Terrace windows

Large size for a beautiful view. Strong profile, steel reinforcement, reliable fittings and large  glass size allow Viknar’off to produce windows 6m wide and 2.8 m high. The maximum size is achieved due to the unique function of dry pasting of a double-glazed unit in the STV sash which is presented in Gealan profiles.

Parallel-sliding constructions that connects space of your room. Our windows are extremely easy to use – and despite the large size are easy enough to open or close even for a child.

Uncompromising security. Large windows for terrace may appear to be a weak point of the house, but strong reinforcement, reliable fittings with protection against burglary will safeguard you from uninvited guests.

Protection from cold and heat – a key function of the terrace windows. Viknar’off sliding systems provide reliable protection against the cold, dust and noise from the street. And with multifunctional Solar glass you will be protected from the excessive heat and spendings on air conditioning.

No barriers from Viknar’off. Thanks to the special Siegenia Barrier Frei threshold, there are no obstacles to movement, and excess moisture and dirt will not get into the room. For maximum comfort, we recommend installing a parallel sliding system with a drainage system.
