Which frame material is used depends on factors such as the type of building, the personal taste of the builder and the budget.

But the environmental damage caused by the manufacture, use and disposal of the products also plays a decisive role. With a market share of 54 percent, the most important material for window production in Germany is PVC. In Europe, the proportion of plastic window constructions has increased from 24 to 38 percent over the last ten years.

Wood has become increasingly important as a building material in modern architecture. There are good reasons for it:
