Product Construction
There are typically types of constructions in the surf Industry. Poly, Epoxy, and Sandwich Veneer constructions.
Poly boards are the most common board on the market. It is also called PU and fiberglass boards. Poly is short for polyurethane, the foam core that is used to shape the board. These boards normally have a wooden stringer down the center and is glassed with fiberglass and resin. Poly boards tend to have a softer flex allowing beautiful carves on wave. The feel of poly boards have made them the favorites on the surf market
Epoxy aka EPS boards are the rave in the surf industry. These boards differ from the core. EPS short for Expanded Polystyrene is the same foam found in coolers and styrene foam cups. EPS foam is then shaped and glassed and an Epoxy resin is applied, hence the name epoxy. Epoxy resin typically non-transparent giving it a distinct look. Epoxy boards have a few advantages over standard poly. Epoxy resin is much harder than the typical poly resin making it much more ding resistant. The foam on Epoxy board is less dense, so the overall weight of the board is decreased. The result is a lighter board and more buoyancy. This makes it easier to paddle and maneuver. Epoxy board also typically have stiffer flex providing a different, more floats, feel.
CSC
CSC ( PVC Veneer) is our proprietary technology. This construction have many benefits. It is nearly 20% lighter and 30% stronger than a epoxy board. On many of the shorter boards the stringers are not needed to maintain structure integrity further decreasing the weight. It is similar to many other sandwich designs, but it is far superior. We start with an EPS blank, then we hand shape it to the desired shape. From here on out is where it differs from other sandwich boards. Most companies use a mold which presses the PVC on. This leaves a small gap between the top PVC sheet and the lower PVC sheet near the rail. We, however, use a 3 mm PVC sheet that is slightly larger than the shape. Then we vacuum seal it on the board. This not only creates a better bond between the two foams, but the PVC overlap to fill any gaps. Then we hand finish the PVC and glass it.
