A core board with two sides capable of accepting application of inks, paint, markings, lettering, design and glues, as well as being suitable for cutting and mounting, having at least three layers, comprising:
- an inner layer of polystyrene or other polymer material, having a density less than approximately 0.10 g/cm3 and thickness less than approximately 300 millimeters;
- said inner layer positioned between a first outer facing layer means and a second outer facing board layer means, on opposite side of the inner layer from the first outer facing layer means;
- said first outer layer means and said second outer facing layer means each having a generally flat surface further comprising at least one outer layer adapted for accepting application of inks, paint, markings, lettering, design and glues, as well as being suitable for cutting and mounting;
- and
- said core board having a basis weight of less than 500 g/m2.
