Product Description
Our PIR or PUR Sandwich Roof Panel features high thermal insulation values, lightweight construction, moisture resistance, durability, energy efficiency, and versatility. These characteristics make it a popular solution for modern architecture. PIR or PUR Sandwich roof panels are extensively used across various applications including industrial buildings, commercial complexes, agricultural structures, and specialized cold storage facilities.
Product Details
Our PIR/PUR roof panels adopt an advanced three-wave crest design with a crest height of 36mm. This significantly improves roof drainage efficiency and load-bearing capacity. It effectively reduces construction costs while maintaining superior thermal insulation. The roof slope can be as low as 3%. Featuring an exposed nail design, the fixing space is adjustable from 250mm to 1000mm.

Structural Integrity & Joints
The exposed nail design with split joints in our sandwich roof panels is widely utilized in industrial and commercial sectors. Their ease of installation and low maintenance requirements make them a cost-effective option for modern construction projects, promoting sustainability and operational efficiency.
Premium Surface Materials
Our panels offer multiple customizable surface steel materials and color choices including PPGI, Stainless Steel, and Embossed Aluminum.
PPGI (Prepainted Galvanized Iron)
PPGI features a galvanized steel base coated with a specialized paint layer for excellent corrosion resistance. It is lightweight, available in various colors, and environmentally friendly. With a long service life and minimal maintenance, it is ideal for roofing and wall cladding.
Color Customization
We provide professional color customization services to meet specific architectural requirements.
Specialized Surface Options
For specific functional needs, we offer various alloys and metals:
Ti-Mg-Zn-Al Alloy
Embossed Aluminum
Stainless Steel (SUS304)
Advanced Performance Coatings
PPGI can be enhanced with advanced coatings to extend performance:
- PVDF (Polyvinylidene Fluoride): Exceptional resistance to UV radiation and chemicals; ideal for outdoor architectural projects.
- HDP (High-Durability Polyester): Superior scratch resistance and protection against corrosion in industrial environments.
- EP (Epoxy Polyester): Excellent adhesion and chemical resistance, perfect for indoor environments.
Why Choose PIR/PUR Sandwich Panels?
- High Thermal Insulation: Low thermal conductivity (~0.022-0.025 W/m·K) minimizes heat transfer.
- Lightweight: Simplifies handling and reduces structural load requirements.
- Moisture Resistant: Closed-cell structure prevents mold, mildew, and water absorption.
- Durability: Resistant to UV radiation, physical impact, and chemical exposure.
As industries prioritize energy efficiency, PIR/PUR panels remain the cornerstone of contemporary roofing. By investing in these solutions, businesses optimize operating costs while minimizing environmental impact.
Frequently Asked Questions (FAQ)
Q What is the difference between PIR and PUR panels?
PIR (Polyisocyanurate) offers higher fire resistance (B1 rating) and slightly higher density than PUR (Polyurethane), which carries a B2 rating. Both provide industry-leading thermal insulation.
Q What is the minimum roof slope allowed?
Thanks to the 36mm crest height and three-wave design, these panels support a minimum roof slope as low as 3%.
Q Which surface materials can I choose?
Available options include PPGI, Stainless Steel (SUS304/201), Embossed Aluminum, and Ti-Mg-Zn-Al alloys, with optional PVDF or HDP coatings.
Q What are the standard dimensions?
Standard thickness is 100mm with an effective width of 1000mm. Lengths can be customized from 1m up to 18m to fit your specific project needs.
Q Are the panels suitable for cold storage?
Yes, their high thermal insulation and moisture-resistant properties make them an essential choice for cold storage and refrigeration facilities.
Q Can I request a custom color?
Absolutely. We offer full color customization for PPGI surfaces to match your branding or architectural design requirements.
