When to use this system
The insPIRe® S panel is the market standard for industrial hall walls — offering the best price-to-performance ratio:
- Halls and warehouses — the default choice when there are no special aesthetic requirements (e.g. hidden U fastening).
- Big-box retail facilities — quick installation of large modules (up to 16 m in length).
- Hangars, agricultural buildings — where price and simple installation matter most.
- Automotive and repair workshops — easy servicing (individual panels can be replaced).
Characteristics of the S joint
The S system features a joint with a visible external fastener — the screw is driven through the protruding part of the panel joint. This is the difference compared to the U variant (hidden fastener):
| Aspect | S (visible fastening) | U (hidden fastening) |
|---|---|---|
| Cost per m² | lower | 15–20% higher |
| Façade aesthetics | visible fastener heads | smooth, linear appearance |
| Installation speed | faster | slightly slower (precise seating) |
| Typical application | halls, warehouses | offices within halls, representative buildings |
insPIRe® S variants
- insPIRe® S — standard, PIR core, λ 0.022 W/(m·K), thicknesses 40–120 mm.
- insPIRe® S MAX — PIR-MAX core, λ reduced to 0.019 W/(m·K). Allows U = 0.16 W/m²·K at 120 mm (vs 0.19 in the standard variant).
Geometry
- Modular width: 1000 or 1140 mm (depending on thickness and profiling).
- Length: 2.0–16.0 m.
- External profiling: L (linear), M (micro-profiled), F (wave), R (grooved), P (smooth) — aesthetic choice.
- Internal profiling: L (linear) or P (smooth).
- Colours: standard palette RAL 7016, 7035, 9002, 9006, 9007, 9010 + other RAL on request.
Required flashings
The wall system uses a full set of flashings:
- OB-01 / OB-02 — external / internal corner
- OB-17 — masking the panel joint
- OB-22 — ridge flashing (at the wall-to-roof junction)
- OB-36 — panel closure
- OB-37 — window sill
Technical documentation
The system is described in the Gór-Stal 2025 Technical Catalogue. NRO + B-s1,d0 classification, fire resistance EI 15–EI 30, PZH hygiene certificate. CE according to EN 14509:2013.
Layer composition
| # | Layer | Thickness | λ | Role |
|---|---|---|---|---|
| 1 | External facing — galvanised steel sheet S220-S280GD + 25 µm coating (L/M/F/R/P profiles) | 0.5–0.7 mm | — | external facing |
| 2 | PIR / PIR-MAX core (density 40 kg/m³ ±10%) | 40–120 mm | 0,022 W/(m·K) | main insulation |
| 3 | Internal facing — steel sheet + 25 µm coating (L/P profile) | 0.4–0.5 mm | — | internal facing |
U-value by insulation thickness
| termPIR® thickness | U [W/m²·K] | Meets WT 2021 (roof U ≤ 0.15) |
|---|---|---|
| 40 mm | 0,60 | — no |
| 60 mm | 0,38 | — no |
| 80 mm | 0,28 | — no |
| 100 mm | 0,22 | — no |
| 120 mm | 0,19 | — no |
