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.

Seamless Joint Design

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

What is the difference between PUR and PIR foam core sandwich panels?
PUR (Polyurethane) and PIR (Polyisocyanurate) are both rigid foam insulation. PIR contains a higher proportion of isocyanurate, providing superior fire resistance and slightly better thermal performance, making it ideal for safety-critical applications.
What thickness options are available for these panels?
Standard thicknesses are 100mm, 120mm, 150mm, and 200mm. Custom thicknesses and lengths can be manufactured according to specific project requirements.
Are these panels suitable for cold storage facilities?
Yes. The excellent thermal insulation and seamless cam-lock joint design eliminate thermal bridges, making them perfect for maintaining the strict temperature controls required in cold storage.
What is the fire resistance rating?
Our sandwich panels meet the B2 Grade fire resistance standard, ensuring compliance with safety regulations for industrial and commercial buildings.
Can I customize the color and surface profile?
Absolutely. We offer various profiles (Miro, Smooth, Linear, Embossed) and a wide range of PPGI colors. Custom color matching services are also available upon request.
