WPC decking has become a widely used product in the Spanish market. Initially, solid profiles from American manufacturers like Fiberon and Timbertech dominated the market. However, from 2010 onward, cheaper hollow profiles produced in China or the region became more popular and now hold an estimated 80% market share. Both hollow and solid profiles are produced locally by Spanish and Portuguese manufacturers, with hollow profiles being more common. The dominant materials for WPC decking are PVC and polyethylene.
