Windows and doors from KRONE are produced in the most durable woods from recognised suppliers. The use of heartwood makes environmentally damaging impregnation unnecessary. Instead, we surface our wood with an environmentally friendly treatment. Along with the use of super low energy glass the future looks bright - from production to end-user and our common environment.

Wood has an amazing quality that is better suited than any other material to manufacture windows and doors. For us it is not indifferent where our supply of wood is coming from. Therefore we get our wood from controlled forestry, where the rate of replanting is greater than that of felling.
