Sashless window – Clara DUO

The all-glass window without relief
for a modern and refined aesthetic

Thanks to the masking of its components and mechanisms, Clara DUO windows offer:

– Panoramic views thanks to a large glass surface
– A clean design decreasing the border between your interior and your exterior
– Optimization of the presence of natural light in your home or office

filigree design

The elegant, continuous glass surface of a Clara window allows the boundaries between inside and outside to merge because the casements are flush, constructed without steps and edges. Functional components such as the frame, the locking mechanism, fittings or seals are subtly concealed behind narrow, surrounding enamel strips.

(Almost) boundless
design freedom

Every Clara window is a unique item that adapts perfectly to people’s personal preferences in terms of interior design and architectural style. The entire RAL colour palette is available for the design of the frame construction as well as the enamel edges inside and out. The window handles are of course freely selectable.

Living comfort
with safety benefits

Clara windows are a prime example of what modern windows can contribute towards our feelings of personal comfort. The outstanding thermal insulation value of 0.75 W/m²K guarantees cosier rooms with a maximum feel-good factor. The innovative frame design on the inside also ensures excellent sound insulation. Window cleaning also becomes child’s play due to the fact the window frames and casements are aligned with one another. No corners and edges, no window seal in which dirt can accumulate.

A Clara window can be levered out only with difficulty thanks to the continuous glass surface and concealed fittings. Moreover, they are made of specially hardened glass panes.

In addition to their elegant appearance and optimum thermal insulation properties, you also benefit from a window that offers outstanding burglary protection.
