PU / PIR Sandwich Panels — Wholesale Manufacturer

Insulated metal panels for walls, roofs and cold rooms. Continuous-line PU and PIR foam cores bonded to PPGI steel skins — the same insulation technology inside our garage door panels, in building-scale sheets.

Why PU / PIR Cores

• Best insulation per inch among foam cores — thinner walls, same thermal performance
• Closed-cell structure resists moisture, so panels keep their R-value over time
• PIR cores add improved fire performance for code-sensitive projects
• Lightweight sheets install fast — fewer lifts, lower labor cost on site
• Your brand and color program available (OEM)

Applications

Industrial and commercial wall cladding, warehouse and factory roofing, cold rooms and refrigerated warehouses (cam-lock panels on request), prefab and modular buildings. Ask for panel layout drawings with your quote.
