Typical published ranges; confirm per grade. At the low end what matters is toughness — PC absorbs impact at -40 °C, which is the core value in cold stores and cold-climate outdoor work. At the high end what matters is rigidity — dimensional stability near 100 °C is what allows use on exposed roofs and near equipment.
A dark panel in strong summer sun can reach 70–85 °C at the surface and remains within range. Cold stores run at -18 °C to -35 °C without embrittlement. Below -30 °C outdoors, take care at installation: the sheet hardens and cold bending can crack it.
That last point matters — service temperature and installation temperature are different things. A -40 °C rating does not mean you can cold-form it on site at -30 °C.
Heat plus UV. Elevated temperature accelerates UV-driven ageing, so the same panel ages faster in hot, high-UV regions than in temperate ones. That is why Middle East and Australian projects demand a more robust UV layer.
Local heat sources. Near luminaires, heaters and exhaust ducts, local temperature can far exceed ambient. Keeping distance or adding a heat shield works better than specifying thicker sheet.
Restrained expansion. Temperature change means movement; holes without clearance and both ends rigidly fixed will buckle or tear the panel. That is an installation problem, not an insufficient temperature rating.
Cold-climate greenhouses, where low-temperature toughness and multiwall insulation combine; tropical carports and canopies, where heat resistance and UV protection dominate; cold store doors and windows at -25 °C, replacing acrylic; and factory roof lights with large diurnal swings and local heat sources, where expansion allowance is critical.
"This sheet serves from -40 to over 100 °C — it works in a cold store and does not soften on a roof. But leave room for thermal expansion, or even a good panel will buckle."
Can it sit next to an oven or hot equipment? Not directly. Sustained exposure above the rated limit distorts the sheet and accelerates yellowing. Use a heat shield or maintain distance.
What about installing in cold weather? Below 5 °C the sheet hardens and cold bending cracks it. Install during warmer hours, pre-warm the panel, or increase the bend radius.
Is temperature resistance the same as flame retardancy? No. One is the service temperature range, the other is fire behaviour. They are assessed independently.
