps weight low even at full length — manageable on-site.

More Coverage, Fewer Joins
At 3m, this panel eliminates horizontal joins in most standard cool room heights — reducing both installation time and long-term air infiltration risk at seams. It’s the most efficient panel in the 35mm range for large projects. Browse the full 35mm range to mix lengths for returns and corner panels. Need sub-zero performance? See our 75mm range.
Installation Notes
- Confirm your cool room’s target temperature — 35mm EPS suits 0°C to +8°C applications.
- 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.
- 35mm panels can be cut on-site with a circular saw or hand saw — lightweight and easy to manage.
FAQs
Why choose 3m over 2.4m or 2.7m panels?
3m panels cover floor-to-ceiling in a single run for most commercial cool room heights, eliminating horizontal joints mid-wall. Fewer joints means a faster install, better airtightness, and a cleaner surface that’s easier to maintain in food environments.
Is 35mm thick enough for a large commercial cool room?
35mm EPS (R ~0.88) suits large cool rooms holding 0°C to +8°C. For high-ambient sites or rooms requiring tighter temperature control, consider 50mm or 75mm. We’re happy to advise on the right spec for your project.
What is the cover width of the 3m panel?
950mm per panel — the same as all 35mm Z-Lock panels. For a room wall that is 5.7m wide, you’d need 6 panels (6 × 950mm = 5,700mm). We can also supply cut-to-length for non-standard dimensions.
Can I order in bulk for a large project?
Yes — we supply trade quantities and offer volume pricing for contractors and project buyers. Contact us with your panel count, lengths required, and project timeline for a quote.
Do you offer cut-to-length on 3m panels?
Yes — if your wall height is non-standard, we can cut panels to your specified length. Contact us to discuss cut-to-length pricing and lead times.
