PIR / PUR sandwich panels — Jiangsu & Henan factory-direct to Irish industrial contractors
PIR (polyisocyanurate), PUR (polyurethane), and mineral-wool insulated sandwich panels are the standard envelope solution for cold-storage facilities, industrial sheds, agricultural buildings, modular construction, and warehouse-distribution centres. Ériu Sourcing accesses two distinct inland-China sandwich-panel clusters direct: the Jiangsu cluster for premium-spec PIR and mineral-wool systems comparable to European panel manufacturers, and the Henan cluster for value-tier panel systems where the Jiangsu premium isn't required. The dual-cluster framing means each brief gets matched to the right factory by spec, budget, and project timeline.

Jiangsu Province (premium-spec PIR cluster) · Henan Province (value-tier panel cluster)
The Jiangsu sandwich-panel cluster comprises approximately 117 major manufacturers — among the largest concentrations in China — supplying premium-spec PIR and mineral-wool panel systems to European industrial-building markets. The Henan cluster comprises approximately 20 manufacturers — smaller than Jiangsu but with strong dispatch logistics out of Zhengzhou and competitive value-tier pricing for less-demanding building envelope applications. Together the dual-cluster source covers the full European-market specification range from premium cold-storage to value-tier industrial shed.

Technical specification
| PIR core panels | Thicknesses 30, 40, 50, 60, 80, 100, 120, 150, 200 mm; densities 40–60 kg/m³ |
|---|---|
| PUR core panels | Similar thickness range; lower fire-classification than PIR (less common in EU spec) |
| Mineral-wool core panels | Thicknesses 50–200 mm; Class A2-s1,d0 fire-rated; for higher fire-spec buildings |
| Steel skin | Cold-rolled galvanised steel 0.4 / 0.5 / 0.6 mm; PE / PVDF coating; standard RAL colours |
| Panel profiles | Standard mini-rib, micro-rib, flat, deep-rib; standard widths 1000 / 1150 mm; custom lengths to 13.5 m |
| MOQ | Single 40HQ container (~280–400 m² depending on thickness); mixed-spec orders accepted |
What we verify at the factory — before the container is sealed
- EN 14509 — Self-supporting double skin metal-faced insulating panels
- EN 13501-1 — Reaction to fire (PIR typically B-s2,d0; mineral-wool A2-s1,d0)
- CE marking + EU Declaration of Performance per CPR (EU) 305/2011
- EN 1993-1-1 — Steel structures (panel skin thickness validation)
- EN ISO 12944 — Corrosion protection (steel-skin coating spec)
- Thermal-conductivity declared value (λ-value) on EU Declaration
Goods that fail compliance or pre-shipment QC stay in China at the factory's cost — you do not pay freight on non-compliant product.

A standard 100 mm PIR insulated sandwich panel with 0.5 mm galvanised steel skin and PE coating in standard RAL colour ships factory-direct from the Jiangsu premium cluster at €18 to €24 per m² FOB factory, landing in Ireland at approximately €26 to €34 per m² after freight, duty, VAT and customs. The Henan value-tier cluster typically lands 15–20% lower again. Irish builders'-merchant trade pricing for equivalent specification typically runs €58 to €78 per m² — a landed-cost saving of 45–55% from the Jiangsu cluster, 55–65% from the Henan cluster.
Lead time and logistics
Lead time: 4–7 weeks production + 4–5 weeks sea freight (Shanghai or Ningbo → Dublin).
Sandwich panels ship in 40HQ containers — typical load 280–400 m² per container depending on panel thickness, banded on heat-treated wooden pallets with edge protection. Standard panel lengths up to 13.5 m fit in standard 40HQ — longer custom-length panels may require open-top or flat-rack shipment. Ériu coordinates Dublin Port or UK port reception and inland delivery to the contractor's yard or directly to project site.
Construction Materials — sourcing questions answered
When should I specify Jiangsu cluster vs Henan cluster sandwich panels?
Jiangsu cluster premium-spec is the right choice for cold-storage facilities (where PIR panel performance and steel-skin integrity matter most), pharmaceutical and food-grade buildings, and projects with demanding fire-classification requirements. Henan cluster value-tier is the right choice for general industrial sheds, warehouse-distribution buildings, agricultural buildings, and modular-construction envelope where the Jiangsu premium specification isn't required and budget pressure is strong. Ériu evaluates each brief and recommends the right cluster.
How does inland-China sandwich panel performance compare to Kingspan or Tata Steel?
The premium-spec Jiangsu cluster produces PIR and mineral-wool sandwich panels comparable to Kingspan Kooltherm and Tata Steel ComFlor in thermal performance, fire classification, panel-joint integrity, and steel-skin durability. The Henan value-tier cluster sits below the Jiangsu specification level — adequate for general industrial-building envelope but not directly equivalent to Kingspan premium products. Ériu verifies the EN 14509 test reports and EU Declaration of Performance at the factory.
What is the typical landed-cost saving versus Kingspan or Irish trade pricing?
Jiangsu cluster typically lands at 45–55% below Irish trade-merchant pricing for equivalent Kingspan PIR or mineral-wool specification. Henan cluster typically lands at 55–65% below for value-tier applications. The saving is largest on thick (>120 mm) PIR systems for cold-storage where the Kingspan premium is highest, and smallest on basic 50 mm panels for general industrial-shed envelope.
Are inland-China sandwich panels fire-compliant for Irish industrial-building Part B?
Yes. Premium-spec Jiangsu cluster supplies EN 14509 + EN 13501-1 Class B-s2,d0 (PIR core) and Class A2-s1,d0 (mineral-wool core) panels for Irish Building Regs Part B compliance. PIR panels are appropriate for general industrial buildings; mineral-wool panels are typically specified for buildings above 18 m height or where higher fire-classification is required. Ériu verifies the fire-classification test report at the factory and supplies it with the order pack.
Can the cluster supply matching flashings, trims, and fixings?
Yes — matching ridge flashings, eaves flashings, corner trims, valley gutters, and panel-fixing screws all ship from the same Jiangsu or Henan cluster in matching colour and finish to the main panel order. Steel fixings source from the adjacent Yongnian (Hebei) fastener cluster — Ériu consolidates the full project bill-of-materials into a single shipment where possible.
