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.

Frequently Asked Questions
QWhat is the difference between PIR and PUR sandwich roof panels?
PIR (Polyisocyanurate) has a higher fire resistance rating (B1) and slightly better thermal performance, while PUR (B2 rated) offers excellent insulation at a more economical cost. Both offer high performance for industrial use.
QWhat is the minimum roof slope for these panels?
Our panels support a minimum roof slope as low as 3%, enabled by the three-wave crest design (36mm height) which ensures effective water drainage.
QWhat surface materials can I choose?
We offer PPGI, Stainless Steel (SUS304/SUS201), Embossed Aluminum, and specialty alloys like Ti-Mg-Zn-Al, with various protective coatings like PVDF or HDP.
QAre the panels customizable in size and color?
Yes. Panel lengths can be customized from 1m to 18m, and we provide a wide spectrum of colors for PPGI surfaces to match your project's aesthetic requirements.
QHow does the installation process work?
The panels feature an exposed nail design with adjustable fixing spaces (250mm to 1000mm), making the installation process fast, flexible, and cost-effective.
