PUF Roofing Panel Thickness Your Complete Guide to Choosing the Right Size for Every Project

PUF Roofing Panel Thickness plays a major role in how well a building holds up against heat, cold, rain, and noise. Choosing the right panel size is not just a technical decision — it directly affects how safe, efficient, and long-lasting your structure will be. Whether you are building a factory, warehouse, cold storage unit, or a simple shed, picking the correct thickness ensures your roof does its job properly for years to come.
Panels come in a range of sizes, typically starting from 40mm and going up to 200mm or more. Thinner panels work well for mild climates and light-duty applications. Thicker panels are better suited for areas with extreme temperatures or where strong insulation is needed. The foam core inside each panel is what gives it the power to block heat transfer, and a greater depth of foam means stronger thermal performance. This matters a lot for buildings where temperature control is critical.
When you mount a PUF Roofing system on top of a structure, the process needs careful planning. The panels must be aligned properly, fixed securely to the purlin framework, and sealed at every joint to prevent water from leaking through. A poorly mounted system can lead to heat loss, moisture damage, and structural problems over time. That is why choosing the right thickness before you mount the panels is so important thicker panels may require stronger support structures and more robust fasteners to hold them in place.
Beyond insulation, panel thickness also affects the load-bearing capacity of the roof. Thicker panels tend to be stiffer, which allows them to span longer distances between supports without sagging. This can reduce the number of purlins needed, saving both materials and labor costs during installation.
For industrial buildings in hot climates, a panel thickness of at least 60mm to 80mm is generally recommended. For cold storage or refrigeration facilities, thicknesses of 100mm to 150mm or even higher are commonly used to maintain the required internal temperatures efficiently. Always consult a structural engineer or roofing specialist to confirm the right choice for your specific needs.
Investing in the correct panel thickness upfront leads to lower energy bills, better indoor comfort, and a roof that lasts much longer with less maintenance required.
