Creating the magic board
At Joistik Surfboards we use only premium blanks, highest quality fiberglass and resin, and work with Australia's best craftsmen.
Polyurethane construction (PU) uses traditional materials and laminating techniques to produce a strong, consistent surfboard with a high quality finish. The materials are robust, stable, and reliable to work with. Joistik PU boards are made using a polyurethane Core Industries foam blank with a plywood veneer stringer (others available).
After the board is shaped it is glassed at The Glass Lab using a premium polyester resin and Hexcel fibreglass cloth. These boards feature a flex pattern controlled by a high-grade timber stringer and will feel very reliable under your feet. PU construction will perform in all surf conditions and can be adapted to suit a wide variety of surfboard models.
Carbon fibre patches can then be added to the tail to prevent the rail/tail from excess wear and tear, as well as carbon fibre tapes along the bottom stringer to harness energy through turns and provide improved feedback from your board.
The result is a light, white high performance board that looks insane and surfs great too. PU construction is great for everyday use and performs in all types of waves and conditions.
Premium grade EPS (Expanded polystyrene) foam is glassed with epoxy resin to create a strong, light, responsive board. EPS advantages include reduced weight, increased buoyancy, strength and floatation. An EPS board can result in improved paddling speed, buoyancy and manoeuvrability most notably in smaller surf.
Joistik Surfboards use premium grade US Blanks or Marko EPS foam cores with veneer stringers which are glassed by Sel Surf or the Glass Lab using epoxy resin systems.
Epoxy resin is a healthier alternative to polyester as epoxy emits fewer volatile organic compounds than polyester resin, which means a decrease in harmful chemicals in the environment. EPS foam is also known for it’s great durability ensuring your board lasts a long time.
Karboload is a unique epoxy layup on stringer-less EPS foam that utilities our exclusive Y-Flex technology. With Y-flex, the central carbon bottom strip splits at the leading edge of the side fins and flares out in a “Y” shape towards the rail (at specific measurements, depending primarily on the fin setup).
The Y-Flex bottom harnesses the energy through the turn and carve like other bottom carbon strips, but where it differentiates and excels further is by additionally channeling the linear flex energy along the bottom, to transverse forces and flex through the tail third of the board. The energy feedback, acceleration, speed and liveliness through not only the turn, but more importantly the turn transitions (a result of the differing pressures between leading and back foot) are immediately noticeable and still allow a parabolic, uniform and tapered release of the energy through the more flexible tail.
We balance this with various options on the deck, such as single carbon strips or half deck strips (or none). The most popular option however are the dual carbon tape strips on the deck, positioned at a specific measurement apart (under the heels and balls of the feet), parallel and running from nose to tail. These dual carbon deck strips optimise torsional twist by controlling and utilizing the energy harnessed from torsional twisting along the length of the board.Read more
