Quick answer

What is a PUF sandwich panel?

A PUF sandwich panel is a rigid polyurethane foam core, typically 38–42 kg/m³, bonded between two coated steel skins. Continuous panels (30–150 mm) clad walls and roofs of warehouses and sheds; cam-lock panels (60–200 mm) lock together into cold rooms and freezers. PIR cores add better fire behaviour.

Core materials

PUF, PIR, EPS or rockwool?

The core decides the insulation, the fire behaviour and the weight. All values are typical and vary by brand.

Corek (W/mK)Density (kg/m³)FireBest for
PUF≈0.02238–42Combustible (FR grades exist)Best insulation per mm; standard for cold rooms
PIR≈0.02240–45Better fire behaviour; charsInsurer-friendly; slightly higher cost
EPS≈0.035–0.03815–20CombustibleCheapest; ambient-temperature cabins
Rockwool≈0.040–0.04580–120Non-combustible coreFire walls; heavy; absorbs water if damaged
