Construction Method and Its Effect on Consistency

Balance and load analysis shows that continuous-line lamination on a double-belt press delivers the tightest bond-line control for metal-faced PIR and mineral-wool cores. The facing coils — typically 0.5–0.7 mm pre-painted steel or 0.6–0.9 mm aluminum — enter the line under tension, the core is foamed or laid in situ, and the assembly cures under calibrated heat and pressure. Any drift in belt temperature uniformity exceeding ±3 °C across the 1,200 mm width creates measurable variation in core density and, consequently, in declared λ-value.

Discontinuous batch pressing, still common for shorter runs or special profiles, introduces a hard stop at each cycle. That stop shows up as a 0.2–0.4 mm step in panel thickness at the joint line, which later telegraphs through the façade as a shadow line under raking light. For OEM programmes where panels from three different production weeks must sit flush on the same elevation, continuous-line origin is the only practical guarantee.

Customisation Options and Their Limits

The interface between parts determines whether a custom colour or texture survives the first winter. Metallic and pearlescent PVDF coats demand a minimum 35 µm DFT; anything thinner shows differential chalking at cut edges within 18 months. Textured PVC plastisol (Leather-grain, Stucco) masks minor handling damage but adds 0.15 kg/m² dead load — relevant on retrofit over lightweight steel frame where every kilogram counts against the original structural design.

Who Uses It and Where It Matters

Retail park developers and modular housing fabricators form the third tier. They order 60–100 mm panels in standard widths, but their warranty exposure comes from colour batch drift across multiple delivery dates. A single RAL 9016 coil lot covers 8,000 m²; splitting an order across two coil lots without a master-batch agreement guarantees a visible seam at the building corner.

Inspection Items and Test Methods

Deflection under load governs the structural sign-off for spans beyond 4.5 m. Every production shift runs a three-point bend test on a 3 m coupon cut from the first, middle, and last panel of the run. Load at 15 mm deflection is recorded; the batch passes only if the coefficient of variation across the three coupons stays below 6 %.

Capacity, Tooling and Scheduling

Two continuous lines operate on a 24/5 pattern: Line A (1,200 mm width, max 16 m length) dedicated to PIR/PUR; Line B (1,250 mm width, max 18 m) for mineral wool. Combined theoretical output is 1.2 million m²/year, but realistic throughput after coil changes, profile swaps, and planned maintenance settles at 850 k m². A standard RAL colour on stocked coil gauge ships in 10 working days from order confirmation. Custom coil colour adds 15 days for paint-line scheduling; custom roll-form die adds 6 weeks tooling plus 1 week trial run.

Tooling amortisation is baked into the unit price above 15,000 m² per custom die. Below that threshold, the die cost appears as a separate NRE line item. We hold dies for 36 months after last order; after that they are scrapped unless a renewal PO is in hand.

Questions Buyers Ask Before Ordering

1. Can we run a 500 m² trial in our exact spec before committing to the full 20 k m² programme? Yes — minimum trial is one coil (≈ 2,500 m²) on Line A or B. We invoice at standard rate plus a €1,200 line-setup fee, credited against the follow-on order if placed within 60 days.
2. How do you guarantee colour consistency across three delivery dates spaced six weeks apart? We allocate a single master coil lot for the full project quantity. If the lot is insufficient, we split only with a spectrophotometer-verified master-batch agreement (ΔE ≤ 0.8) signed by your QC and our coating supplier.
3. What is the real-world R-value of a 120 mm PIR panel after five years in a North European climate? Declared λ 0.022 W/m·K ages to ≈ 0.026 W/m·K (blowing-gas diffusion). That yields R 4.6 m²·K/W vs. initial R 5.4. Design to the aged value; the 15 % drop is already in EN 14509 Annex C.
4. Do you supply the concealed clip system or just the panel? We supply clips (stainless A2, 1.5 mm) packed with panels at 600 mm centres. Clip design is validated per project wind-load calc; we do not sell clips standalone.
5. How are cut-edge corrosion warranties handled on micro-rib profiles? Factory-applied edge coat (epoxy primer + 25 µm topcoat) on all cut edges is standard for coastal projects (C4/C5). Warranty matches the facing coat — 15 years for PVDF, 10 years for polyester — provided installer does not grind or weld within 50 mm of the panel edge.
6. What documentation ships with each batch for CE/UKCA compliance? Declaration of Performance (DoP) per EN 14509, factory production control certificate, coil mill certificates for steel/Al, core batch test report, and a packing list with panel IDs traceable to the shift log.
