Depron

Depron
Other Names:

Extruded Polystyrene, XPS.

Description:

Depron is a particular type of extruded polystyrene foam (XPS), readily available in Europe where it is used for thermal insulation under wallpaper. It is available in sheets of various thicknesses and its big advantage is that it has a sealed surface which makes it very easy to finish and adds considerable strength. It is not so easy to obtain in the US in sheet form though if you want to see what it looks like the moulded meat trays you find in the supermarket are very similar material (and very useful themselves if you can get hold of some fairly large ones).

See also Foamboard - similar but with paper covering.
