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 thickness choices from 50mm to 200mm and can be customized in length and surface steel finish to meet specific project requirements.

Q2: What thickness options are available for PIR panels?
We offer a range of thicknesses from 50mm to 200mm to meet different insulation requirements for various climates and applications.
Q3: Are the panels customizable in terms of color and material?
Yes, surface materials can be customized using PPGI (various colors), Stainless Steel, Embossed Aluminum, or specialized alloys like Ti-Mg-Zn-Al.
Q4: What is the fire rating of your PIR sandwich panels?
Our PIR panels typically achieve a fire resistance rating of B-s1, d0, providing excellent protection for industrial and commercial structures.
Q5: In which industries are PIR panels most commonly used?
They are widely used in cold storage, food processing plants, pharmaceutical warehouses, logistics centers, and modern industrial buildings.
Q6: How do these panels contribute to energy savings?
Due to their extremely low thermal conductivity (≤0.022 W/[m x K]), PIR panels provide superior insulation, which minimizes heat exchange and significantly reduces HVAC energy consumption.
