Products Description
Polyisocyanurate (PIR) sandwich panels are at the forefront of modern insulation technology, delivering unparalleled thermal performance and energy efficiency. As an efficient performance, easy installation, high quality and environment friendly material, PIR Sandwich Panel is now widely used in cold storage, industrial buildings, food markets, hotels, logistic centers, food industry facilities, agricultural and medicine warehouses, etc.
Product Details
PIR (Polyisocyanurate Foam) is polyurethane modified polyisocyanurate. It is a foam plastic obtained by polyurethane modification of a kind of foam called polyisocyanurate. Its performance is quite different from polyurethane. Compared with PUR sandwich panels, PIR has lower thermal conductivity and better fire resistance.
Our PIR Sandwich panel has the thickness choice from 50mm to 200mm, and can be customized in length and surface steel finish to meet specific project requirements.

QWhat is a PIR sandwich panel and how does it differ from PUR?
PIR (Polyisocyanurate) sandwich panels use a modified foam core that offers lower thermal conductivity and significantly better fire resistance compared to standard PUR (Polyurethane) panels.
QWhat thickness options are available for PIR panels?
Standard thicknesses range from 50mm to 200mm (50, 75, 100, 120, 125, 150, and 200mm). Lengths and finishes can be fully customized for your project.
QWhat surface materials can I choose from?
Options include PPGI (Prepainted Galvanized Iron), Stainless Steel (SUS304/SUS201), Embossed Aluminum, and specialized alloys like Ti-Mg-Zn-Al with various high-performance coatings.
QWhere are these panels typically used?
They are ideal for cold storage, industrial plants, food processing facilities, logistics centers, medicine warehouses, and any building requiring high thermal efficiency.
QWhat is the fire resistance rating?
Our PIR panels achieve a B-s1, d0 classification, meaning they have limited combustibility, produce minimal smoke, and result in no flaming droplets during fire exposure.
