We offer replacements for your camper windows.

Welcome to Crack Ex

Your reliable partner for replacement windows for caravans and campers, regardless of the manufacturer.


We have been a recognized partner of Polyplastic (Rotterdam) for many years and specialize in supplying replacement windows for new and older camper vehicles. Thanks to our experience and our network, we are often able to deliver windows for caravans, motorhomes and camping vehicles that are no longer officially available for order. In recent years we have successfully carried out the security campaigns of Polyplastic (Bürstner, Knaus, Tabbert, Rapido, etc.), which have now been completed.
