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.

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. PPGI is also very environmentally friendly as its production process produces less waste. PPGI has a long service life and minimal maintenance requirements, making it ideal for roofing, wall cladding and other applications.

Extra Coating
PPGI can also be enhanced with various advanced coatings to improve its performance and durability.
Typical coating includes:
1. PVDF (Polyvinylidene Fluoride): Known for its exceptional resistance to UV radiation, chemicals, and weathering, PVDF provides a glossy finish that retains color vibrancy over time. This makes it ideal for outdoor applications, particularly in architectural projects.
2. HDP (High-Durability Polyester): HDP coatings offer superior durability and scratch resistance, making them suitable for high-traffic areas and industrial environments. They protect against corrosion and environmental factors, extending the lifespan of the material.
3. EP (Epoxy Polyester): This coating combines the benefits of epoxy and polyester, providing excellent adhesion and resistance to chemicals and moisture. EP coatings are ideal for indoor applications and environments where chemical exposure is a concern.
These advanced coatings significantly enhance the functionality and longevity of surface, making it a preferred choice for various applications in construction and manufacturing.
PIR sandwich panels combine excellent thermal insulation, cost-effectiveness, safety, and versatility, making them the first choice for modern construction needs. Their core competitive advantage is the ability to deliver long-term energy savings while ensuring structural integrity and safety.

Frequently Asked Questions (FAQ)
QWhat is a PIR sandwich panel and how does it differ from PUR?
PIR (Polyisocyanurate) sandwich panels use a foam core that is a polyurethane-modified form of polyisocyanurate. Compared to PUR (Polyurethane) sandwich panels, PIR offers lower thermal conductivity and significantly better fire resistance, making it a superior choice for applications where both insulation performance and fire safety are critical.
QWhat thickness options are available for PIR sandwich panels?
Our PIR sandwich panels are available in standard thicknesses ranging from 50mm to 200mm (50, 75, 100, 120, 125, 150, and 200mm). Panel length and surface steel finish can also be fully customized to meet specific project requirements.
QWhat surface materials and finishes can be chosen for PIR panels?
PIR sandwich panels can be supplied with a wide range of surface materials including PPGI (Prepainted Galvanized Iron), Stainless Steel (SUS304/SUS201), Embossed Aluminum, and various alloys such as Ti-Mg-Zn-Al. Multiple color options and advanced coatings (PVDF, HDP, EP) are also available for enhanced performance and aesthetics.
QWhat are the typical applications for PIR sandwich panels?
PIR sandwich panels are widely used in cold storage facilities, industrial buildings, food markets, hotels, logistics centers, food industry facilities, agricultural warehouses, and medicine storage. Their excellent thermal performance and fire resistance make them suitable for any application where energy efficiency and safety are priorities.
QWhat is the fire resistance rating of PIR sandwich panels?
Our PIR sandwich panels achieve a fire resistance classification of B-s1, d0, which indicates limited combustibility, minimal smoke production, and no flaming droplets. This rating makes them a safe and reliable choice for commercial and industrial construction projects.
QAre PIR sandwich panels environmentally friendly and suitable for green building projects?
Yes. PIR sandwich panels contribute to green building certification due to their excellent thermal insulation properties, which significantly reduce energy consumption for heating and cooling. Their lightweight nature reduces transportation emissions, and the use of PPGI surface material — which produces minimal waste during manufacturing — further supports sustainable construction goals.
