Windows and sliding doors made entirely of glass? Our all-glass models come unbelievably close to turning this dream into reality. Because the frame completely disappears behind glass. Whether on the interior (Cristal), exterior (Nova-line) or both (Nova-line Cristal) – the external outlines are pared down to a minimum. To deliver slim frames, full-area glass fronts and maximum daylighting to your home.
The sash frame of our windows or sliding doors can be made to disappear behind glass. On the interior only, on the exterior only or on both interior and exterior. These contemporary designs are combinable with all other materials: uPVC, aluminium or wood.

Typical window units combining several glass panels – some fixed, some openable – can use frameless window sashes to craft highly elegant compositions. Here, the sashes and fixed lights all feature well-proportioned frames to create a uniform external appearance. A solution purposefully used by architects.






For the customised design of your windows, Finstral grants you maximum design freedom: whatever your wish – whether glass in Khaki Grey or minimalist handles without a round rose – at Finstral, (almost) everything is combinable with everything else.
A restrained look also spells less care and maintenance. Covering the sash frame with glass results in fewer edges where dust and dirt can accumulate. This is both attractive and practical.
Do you just want to inspect, touch and try out our products? At the Finstral Studio, you will find a wide range of windows and doors. Along with expert answers to your questions.
Windows are investments for decades. Which makes intelligent design all the more important. The diversity of design and functional options is far greater than you can imagine.

At a glance.
Anyone seeking frameless windows will often be presented with non-openable units. Finstral’s ingenious solution for creating windows with an all-glass-look consists in skilfully concealing the sash frame behind the glass – on either interior or exterior. This enables you to enjoy the aesthetic of a frameless window, which you can nonetheless conveniently open at any time. Whatever you wish – whether filigree balcony doors or spectacular all-glass corners without visually obtrusive mullions – we will manufacture an inch-perfect frameless glass front to your exact specifications.
Quite the opposite: a minimalist look actually spells less care and maintenance. Covering the sash frame with glass results in fewer edges where dust and dirt can accumulate. This is both attractive and practical.
Finstral incorporates Plus-Valor double glazing as standard. For large glass fronts with high exposure to sunshine, we recommend one of our three solar protection glass types. Available as double-glazed and triple-glazed units, these prevent any overheating of the interior. All with a minimum loss of daylighting.

Each window is unique and the price depends on many different factors: size, materials, glass, security options etc. For a personalised quote, please contact us at finstral.com/contact.
