Josko's first all-glass system in uPVC was created in combination with perfect matching uPVC/aluminium windows from the Safir and Topas series: For the first time, you can have a contemporary all-glass design with the inexpensive material PVC. Just as with the wood/aluminium fully glazed system Platin Blue, the slim frames are equipped with weather-resistant aluminium on the outside. Thus both systems can be combined in a single unit, which is a clever architectural solution at a surprisingly affordable price.
