Rigid Polyurethane Panels are closed-cell foam insulation boards or sandwich panels engineered for superior thermal resistance, low water absorption, and high compressive strength. At NNRV, we supply PU and PIR panels in multiple configurations tailored to suit cold-chain logistics, commercial buildings, and energy-efficient construction.
From roof and wall panels for steel buildings to high-density PIR core panels for refrigeration and pharma, NNRV offers fire-rated, CE-marked solutions for fast installation, long life, and optimal thermal performance.

❓ Frequently Asked Questions (FAQs)
Q1: What’s the difference between PU and PIR panels?
PIR has higher fire resistance and slightly better thermal stability than PUR.
Q2: Can you supply ready-cut panels for cold rooms?
Yes – we can pre-cut, label, and package panels with cam-lock joints and insulation tape.
Q3: Do you offer antibacterial or food-grade facing?
Yes – stainless steel or PET laminated facings available for food/pharma projects.
Q4: What joint systems are available?
Cam-lock, concealed screw, tongue-and-groove, and clip-lock joints.
Q5: Minimum order quantity?
1×20 ft container (~250–350 m² depending on panel thickness and spec).
