Product Description

Products Description
Our PIR or PUR Sandwich Roof Panel features high thermal insulation values, lightweight construction, moisture resistance, and long-term durability. Designed for energy efficiency and ease of installation, these panels are a premier solution for industrial buildings, commercial facilities, agricultural structures, and cold storage applications.
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 effectively reduces construction costs while ensuring 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.

Advanced Coatings
To maximize longevity, several advanced coatings can be applied:
1
PVDF (Polyvinylidene Fluoride): Exceptional resistance to UV radiation and weathering; ideal for outdoor architectural projects.
2
HDP (High-Durability Polyester): Superior scratch resistance and protection against harsh industrial environments.
3
EP (Epoxy Polyester): Excellent adhesion and moisture resistance; perfect for indoor chemical-prone areas.
Coating Performance
Core Benefits
🌡️
High Thermal Insulation: Low thermal conductivity (approx. 0.022–0.025 W/m·K) ensures maximum energy savings.
⚖️
Lightweight Construction: Simplifies handling and reduces the total structural load on the building frame.
💧
Moisture Resistant: Closed-cell foam structure prevents water absorption and mold growth.
🛡️
Extreme Durability: Resistant to chemicals, UV radiation, and physical impacts for a long service life.
Frequently Asked Questions
Q: What is the difference between PIR and PUR sandwich roof panels?
PIR (Polyisocyanurate) offers a higher fire resistance rating (B1) and slightly better thermal performance (≤0.022 W/m·K) compared to PUR (B2, ≤0.024 W/m·K). PIR is often preferred for projects with stringent fire safety codes.
Q: What thickness and width options are available?
Our standard panels are 100mm thick with an effective width of 1000mm. Lengths can be customized from 1 to 18 meters to suit your specific project needs.
Q: Can these panels be used for low-slope roofs?
Yes, the three-wave crest design and 36mm crest height allow for effective drainage on roof slopes as low as 3%.
Q: What surface materials can I choose from?
Options include PPGI (Prepainted Galvanized Iron), Stainless Steel (SUS304/SUS201), Embossed Aluminum, and specialized alloys like Ti-Mg-Zn-Al.
Q: Are the colors customizable?
Absolutely. We provide comprehensive color customization for PPGI surfaces. You can specify RAL colors or provide samples for matching.
Q: What are the primary applications for these panels?
They are ideal for warehouses, cold storage, manufacturing plants, commercial buildings, and agricultural structures requiring high thermal efficiency.
