This homogenous, very fine pored and firm foam not only has an especially high insulation potential but is also an alternative colour to the other rigid foams that are normally used in model making. Because of its dark grey colour, this foam offers a less contrast rich play of light and shadow than the white version but when cut properly it looks a lot like cement. When used on a black foundation, it really stands out in an unusual way and achieves a really interesting effect. As far as its fine pores and its cutting edges go, it can be used in combination with the bright blue, white or ivory coloured rigid foams without any problem.
