Hi guys,

I'm a big fan of using bead board as a bounce material, but sometimes it can be difficult when the gaffer in a new country doesn't know what a bead board is.
Sometimes, the material I end up with is a different, harsher material, which renders light less soft.

So, I was hoping someone in here could help me clear up my confusion between the many names,

Is there anywhere I can read and get good information about the difference between the following?

-styrofoam

-polystyrene

-- expanded polystyrene

-- extruded polystyrene

-poly (I'm guessing it is short for polystyrene)

-beadboard

-foam core

 

Any help would be much appreciated,

Thanks,

Extruded Polystyrene is Depron.

Expanded Poly and beadboard are the same.  White one side, usually foil covered on the other, various thicknesses.  It's a type of insulating sheathing.

 

Foamcore

Thanks guys,

So from what I can see,

Bead board = Styrofoam Board = Expanded Poly
Depron = Extruded Polystyrene

Does that look correct?

Foam Core.. is still a bit unclear 

I have some pictures, do you know which is which?

Those all look like  a version of the Beadboad-Styrofoam.

 

Foamcore is a smooth surface. It is usually used as a backing for mounting artwork, photos and anything else you need displayed.
