The question that is often asked to me when talking about Surf Style boards is simply what is the difference between a board with a PU (Polyurethane) core and another one with an Expanded Poly Styrene (or Styrofoam core )?
When we talk about PU and EPS we only talk about the foam that form the core of the board, we will see later the other ingredients that make up the finished board.
Today some brands prefer an EPS / Epoxy manufacture to the traditional PU / Polyester but it would seem more a question of fashion than of real advantage. Some pro surfers prefer, depending on the “surfing” conditions one or the other type of boards that each have their advantages and disadvantages.
Let’s first take a look at a classic board construction, a polyurethane foam core laminated with fiberglass and polyester resin (PU / PE). These boards are generally more affordable than EPS / Epoxy boards, are slightly heavier and have a little less buoyancy than the EPS ones, allowing the rails to sink better in the water for better turns. PU boards also have a more natural flex that many surfers prefer.
At Black Revolt Wakesurf we offer the 2 types of constructions for your “Surf Style” board . The EPS / Epoxy boards cost 100 € more than the PU ones because of the extra material and time of shape/sand.
