Nature is an important subject when it comes to classical living. Large area sliding elements from Josko are therefore available for these windows, just as in the Avant-garde and Modern ranges. They invite nature into your house and treat the senses to garden fragrances, the chatter of birds and fresh air. You can also open large areas of glass effortlessly with the technically refined lift and slide door systems RUBIN 78 and DIAMANT 89 from Josko tested for tightness by the Austrian Wood Research Institute. The Josko lift and slide doors are available in all materials and therefore harmonise with the window system of your choice.
Test passed with distinction.
Before being brought to market the Josko lift and slide doors Rubin 78 and Diamant 89 must pass many internal tests and await further developments. This stubborn attitude has paid off. Best values have now been obtained for resistance to air, heavy rain and wind in the tightness test carried out by the Austrian Wood Research Institute.
