The cold-storage sandwich panel market — dominated by polyurethane cores — is forecast to grow from USD 5.12B (2024) to USD 8.65B by 2033 at a 6.7% CAGR. Drivers include cold-chain expansion, food-safety regulation and energy-efficiency mandates. The polyurethane segment held ~68% market share in 2026.
The structural drivers behind a 6.7% CAGR through 2033 are familiar but worth restating: post-pandemic cold-chain build-out (food, pharma, retail e-grocery), tightening food-safety and HACCP enforcement in emerging markets, and the slow but persistent push from energy-efficiency codes (EPBD recasts in the EU, ASHRAE updates in the US, equivalent moves in MENA and SE Asia). Each of these favours higher-spec cold-room construction, which favours PU cores.
PU's ~68% share reflects the basic physics: closed-cell rigid polyurethane is among the highest-performing insulation cores per unit thickness, processable on continuous panel lines at meaningful throughput, and compatible with a wide range of skin systems. PIR variants extend the same chemistry into more demanding fire-rated specifications, and the share split between PUR and PIR within the panel segment is itself a strategic question for system suppliers.
