Creation of windows nowadays is a multidisciplinary process, which is primarily based on the technical and technological development of all components involved in it. However, observing windows as architectonic elements represents a starting point of the design analytical stage. The doctoral art project by Marija Petrovic, with PhD Jelena Ivanovic Vojvodic as her mentor, Design of windows in architecture, case study of wood-aluminium windows, considers windows through the history of architecture,
and identifies the ratio of windows and illuminated areas in the context of the use of daylight and aesthetics of contemporary architectonic façade, examines the sustainability of design in accordance with the technical and technological progress and reflects on the latest tendencies of sustainable architecture. As a conclusion of the conducted research, a continuous window pattern has been defined, and the window system STRUKTURA (structure) has been designed.

CONTINUOUS WINDOW SYSTEM
STRUKTURA is a continuous window system, which ranks the windows among those architectonic elements which maintain consistency of architectonic details. The genesis of architectonic development, clearly demonstrates changes in the window pattern in the 20th century; the window ceases to be only a framed and finite form, and rather becomes a glass barrier which is bounded only by the height of a room. It is created as a composite window system, employing three key materials: fiberglass, aluminium and wood. The synergy of their properties makes it possible to create large glass walls. The system entails the use of triple glazing, which accounts for the excellent thermal insulation characteristics. The arrangement of materials on the interior signals a clear distinction between the sections that can be opened versus the fixed lights, creating in this manner a harmonious aesthetics of order and rhythm.

The window system STRUKTURA was created as a response to a new design task. By establishing the maximum height of a window partition of 280 cm, observing the established continuous window pattern, preserving and implementing technical and technological achievements and by aspiring to achieve the sustainable architecture goals, the STRUKTURA system creates a characteristic aesthetics in the spirit of contemporary architecture.
The design of the STRUKTURA elements is based on the idea that a detail is a part of the entire architectonic whole. Through the simplicity of form, it emphasizes the order, rhythm and harmony in architecture, in a way which separates the elements of the rhythm from the operative elements. It can be a lone window in a bearing wall, but also a window within a glazed composition, extending into a long horizontal series of elements.

MATERIALS OF STRUKTURA
The first aspect in the selection of materials involved in creating STRUKTURA is the aspiration of contemporary architecture to enlarge window composition with simultaneous drastic reduction of cross-sections of window verticals and horizontals, stemming from the desire to lose all boundaries.
The second aspect constitutes the contemporary tendency of humanity to conserve natural resources and reduce emissions of harmful gases through the reduction of the heating and cooling energy consumption.
The third aspect is the aesthetics of the window that acts in symbiosis with the architectural expression. It tends to simplify the shapes and emphasize material values.
The fourth aspect relates to material processing requirements imposed by standardization of hardware and grooves for fitting of hardware, as well as other necessary profiling of cross-sections of window verticals and horizontals.
In that sense STRUKTURA, as a composite window system consists of three key materials:
BASIC DETAILS
The window system STRUKTURA represents a symbiosis of the planar structural grid of uniform dimensions of cross-sections of its vertical and horizontal partitions and operable window frames. The distinction of these two elements is effected by using different materials for vertical and horizontal elements, and for the window frame.
STRUKTURA is a composite window system where three materials assume the primary roles: aluminium, fiberglass and timber.
Vertical and horizontal partitions of the planar grid are made of composite sections constructed of: fiberglass profiles having the role of structural components of the system; aluminium profiles on the outside and timber profiles on the inside.
THERMAL DESIGN OF
THE WINDOW SCHEME
Considering that architectural requirements tend towards a drastic reduction in the window frame dimensions, with a simultaneous increase in glazed areas, the conclusion is that the glass takes over a greater role in protection against excessive heat losses. Triple glass in combination with wormedge profiles can provide a heat transfer coefficient of only 0.5 W/m2K.
It is for these reasons that the system STRUKTURA includes the use of triple glazing with, at the same time, small frontal dimensions of window verticals and horizontals, as well as of the operable frame itself.
