Windows in the service of maximising the view
2018 / 09 / 26

„Windows in the service of maximising the view”

Frameless windows are favourite elements in houses built in modern and minimalistic styles, since, thanks to the nearly invisible frames, the external and internal spaces almost connect; in this way, nothing disturbs the view, and also natural light may flow into residential spaces through a greater surface.

It also seems at first to be an anomaly; “frameless” structures are frameless only in their names. In other words, frameless does not refer to the structure but rather to the view. In the first part of the last century, in the Bauhaus era, the need for transparency and increasingly skinny frame structures arose. Although the technical opportunities of that era allowed no large single glass surfaces to be manufactured, they were however tensioned efficiently with small divisions, in the desire for honesty. Then, as heat technology demand rose, peaking upon the explosion of oil prices, a downwards trend period started but, starting in the mid-nineties, designers and also customers looked for transparency and chose frameless structures and so this line is thriving again.

Today’s transparent systems have barely visible frames; however, their role is important, since they carry the glazing or another see-through filling material. It is important that these frames are resistant to weather changes and can also bear the mechanical load affecting them. In the Netherlands, customers look for extra-thin steel frameworks, while in other European countries professionals propose using aluminium or other special composite products. In the culture of floor to ceiling closing structures, due to the moving challenges posed by the heavy three-layer glazing, we prefer sliding doors combined with fixed elements, although in aluminium systems it is possible to manufacture tilt-and-turn structured products that are three metres tall. Frameless systems mainly aim to provide a greater surface for the user of the building, from which to enjoy a nearly undisturbed view.

It is important to emphasise that frameless systems represent a much higher price category than their traditional counterparts. In many cases, the minimalistic concept itself requires being able to see as large a glass surface on the adjoining walls as possible. The aim is to have as little painted or coloured border surface between the glass and the wall, and, if possible, the sun shade should also stay hidden. Many people like it when only the glass and nothing else can be seen on the wall. Of course, there are architects who do not like this line and agree with the view that if a structure has a function and if it is honest and this function is visible then this adds to the building. As Károly Lovász, Managing Director of the KAV, put it, the advantage of aluminium systems is that they are able to meet both demands: “At KAV, we believe in combining various systems. Where they fit, frameless systems should be integrated, and where they don’t, we try to offer another alternative that’s liked by the customer and the architect. Sometimes a customer would like to mix sliding and opening functions, and we seek to find a solution in any case. It happens that, in the design phase, it is forgotten that the building must be able to carry the load of these glass shields, weighing sometimes 800 to 1000 kg (stacked behind each other, practically in a thin line). And so the building is already ongoing when we meet the customer and it turns out that the engineering of the building will not bear the demands set. We therefore ask architects to consult us before preparing the engineering designs, when the sketch designs are available and the volume calculations are ready (insert link: https://www.kavaluminium.com/aktualis/a-kav-az-epiteszek-munkajat-is-segiti-53), to ensure that the building and we too, as professionals, are capable of fulfilling the customer’s expectations.”

A refined aesthetic for doors and windows
The popularity of the minimalist style in architecture is one of the reasons that aluminium doors and windows entered the family house sector. Applying the principle of “less is more” to architecture led architects and designers to use unique solutions and austere or transparent surfaces. In a minimalist home, simple shapes and forms help create an atmosphere of harmony, where space itself serves humanity.

Development by KAV of aluminium doors and windows with an all-glass look
Optivison© is unique in Hungary. (KAV is the only player in the small and medium-sized business sector to have developed aluminium doors and windows with an all-glass look for family homes.) Apart from KAV, no one among small and medium-sized enterprises has developed all-glass look aluminium fenestration for family houses. The system was designed to respond to the needs of our customers: we made the frame flush with the glass by rethinking the structure of tilt and turn windows and balcony doors. Our solution creates a ‘glass wing’ effect, making Optivison© systems the trend-setting doors and windows for modern family homes.

Those about whom who nobody ever talks, or the eminences of manufacturing preparation
KAV's customers come into contact with several of our colleagues in the bidding, preparation and construction processes in the course of a job. These are our sales and estimation colleagues, our technical and manufacturing preparation engineers, our project engineers, and then our installation specialists. It is very rare that the end-user comes into contact with the manufacturing preparation engineers. In this article, we’d like to describe the work of these professionals in connection with the Continental Golf Club construction project.

Rebirth of a Bauhaus villa
Rebirth of a Bauhaus villa
This year, the Bauhaus is 100 years old, and it is a great pleasure for us to take part in the renovation of a property displaying the marks of this school. When the Bauhaus appears as a description of a building, it is a guarantee of clean shapes, exciting spaces and quality materials. Even so, it is important to point out that although several Hungarian architects were in contact with the famous German school, there are hardly any Bauhaus buildings, in the strict sense, in Budapest. Péter Lenzsér, the architect, talked about how this building bears the hallmarks of style and how it is worth embarking on such a renovation.

Special KAV doors and windows in Költő Kert
MTVA's innovation magazine program, Novum, made a report on the special glass elements and door and window solutions of the 5,000 square meter Költő Kert villa park, a building complex that is also considered special in Europe. Environmental awareness, innovation, organic architectural elements with transparent huge glass surfaces, and a way of thinking in which visual culture also plays a prominent role. One of the biggest challenges in the Költő Kert villa park was the special solutions that the KAV staff had to create at the junction of the raw concrete surface and the glass membrane. Károly Lovász highlighted in the report that KAV's engineers and employees had to solve many challenges during the planning and execution, whether it was thermal technology, sun protection, mechanical engineering, glass railing connections or waterproofing. The result is a simultaneously organic and high-tech building, which is considered exceptional in Hungary not only in its appearance, but also in its innovations.
