Wind energy: rotor blades and nacelles. For many years we have been supplying our wind energy customers with reinforcing materials for increasingly longer rotor blades and larger wind turbines. On the one hand, this allows the efficiency of the turbines to be increased, while on the other the lightweight construction facilitates transportation of turbine components to areas that are difficult to access – for instance when developing offshore wind farms on the high seas. In such situations our products can withstand even the most hostile of environmental conditions.
