If you’re exploring 75mm sandwich panel price for your next warehouse, cold room, or prefab office project, this guide brings you verified information based on 2024–2025 factory audits, CNAS testing, and research from Elsevier and RIBA Publishing. You’ll learn real market prices, performance data, and how to choose the right panel for your application.
What Is a 75 mm Sandwich Panel — and Why It Matters
Recent studies (Elsevier, 2024) confirm that panels between 70 and 80 mm offer up to 32 % better thermal resistance than 50 mm units — without the extra weight or cost of 100 mm systems. That’s why 75 mm has become the new engineering standard for energy-efficient warehouses, modular offices, and prefab housing worldwide.
In short: 75 mm panels balance thermal performance, fire safety, and structural strength, making them the preferred thickness for most industrial buildings.

How to Select the Right Panel
Define the environment: Cold room → PIR or PU. Fire zone → Rock Wool. Office → EPS.
Consider the climate: Tropical regions benefit from PIR cores.
Check fire codes: If A1 or FM approval is required, choose Rock Wool or FM-certified PIR.
Request a layout plan: Factory layout drawings are available for projects over 500 m².
Frequently Asked Questions
How much does a 75 mm sandwich panel cost in 2025?
Typically between $10 and $45 per m², depending on core type and region.
Which core offers the best thermal performance?
PIR — highest R-value (~4.2 m²·K/W) and B1 fire rating.
Are these panels fire-certified?
Yes. Rock Wool (A1) and FM-approved PIR meet EN and ASTM standards.
Do you ship worldwide?
Yes. FOB China or CIF Singapore, UAE, Philippines, and Africa are available.
