🚀 Products Description
Our PIR or PUR Sandwich Roof Panel features high thermal insulation value, lightweight construction, moisture resistance, durability, energy efficiency, and easy installation, making it a popular solution for modern construction. These panels are utilized in a wide variety of applications including industrial buildings, commercial structures, agricultural facilities, and cold storage units.
📋 Product Details
Our PIR/PUR roof panels adopt a three-wave crest design with a crest height of 36mm, which significantly improves roof drainage and load-bearing capacity. This design reduces construction costs while ensuring superior thermal insulation. The roof slope can be as low as 3%. Featuring an exposed nail design, the nail fixing space is adjustable from 250mm to 1000mm.

🛡️ Advanced Coatings
Enhance performance and durability with advanced coating options:
- PVDF (Polyvinylidene Fluoride): Exceptional resistance to UV radiation and weathering; retains color vibrancy over time.
- HDP (High-Durability Polyester): Superior scratch resistance and protection against corrosion in industrial environments.
- EP (Epoxy Polyester): Excellent adhesion and chemical resistance, ideal for indoor applications.
🌟 Core Advantages
🔥
High Thermal Insulation: Low thermal conductivity (0.022–0.025 W/m·K) ensures maximum energy efficiency.
⚖️
Lightweight: Simplifies handling and installation while reducing structural load.
💧
Moisture Resistant: Closed-cell structure prevents mold, mildew, and water absorption.
🛡️
Durability: Resistant to UV radiation, chemicals, and physical impacts for a long service life.
Investing in PUR/PIR sandwich roof panels allows businesses to ensure building integrity while optimizing operating costs and minimizing environmental impact through efficient temperature control.
❓ Frequently Asked Questions
What is the difference between PIR and PUR sandwich roof panels?
PIR has a higher fire resistance rating (B1) and slightly higher density, making it better for fire-critical applications. PUR offers cost-efficiency with slightly lower density. Both provide excellent thermal insulation.
What is the minimum roof slope for these panels?
The panels support a minimum roof slope of 3%, thanks to the 36mm crest height which ensures effective drainage even at low pitches.
What surface materials are available?
Options include PPGI, Stainless Steel (SUS304/SUS201), Embossed Aluminum, and alloys like Ti-Mg-Zn-Al. Thickness ranges from 0.3mm to 0.8mm.
What lengths and thicknesses are available?
Standard thickness is 100mm with a 1000mm width. Lengths are fully customizable from 1 meter up to 18 meters.
What are the typical applications of these panels?
They are ideal for industrial and commercial buildings, cold storage facilities, warehouses, and agricultural structures.
What coating options are offered for PPGI?
We provide PVDF for UV resistance, HDP for high durability/scratch resistance, and EP for chemical and moisture resistance.
