What sets Josko apart ...
All-round service

Prospective customers enjoy the high level of service already at their first time at Josko, due to the excellent advisory expertise – and also later when the site measurements of windows and doors are taken. We do not leave things to chance so that there is no risk for the customer.

What sets Josko apart ...
Vision and foresight

Even after years you can still rely on the existence of local service contacts and the availability of spare parts. Josko acts sustainably also in economic terms and has always had a positive balance so far.


What sets Josko apart ...
Passion for wood & environment

We care about our raw materials‘ origin. The wood we use comes from regional and sustainably cultivated woods and, therefore, we avoid thousands of unnecessary kilometres of transportation. With our know-how about processing and surface treatments we turn this fantastic raw material into gorgeous products.

What sets Josko apart ...
Design meets quality

Very often you have to choose between a beautiful look of windows and doors and a high quality in terms of heat insulation, security, etc. Not with Josko products – we offer a great look as well as best quality. Our high design standards in all product categories have already been awarded the RedDot Design Award and other well-known awards.

What sets Josko apart ...
Sustainable production processes

Most of the energy we need for our production comes from our own biomass power plant that we, in turn, fire with waste wood from the production.
