Maximum glass. Minimum frame.
A window made entirely of glass without a frame? Not even we can offer that (yet). But our window variants with glass that covers the sash frame – Cristal for the interior, Nova-line for the exterior – come very close to this dream. Without any compromise in terms of functionality. Why is it that only Finstral offers this? Because we make practically everything ourselves. Developing frame profiles, producing insulation glass, setting installation standards. The result of this interaction is maximum glass, minimal frame – and always perfect functionality.
