Most SUPs worldwide are not made to withstand 45 or 50 degrees under the sun as excessive heat increases the internal air pressure, often exceeding the limit of 15 psi and leading to small or large air leaks. Viking SUPs are manufactured based on Welding Rail technology, which increases resistance to internal pressure up to a maximum of 25 psi.
This technology allows for the mechanical welding of PVC layers (Welding Rail Tech) without the use of glue, achieving the fusion of two surfaces into a single, solid structure. This significantly improves the durability of the SUP, especially on the sides of the board (rails) where the two surfaces converge and where the highest pressures occur. This technology, presented for the first time in Greece, exponentially enhances the mechanical properties of the SUP, especially its resistance to high temperatures.
Additionally, the reduction in glue usage makes the SUPs odorless and increases their ecological footprint. Further protection from high temperatures is provided by the internal UV radiation protection coating.
