PIR sandwich panels — insPIRe®
PIR sandwich panels with steel facings. 8 variants for halls, warehouses and cold stores. Sandwich panels from Poland — EU delivery.
insPIRe® is the Polish market leader in PIR sandwich panels, made by Gór-Stal. Sandwich construction: two steel facings + PIR core + GS-Lock joint with factory-applied PUS gasket. 8 variants selected by partition type and thermal requirements:
- S / S MAX — wall panels, standard fixing (exposed), for hall and warehouse facades
- U / U MAX — wall panels, concealed fixing (cleaner linear architectural appearance)
- CH / CH MAX — cold storage panels for freezers and cold stores (joint with additional PUS gasket)
- D / D MAX — trapezoidal roof panels for industrial halls
Common parameters: PIR core, λD = 0.022 W/(m·K) in standard variants; in the MAX series lambda drops to 0.019 W/(m·K) (S MAX, U MAX, CH MAX) or 0.020 W/(m·K) (D MAX). Fire reaction class B-s1,d0 for all variants, module length up to 16.5 m, core thicknesses 40–200 mm.
When MAX vs standard: MAX has a better lambda (10–15% thinner wall for the same insulation performance) — important under the new WT2021 regulations and where facade thickness is constrained.

Frequently asked questions
What is a PIR sandwich panel and how does it differ from an insulation board?+
An insPIRe® sandwich panel is a ready structural cladding element: two steel facings + a PIR core + the GS-Lock joint with a factory-applied gasket. It is installed directly as a hall wall or roof — without any additional cladding framework. That sets it apart from an insulation board (termPIR®), which is the insulation itself placed inside the building envelope and does not perform a load-bearing or cladding function.
What buildings are insPIRe® sandwich panels used for?+
Mainly industrial halls, warehouses, production facilities, cold stores and farm/utility buildings. The line has 8 variants: wall (S/U), roof (D), cold-store, and a MAX series with lower lambda. The variant is chosen for the partition type (wall/roof), thermal requirements and façade aesthetics.
What is the reaction-to-fire class of insPIRe® panels (PIR core)?+
PIR sandwich panels with steel facings reach a system class of B-s1,d0 / B-s2,d0 per EN 13501-1 (depending on the variant). If the project requires a non-combustible (A2) material — e.g. fire-separation walls — mineral-wool-core panels [GS MW](/en/products/plyty-warstwowe-miwo/) are used instead.
What is the difference between the standard (S) and hidden (U) joint?+
In panels with a standard joint (S) the fixing is visible on the face — an economical solution, typical for hall and warehouse façades. In panels with a hidden joint (U) the fasteners are concealed in the joint — a cleaner, linear architectural look. S and U variants should not be mixed within one partition (different fixing system).
What is the lead time for sandwich panels and how are they transported?+
Sandwich panels are made to order (to a specific size and colour), with a typical lead time of about 35 working days. The transport method is matched to the size and dimensions of the order — full-length panels (up to several metres) require truck transport, smaller orders can travel on a pallet. Nationwide delivery, directly to the site; unloading on the recipient's side.
Do you help select accessories for sandwich panels?+
Yes — we offer a complete system: sandwich-panel fasteners, flashings, tapes and gaskets, self-drilling screws. A technical advisor will prepare an accessory list matched to the project (substructure type, panel thickness, wind zone).
