Vitrafib are shot and thin monofilament glass fibers, manufactured from alkali-resistant glass. Millions of evenly spreaded fibers guarantee a multidirectional reinforcement system in concrete and chape which reduces microcracks to the bare minimum.

VITRAFIB 36/67 are long monofilament glass fibers, manufactured from alkali-restistant glass with a high strength, designed to reinforce the structure of concrete. Due to their brittleness, Vitrafib 36/37 is ideal for polished concrete floors.
