Applications
PU panels are known for their excellent cost-effectiveness and thermal insulation performance, making them the preferred choice for most small and cost-sensitive cold storage projects.
Fruit & Vegetable Cold Storage
Fresh produce requires stable temperatures rather than high fire ratings, making PU panels an economical solution.
Meat Cold Storage
For standard meat cold storage projects, PU panels provide the ideal balance between energy efficiency, durability, and investment value.
Seafood Cold Storage
Since most seafood cold rooms prioritize thermal efficiency over enhanced fire performance, PU panels offer a more cost-effective solution than PIR.
Dairy Cold Storage
PU panels offer the performance required for preserving milk, cheese, yogurt, and other dairy products at a more economical price.
