| How we make a Proof board |
| |
|
| The Core |  | |
At the heart of a modern high performance board is the expanded Polystyrene core. To achieve minimum weight and optimum working characteristics, the core should be kept dry as possible. The low humidity at our Gran Canarian board factory provides the ideal conditions to achieve an extremely low humidity lightweight core. |

|
Cutting |
|
Special cutting machines, developed by Carlos Sosa, allow us to simultaneously produce up to nine blanks with identical scoop-rocker lines The board outline is cut using stencils and our special Proof Hotwire production system. |
| Vacuum Bonded Bottom Sandwich |  | An extra strong bottom sandwich is vacuum bounded to the core using specially selected glass fibres. Vacuum bonding the bottom sandwich ensures maximum strength combined with minimum weight. |

 |
Mast and Fin Box |
|
The mast and fin box are formed using a high-density sandwich blocks. The extra strong blocks give strength to those all-important high-stress areas. |
| Laminated Deck | 
|
 | The deck is formed using a flexible sandwich, vacuum bonded to the core. The sandwich is created using closed-cell Polystyrene, bonded with woven carbon fibres and glass fibres. For added strength, the deck and bottom sandwiches are carefully bonded together, thus producing a genuine Monocock construction. |
