Structured courses at three levels — from panel foundations to factory investment engineering.






Six categories — technical, production, investment, engineering, installation and maintenance.
For −25 °C, a 150–180 mm PIR panel typically reaches U ≈ 0.14 W/m²K, meeting energy targets in most climates. Use our Panel Thickness Calculator to size for local conditions.
PUR is a polyurethane rigid foam; PIR is polyisocyanurate — a modified PUR with higher aromatic content that improves fire performance (typically B-s1,d0) while retaining a low λ ≈ 0.022 W/mK.
U = λ / d, where λ is thermal conductivity (W/mK) and d is core thickness in metres. Skins and interfaces add small resistances; EN 14509 gives the full method.
Continuous PIR lines run 6–15 m/min depending on thickness and panel type. Rock wool lines are slower — typically 3–8 m/min due to lamella insertion.
A fully automated NEVO line runs with 6–8 operators per shift, plus quality, maintenance and warehouse staff.
World-class continuous lines reach 82–88% OEE. New factories typically start at 60–70% and improve over 12–18 months with SPC and TPM programmes.
A 1 M m²/yr continuous PIR factory typically costs 8–12 M USD turnkey (line + building + utilities + working capital), depending on automation level and country.
Typical payback is 3.5–5 years at 35–45% gross margin. Our Investment Calculator models CAPEX, OPEX, IRR and NPV for your inputs.
Yes — plan a second line at Year 3 with ~55% incremental capex. Design the building and utilities for Phase II from day one.
Most markets recognise EN 13501-1 (EU) or ASTM E84 (US). Petrochemical projects add EI-integrity per EN 1364-1. Ask our engineers for a country-specific reference.
Roof panels use 5-rib trapezoidal profiles for drainage and load-span; wall panels use micro-rib or flush profiles for aesthetics. Both use the same core technology.
Wall panels use hidden or exposed fasteners into steel purlins/rails per panel manufacturer detail. Cold room panels use cam-lock joints for tight thermal seal.
Continuous lines produce panels up to 24 m for standard trucks. Special transport (flat-rack containers, break-bulk) enables longer panels for architectural projects.
Annual visual inspection is standard; a full fastener and seal check every 3 years. Coastal environments require 6-month inspections and touch-up of any coating damage.
Well-maintained PVDF-coated panels have a service life of 30–40 years; polyester-coated panels 15–25 years. Cores retain thermal performance for the panel's full life.
