|  | Why Polystyrene Foamboard?
Polystyrene foamboard has a number of advantages over polyurethane boards, or "polyboards". Firstly, the closed-cell structure of polystyrene gives the foam a "memory" which enables it to recover its shape after being compressed. Polyurethane does not have this "memory", so when die-cutting polyboard the edge remains compressed. Our foamboard gives a clean straight edge.
Another advantage is that while polyboards turn yellow with age, our foamboard has been treated to resist UV yellowing.
Finally, polystyrene does not produce any harmful gasses during its manufacture, and is fully recycleable. Polyurethene boards are not.
The only limitation of polystyrene foamboard is that it cannot be used in conjunction with solvent based paints and glues. If you wish to use these then we would reccomend using polyurethene boards. |
