Construction projects need to be completed on time and handed over free of defects. That means planners and designers have a lot of decisions to make. One of them is choosing the right construction materials. There are few other materials that meet the different requirements in the construction industry as flexibly as plastic. Plastics are increasingly replacing traditional materials such as wood and metal. Our materials are used, for instance, in the construction of long-lasting doors and window frames and resistant collision protection panels and help to prevent cold bridges.
