Polish window manufacturers increased their volume of exports by nine per cent to seven million units in 2017, while the value of exports has increased sixfold since 2014. These figures were revealed by the Polish market research company Centrum Analiz Branżowych (CAB) in its latest study, "Window market in Poland, 2018 edition". Polish manufacturers achieve the highest prices for PVC windows – EUR 241 per unit on average – in France. The price level in Italy and the Netherlands is generally very good, whereas in Lithuania and Latvia, for example, it is two and half times lower than in France. Wooden windows from Poland are most expensive in Ireland and the UK, according to the study, while aluminium windows cost most in Germany.
