Glass fibre reinforced polyester resin material is made with the so-called pull-trusion technique. Pull-trusion is a non-stopping process of glass fibre wires pulled through a bath of polyester resin that harden in a matrix afterwards to get their final shape. Main advantages of this material are its strength, corrosion-durability and its light weight. We use it for the Sticks space divider, Extremis prefers glass fibre sticks instead of wooden sticks. The material that is lost for producing the sticks in wood would be a minimum of 65%, what is way too much and not following the Extremis philosophy.

The only disadvantage for glass fibre rods is they can cause splinters when you fiercely rub along them with your hands. The splintering is caused by the miniscule glass fibres that stick out of the polyester resin. When you would look at it with a magnifying glass you would discover the sticks are covered with tiny glass fibre hairs. Try to avoid rubbing the Sticks' rods with your bear hands, always wear gloves, when you assemble or move our Sticks space divider.

The fibreglass rods do not require special maintenance. They can simply be kept dustfree with a slightly damp cloth.
