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 the cold storage, Industrial buildings, food markets, hotels, logistic centers, food industry facilities, agricultural and medicine warehouse 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.

Frequently Asked Questions
Q What is a PIR sandwich panel and how does it differ from PUR?
PIR (Polyisocyanurate) is a modified polyurethane foam. Compared to PUR, PIR offers significantly lower thermal conductivity and superior fire resistance, making it safer and more energy-efficient for industrial applications.
Q What thickness options are available?
We offer a standard range from 50mm to 200mm (including 75mm, 100mm, 120mm, 125mm, and 150mm). Lengths and surface finishes can be customized based on specific project needs.
Q What are the primary applications for these panels?
They are ideal for cold storage, logistics centers, food processing facilities, pharmaceutical warehouses, and any commercial or industrial building requiring high thermal regulation.
Q What is the fire resistance rating?
Our PIR panels achieve a B-s1, d0 classification. This means they have limited combustibility, produce minimal smoke, and result in no flaming droplets during a fire.
Q Can these panels be used for green building projects?
Yes. Due to their exceptional insulation properties and the use of recyclable surface materials like PPGI, PIR panels significantly reduce a building's carbon footprint and support sustainability certifications.
