Sandwich Roof Panel with PIR / PUR Foam Core
products description
Our PIR or PUR Sandwich Roof Panel with the features of high thermal insulation value, lightweight, moisture resistant, durability, energy efficiency, versatility and easy installation, sandwich roof panel become a popular solution. PIR or PUR Sandwich roof panels are used in a wide variety of applications including industrial buildings, commercial buildings, agricultural structures as well as cold storage facilities.
Product Details
Our PIR/PUR roof panels adopt a three-wave crest design with a crest height of 36mm, which greatly improves the roof drainage effect and load-bearing capacity. It can effectively reduce construction costs while ensuring the thermal insulation effect of the building. The roof slope can be low as 3%. With exposed nail design, the nail fixing space is adjustable from 250mm to 1000mm.

The Joint
The exposed nail design with split joint of our sandwich roof 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/PUR Sandwich Roof 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.

-Other Surface Material
To Obtain better or specific function, other surface materials can also be customized.
Such as Stainless Steel ( SUS304 / SUS201), Aluminum, or other alloy ( Zinc, Magnesium, Titanium, etc.).
Ti-Mg-Zn-Al Alloy
Embossed Aluminum
Stainless Steel (SUS304)
-Extra Coating
PPGI can also 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.
More About PIR/PUR Sandwich Roof Panel
1. High thermal insulation value: PUR foam has one of the lowest thermal conductivity among thermal insulation materials, usually about 0.022-0.025 W/m·K. This high insulation value minimizes heat transfer and ensures the building’s energy efficiency.
2. Lightweight: Although PUR panels have strong insulating properties, they are lightweight, which simplifies handling and installation. This feature reduces the overall structural load on the building, making it suitable for a variety of applications.
3. Moisture Resistant: The closed-cell structure of polyurethane foam prevents moisture absorption, which is critical to maintaining the integrity of your roof and preventing problems like mold and mildew.
4. Durability: PUR boards are resistant to a variety of environmental factors, including chemicals, UV radiation, and physical impact. This durability ensures a long service life, reducing the need for frequent maintenance or replacement.
PUR (Polyurethane) / PIR (Polyisocyanurate) sandwich roofing panels are an excellent choice for modern construction due to their high heat resistance, lightness, moisture resistance and durability. Its unique construction enables efficient temperature control, making it essential in a variety of applications from industrial and commercial buildings to agricultural buildings and cold storage facilities. As industries continue to prioritize energy efficiency and sustainability, demand for PUR panels is likely to grow, cementing its role as the cornerstone of contemporary roofing solutions. By investing in PUR sandwich roof panels, businesses can ensure the integrity of their buildings while optimizing operating costs and minimizing environmental impact.
