=== Composite Sandwich Construction ===
The Composite Sandwich type of board construction became popular among garage shapers and later, major manufacturers, during the 1990s and 2000s. This construction method entails hand- or machine-shaping a foam blank from EPS foam and then vacuum-bagging or hand-laminating a more dense layer of foam, wood, or carbon onto the bottom and deck of the EPS foam core, usually separating the two layers with lightweight fiberglass cloth (2&nbsp;oz&nbsp;pr.&nbsp;sq.yd, or 70&nbsp;g/m<sup>2</sup>) or other composites cloths. This can also be accompanied with parabolic rails made of balsa or other buoyant woods, carbon, or other high-density materials. This blank construction is then laminated with epoxy resin and fiberglass or other composite cloth as any other surfboard would be, by hand or via vacuum bag.

The construction is referred to as a sandwich as it consists of the top skin, fiberglass or other composite cloth, the EPS core, fiberglass or other composite cloth, and the bottom skin, the cross section of which appears as a sandwich with the different layers. Firewire Surfboards pioneered this technology for the mass-produced surfboard market beginning in 2006.

Soft skin construction, such as Cush or Spacestick boards, adds an additional soft shell skin to the outside of a sandwich construction board.  The soft skin is vacuumed to the cloth and epoxy so that the soft shell is exposed--- meaning the hard glass and resin are protected inside, and under, the soft cush skin.
