Products Description
Polyurethane (PUR) and Polyisocyanurate (PIR) are the multifunctional foam core material widely used in various industries due to its excellent thermal insulation properties, mechanical strength and moisture resistance. Seamless insulated exterior siding sandwich panels are made with a rigid foam core sandwiched between two layers of durable facing material, typically made of metal or other alloy composite materials. The seamless design improves the overall performance and longevity of the structure by eliminating joints and joints, common weak points in traditional wall systems.

The Joint
The complex design of split joint of the sandwich panels are widely used in industrial, commercial, and agricultural buildings, including warehouses, cold storage facilities and manufacturing plants.
This kind of complicated joint make the panels connect to each other tightly and seamless, when showing a beautiful appearance and maintain the insulation at the same time. Also the ease of installation and low maintenance requirements make them a cost-effective option for modern construction projects, helping to increase sustainability and efficiency.

➤ Extra Coating Options
-
1
PVDF (Polyvinylidene Fluoride): Exceptional resistance to UV radiation, chemicals, and weathering with color vibrancy.
-
2
HDP (High-Durability Polyester): Superior durability and scratch resistance for high-traffic environments.
-
3

Advanced Seamless Insulation Technology
PIR/PUR seamless insulation exterior wall panels represent a major advancement in construction technology. Their combination of energy efficiency, moisture resistance, durability, aesthetic versatility, and ease of installation make them an attractive choice for modern building projects.
When installed in a cold storage facility, these panels create a barrier that minimizes heat transfer from the external environment to the interior space. This is critical to maintaining low temperatures, as even small fluctuations can cause temperature-sensitive products to spoil. The outer metal layer not only provides structural support but also protects the foam core from physical damage and environmental exposure.

Frequently Asked Questions
What is the difference between PUR and PIR foam core sandwich panels?
PUR (Polyurethane) and PIR (Polyisocyanurate) are both rigid foam materials. PIR panels have a higher isocyanurate content, providing superior fire resistance and slightly better thermal performance compared to PUR.
What thickness options are available for the sandwich panels?
Standard thicknesses include 100mm, 120mm, 150mm, and 200mm. Effective widths range from 920mm to 1000mm, and lengths are customizable to project needs.
What surface materials and finishes can be customized?
We offer PPGI, Stainless Steel (SUS304/SUS201), Embossed Aluminum, and alloys like Ti-Mg-Zn-Al. Coatings like PVDF, HDP, and EP are available for extra protection.
Are these panels suitable for cold storage facilities?
Yes, they are highly suitable due to a low heat transfer coefficient (≤0.024 W/[m·K]) and seamless Cam-Lock joints that prevent thermal bridges.
How does the Cam-Lock joint system work?
The Cam-Lock mechanism allows panels to interlock tightly without visible fasteners, ensuring continuous insulation and a clean, modern appearance.
What is the fire resistance rating of these panels?
Our standard panels carry a B2 Grade fire resistance classification. Enhanced fire-resistant formulations are available for projects with stricter safety requirements.
