Optimised insulation and statics combined with a delicate window look
The perfect combination of design and material with high requirements for thermal insulation protection and burglar resistance: The groundbreaking high-end Janisol HI window system enables the best static properties combined with excellent Uf values thanks to its newly developed composite system.
Another plus: the basic depth of 80 mm ensures the easy use of double and triple-pane insulating glass. This means that large-sized window and door elements with heavy glass infills can be safely implemented - while maintaining minimal sightlines.
