PU/PIR Sandwich Wall Panel
- Polyurethane sandwich panel with polyurethane foam cores meet the strictest heat insulation requirements, while also complying with the required insulation properties and maintaining a good bearing capacity.
-
PU/PIR Sandwich Panels are composed of 3 layers, the external and internal is two dyed Galvanized or Aluminum corrugated plates, and core high density POLYURETAHE foam. Thanks to their properties the panels may be applied in object that require very high fire resistance, PU sandwich panel is the most effective acoustic materials used on construction.
Take the 50 mm thick PU sandwich panel for example and the panel can absorb the sound over 30 db/m2.Widely used in the steel structure factory building, activities room, roof, wall, air clean room ceiling and partition.

Specifications
PU/PIR sandwich panels are widely used for external walls and internal partition walls in industrial and commercial construction. They can be installed vertically or horizontally on single- or multi-span steel frame structures, providing excellent thermal insulation, fire resistance, and structural durability.
Typical applications include:
- Industrial buildings and factories
- Steel frame structure buildings
- Warehouses, storehouses, and logistics centres
- Commercial buildings and offices
- Fire-rated and safety-critical structures
- Agricultural facilities and storage
- Sports halls and recreational centres
- Cold storage and refrigerated facilities
These panels offer a versatile, cost-effective, and energy-efficient solution for modern construction projects, combining high insulation performance with quick and easy installation.
