Polystyrene is the now old type, of voidfill, due to more evironmental responsibility being taken.
We now recommend either :-
Greenfill is the cost effective alternative to polystyrene loosefill. This is a reasonably heavy duty void fill.
Eco Flow is a new bright white biodegradable product made from starch. It is odourless,dust free and around half the weight of other starch based loosefills.
