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.

The Joint
The Split Joint PIR sandwich panels are widely used in industrial, commercial, and agricultural buildings, including warehouses, cold storage facilities and manufacturing plants. Their ease of installation and low maintenance requirements make them a cost-effective option for modern construction projects, helping to increase sustainability and efficiency.
Surface Material
Our PIR sandwich panel have multiple customizable surface steel material and color choices such as PPGI, Stainless steel, embossed aluminum etc. Their durability, moisture resistance and chemical resistance further enhance their appeal.
PPGI
PPGI, or Preprinted Galvanized Iron, is a versatile metal material widely used in construction and manufacturing. It features a galvanized steel base that is coated with a layer of paint for excellent corrosion resistance and durability. Key features include its lightweight nature and its availability in a variety of colors and finishes for aesthetic customization.

Extra Coating Options
PPGI can also be enhanced with various advanced coatings to improve its performance and durability.
1PVDF (Polyvinylidene Fluoride): Known for exceptional resistance to UV radiation and chemicals, retaining color vibrancy over time.
2HDP (High-Durability Polyester): Offers superior durability and scratch resistance, suitable for high-traffic industrial environments.
3EP (Epoxy Polyester): Provides excellent adhesion and resistance to chemicals and moisture, ideal for indoor applications.
Frequently Asked Questions
QWhat is the difference between PIR and PUR sandwich panels?
PIR (Polyisocyanurate) is a polyurethane-modified foam that offers lower thermal conductivity and better fire resistance compared to PUR (Polyurethane) sandwich panels. This makes PIR panels superior for high-performance thermal insulation and fire safety.
QWhat thickness options are available for PIR sandwich panels?
Standard thicknesses include 50mm, 75mm, 100mm, 120mm, 125mm, 150mm, and 200mm. Custom thicknesses and lengths (1-18m) can be arranged to meet specific project requirements.
QWhat surface material options are available?
Panels can be customized with PPGI (Prepainted Galvanized Iron), Stainless Steel (SUS304/SUS201), Embossed Aluminum, and other alloys. Advanced coatings like PVDF, HDP, and EP are also available for enhanced durability.
QWhat is the fire resistance rating?
Our PIR sandwich panels achieve a fire resistance classification of B-s1, d0. This indicates limited combustibility, minimal smoke production, and no burning droplets, making them safe for industrial and commercial use.
QWhat are the typical applications?
They are widely used in cold storage, industrial buildings, food processing plants, logistics centers, hotels, agricultural warehouses, and medicine storage facilities.
QCan these panels be customized?
Yes, PIR panels offer extensive customization in thickness (50mm–200mm), length (1–18m), surface profiles (Miro, Smooth, Linear, Embossed), and various material finishes and color options.
