Is This Panel Suitable for Your Project?

Project requirement	Decision guidance
Steel structure factory / workshop	Suitable application; Confirm roof design and load requirements.
Logistics warehouse	Suitable application; Select thickness according to insulation requirement.
Factory extension	Suitable for lightweight enclosure/roofing applications; Confirm interface details.
Hot and high-UV environment	Select an appropriate coating system and verify weathering requirements.
Strong wind / dusty environment	Use project-specific fasteners, sealing and flashing; wind-load verification required.
Specific fire-rating requirement	Select only a panel system supported by the required test report/classification.
Cold storage / high thermal requirement	Compare required thermal performance with thicker EPS or alternative core systems before selection.

How to Choose the Right Panel Thickness

Select panel thickness based on local climate, insulation requirements and purlin span. Thicker panels deliver better thermal resistance. Roof load, maximum span and project specifications must be validated prior to final selection. All data is for preliminary reference only.

Thickness	50 mm	75 mm	100 mm	120–150 mm
Typical decision direction	General/light insulation requirements	Higher insulation requirement than 50 mm	Higher thermal insulation demand	Projects requiring greater insulation thickness
Information still required	Project thermal target and climate	Required U-value/R-value	Thermal calculation and project use	Thermal calculation, structure and budget
Typical U-value	0.72 W/(m²·K)	0.48 W/(m²·K)	0.36 W/(m²·K)	0.30 / 0.24 W/(m²·K)
Typical R-value	1.39 m²·K/W	2.08 m²·K/W	2.78 m²·K/W	3.33 / 4.17 m²·K/W
Water Absorption (Core)	≤4% (vol.)	≤4% (vol.)	≤4% (vol.)	≤4% (vol.)
Compressive Strength (EPS Core)	≥120 kPa	≥120 kPa	≥120 kPa	≥120 kPa
Roof Load Capacity	Light roof load; depends on steel gauge & support spacing	Medium roof load; check purlin spacing	Medium-heavy roof load	Heavy roof load, longer span design
Maximum Span	Max span ~2.0–2.4m;	Max span ~2.4–2.8m;	Max span ~2.8–3.2m;	Max span ~3.2–3.8m;
