Product Description

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.

Frequently Asked Questions (FAQ)
QWhat is the difference between PUR and PIR foam core?
PIR has a higher isocyanurate content, providing superior fire resistance and slightly better thermal performance at elevated temperatures compared to PUR.
QWhat thickness options are available?
Standard thicknesses are 100mm, 120mm, 150mm, and 200mm. Custom thicknesses can be arranged for specific project needs.
QAre these panels suitable for cold storage?
Yes, they are highly suitable. Their high-density core and seamless Cam-Lock joints minimize heat transfer and prevent moisture ingress.
QWhat surface materials can be customized?
Options include PPGI, Stainless Steel (SUS304/201), Embossed Aluminum, and various alloys with optional PVDF or HDP coatings.
QHow does the Cam-Lock joint system benefit the project?
It ensures a tight, gap-free connection that maintains continuous insulation, simplifies installation, and creates a uniform visual appearance.
QWhat is the fire resistance rating?
Our standard panels carry a B2 Grade rating (self-extinguishing). Higher fire-retardant versions can be specified for sensitive projects.
