Polyurethane (PU) Insulation Panels
One-stop solution for your cold storage needs
Highly customisable UR® PU panels with a range of core thicknesses, finishes and joint systems — assembled vertically or horizontally for interior and exterior cold storage.
01
High insulation, modest thickness
PU foam delivers the same insulation as much thicker brick, wool or polystyrene — air and water cannot circulate inside the core.
02
Clip, cam and semi cam-lock
Tongue-and-groove clip-lock, cam-lock and semi cam-lock joints for clean wall and ceiling assembly.
03
SIRIM listed · Bomba approved
UR® PU is a certified and listed product by SIRIM QAS International, and tested and approved by Bomba Malaysia for commercial and industrial use.
Overview
Custom panels for real projects
Polyurethane panels are highly customisable. We have a range of core thicknesses, support finishings and panel joints to choose from. The rigid polyurethane foam is favoured for insulation panels because of its mechanical, chemical, biological and moisture properties.
Panels can be assembled by vertical or horizontal disposition and are suitable for interior and exterior applications — for restaurants, cold rooms, warehouses and industrial refrigeration fit-outs.
Advantages of PU foam
What UR® PU panels offer
Excellent insulating efficiency, easy installation and maintenance, aesthetically pleasing finishes, and durable construction for daily cold-room use.
- Food grade compliance
- Moisture and corrosion resistance
- Superior thermal performance — high insulation even with a modest material thickness
- High density mechanical strength — suitable for wall and roof applications
- Fire retardant — in a fire the foam does not drip or run, minimising flammable mass
- CFC free
- Air- and water-tight core — installation in all weather conditions
- Clip-lock, cam-lock and semi cam-lock tongue-and-groove joints
Applications
Where UR® PU panels are used

Insulation performance
Equivalent thickness for the same degree of insulation
PU panels keep insulation high even with a modest material thickness. Air and water cannot penetrate and circulate within the panel walls.

| Softwood | 140 mm |
| Fibreboard | 65 mm |
