Use Case
Quick answer: Bunnings stocks small foam sandwich-panel offcuts that are handy for a patch or a tiny DIY box, but they are not full-height structural coolroom panels. For a cool room, freezer or insulated shed that has to actually hold temperature, you want proper 50–75mm EPS panels with cam-lock joints — cut to size and delivered across Adelaide.
What you actually get at Bunnings
Search “coolroom panel Bunnings” or “50mm coolroom panel Bunnings” and you’ll mostly find short insulated sandwich panels sold as single sheets. They’re fine for what they are, but there are limits:
- Sold as small individual sheets, not room-sized runs.
- Usually plain butt edges — no cam-lock or tongue-and-groove to lock panels together.
- No cutting-to-length, no channels, doors or hardware to finish a room.
- Limited thickness and R-value options for a true cold room or freezer.

When a Bunnings panel is fine — and when it isn’t
Fine for: a tiny insulated box, a pet or produce cooler, a quick repair, or a hobby project where temperature isn’t critical.
Not fine for: a walk-in cool room, a commercial fridge or freezer, a cafe or butcher fit-out, or an insulated shed. Without cam-lock joints the seams leak cold air, the compressor works overtime, and your power bill climbs. It also won’t satisfy a refrigeration installer signing off the job.

FAQ
Does Bunnings sell coolroom panels?
Bunnings sells small insulated sandwich-panel sheets, but not full structural coolroom panels with cam-lock joints, matching channels and doors. For a working cool room you need purpose-made panels.
How thick should a coolroom panel be?
50mm EPS suits most chillers; 75–100mm is better for freezers or hot Adelaide sheds where you want a higher R-value.
Can I get panels cut to size?
Yes. We cut EPS panels to length up to 6m so they arrive ready to lock together.
Need coolroom panels cut to size?
Skip the guesswork — get panels, channels and doors from an Adelaide coolroom specialist.
