Product overview
PU / PIR Sandwich Panels: overview and uses
PU (polyurethane) and PIR (polyisocyanurate) sandwich panels offer a higher insulation value per millimetre than EPS and improved fire performance in the case of PIR. They are preferred for air-conditioned warehouses, food and pharmaceutical facilities, clean rooms and any building where thermal control is a priority.
Available in roof and wall profiles. OGB confirms thickness, core type, colour and length per enquiry.
Build your panel
Choose core, thickness and colour
Pick a combination to see its insulation value, then send it to OGB as a quotation request. Every panel is made to order and cut to your length.
Colours shown are the common stock RAL shades; other RAL colours, PVDF coatings and different inner/outer colours are available on request. Screen colours are approximate, so confirm against a physical colour card.

Testing & standards
How PU/PIR Panels are tested
These are the test methods and standards that specifiers, civil defence and insurers ask about. Ratings belong to a specific tested system, so OGB supplies the certificate that matches your panel, thickness and joint.
- EN 14509
- European product standard for self-supporting double-skin metal-faced sandwich panels: dimensions, tolerances, strength, thermal and fire declarations.
- EN 13501-1
- Reaction-to-fire classification (A1, A2, B … F) of the panel or its core.
- EN 13501-2 / EN 1364
- Fire-resistance rating of a tested wall or roof system, written as EI 30, EI 60, EI 120 (integrity and insulation, in minutes).
- ASTM E84 / UL 723
- Surface burning characteristics: flame-spread and smoke-developed indices.
- FM 4880 / FM 4881
- FM Approvals tests for fire performance and for structural and wind-load performance of insulated panel systems.
- NFPA 285
- Large-scale fire-propagation test for exterior walls that contain combustible components.
- ASTM C518
- Laboratory measurement of thermal conductivity and R-value of the insulating core.
- ASTM E283 / E331
- Air leakage and water penetration through the panel joints under pressure.
Questions
PU / PIR Sandwich Panels: common questions
What R-value does a PU / PIR panel give?
With a core thermal conductivity of about 0.022 W/m·K, the core alone gives roughly R 2.3 m²·K/W at 50 mm, R 4.5 at 100 mm and R 6.8 at 150 mm (R = thickness ÷ λ). The manufacturer’s declared U-value for the full panel is used for design.
Are sandwich panels load-bearing?
No. Sandwich panels span between purlins or girts and carry wind, snow and maintenance loads across that span, but they are not a structural frame. The building still needs a steel or concrete frame, and panel spans are taken from the manufacturer’s load tables.
Why do roof panels cost more than wall panels?
A roof panel has a deep trapezoidal outer skin that uses more steel per square metre and needs a stiffer profile to shed water and carry foot traffic during installation, so the same core thickness costs more on a roof than on a wall.
When should the protective film be removed?
Remove the protective film from the panel faces during or soon after installation, and do not leave panels in direct UAE sun with the film on for long periods. Old, sun-baked film becomes hard to peel and can mark the paint.
Are panels kept in stock?
Panels are made to order: each project needs its own length, core, thickness and colour, so they are produced and cut for the order rather than held as stock lengths.
