Fire-Performant PU Sandwich Panels for Building Cladding

PIR is a foaming material with a cross-linked structure formed by using different ratios of isocyanate and polyol and adding different catalysts and additives on the basis of polyurethane foam. It contains more isocyanate groups in its chemical structure. PIR foam is flame retardant, has low thermal conductivity, is lightweight, has high bending strength, does not absorb water, and does not rot.

Product Advantages

1. Fire Safety

These PU sandwich panels feature a fire-retardant core that slows flame spread and limits smoke emission. They meet international fire safety standards, providing reliable protection for commercial and industrial buildings.

2. Thermal Efficiency

The polyurethane core offers excellent thermal insulation, significantly reducing heat transfer through walls. This lowers energy consumption for heating and cooling, cutting operational costs throughout the building's lifespan.

3. Lightweight Construction

These cladding panels are lightweight yet rigid, reducing structural load and foundation requirements. They allow for faster installation with fewer workers and lighter lifting equipment on site.

4. Weather Resistance

The panels resist moisture, UV radiation, and temperature fluctuations without warping or degrading. This ensures long-term dimensional stability and maintains the building envelope's integrity in diverse climates.

Packing & Delivery

☆ Packing

Seaworthy packing standards:

Start with the large and heavy items and load them on the floor against the front wall of the container. Continue loading heavier items on the floor and towards the front of the container, placing lighter items on top. Pack the items tightly so nothing moves.
