Technology

ERTHAFLEX is the most responsive technology of our production. It was developed for the RAD Family but it can be used in other board families as well to create interesting, promising “hybrid monsters”.

The core is made of 18-20kg/m³ recycled EPS, combined with an active flex system which is the result of the ERTHA SPINE on the deck and an ampliTex™ Fusion flax fiber reinforcement on the bottom. Just as in the best athletes prosthesis, nothing beats the flex and responsiveness of laminated wood!

The NATURAL FIBER RECYCLED EPS boards are eco-friendly, high performance crafts. The core is 18-20kg/m³ recycled EPS, laminated with AmpliTex™natural flax fiber from our friends at BComp. The shapes, obtained by 3D scanning, have micrometric precision thanks to our CNC machine.

The combination of natural fibers and Entropy Sap One II Resin gives these boards an easy, gentle flex. If you don’t like EPS boards for their excessive vibrations, these boards will make you change your mind.

The ERTHA WOODSKIN EPS boards are high performance, ecological wave riding machines, built around a 18-20kg/m³ recycled EPS core, laminated with a tri-axial micro-sandwich skin of certified sustainable Paulownia wood.

Micrometric precision is guaranteed by our high range CNC machine. The wooden skin is vacuum laminated using eco-friendly Entropy Sap One II Resin. Light and extremely durable, Paulownia wood is not only the ideal armor for your board, but the reason of superior flow itself.

ERTHA ECO HOLLOW is arguably one of the most advanced wood hollow surfboards technology, a construction style that dates back to the 1920s and which is coming back strongly on the line-ups for environmental reasons.

Under a layer of eco-friendly Entropy Sap One II resin lies the secret: each laser-cut element of the structure is perfectly optimized for elastic responsiveness and oriented to work accordingly to the wood fiber direction. We are experienced surfers, architects and carpenters!

An ERTHA ECO HOLLOW surfboard in a flat box. No need for tools nor any kind of building experience. The only things you need are a flat surface - any table will do! - and a little time.

The ERTHA DIY KIT is like a foolproof 3D puzzle: the ERTHA Scaffold allows you to build, without any room for human error, the model you have chosen. This is the most sustainable option: build your own surfboard using renewable materials.
