In the face of increasing customer expectations, modern window joinery must meet a number of requirements that go beyond the basic function of providing light and protection from the elements. Today’s window joinery market focuses on thermal performance, soundproofing, energy efficiency, as well as visual aspects and ergonomics of use.
Thermal performance and energy efficiency
In today’s world, where sustainable construction and energy efficiency are becoming increasingly important, the thermal performance of windows is becoming of paramount importance. A key indicator that both customers and window manufacturers pay attention to is the heat transfer coefficient (Uw). This parameter determines the amount of heat which “escapes through the window”. – the lower its value, the better the thermal insulation. Modern aluminium and PVC windows, offered by companies such as Fintecnic, achieve Uw values as low as 0.8 W/(m²K), which is a significant achievement in terms of thermal insulation.
However, the energy efficiency of windows is not limited to the Uw coefficient alone. It is also worth paying attention to the G-factor, which determines the transmission of solar energy through the glass. An optimal G-factor maximises the use of natural sunlight, reducing the need for artificial lighting and heating, which translates into lower building operating costs.
Another also important parameter is the L-factor, relating to the air-tightness of the window. A high airtightness minimises uncontrolled airflow, which is key to maintaining a stable internal temperature and reducing energy losses.
In terms of energy efficiency, the use of appropriate glass technologies is also important. In this respect, two- or three-chamber glazing filled with noble gas (e.g. argon) is invaluable in significantly improving the thermal insulation of windows. Furthermore, the use of appropriate low emissivity coatings on the glazing can further increase its efficiency by reflecting heat into the room in winter and blocking excessive heat flow in summer.
Soundproofing
The soundproofing of windows is a parameter that is becoming increasingly important, especially in the context of increasing urbanisation and increased noise levels in urban environments. The Rw coefficient, which determines the sound insulation of windows, has become a key criterion for customers seeking peace and comfort in their homes and workplaces. The high-performance windows that Fintecnic offers achieve an Rw factor of 49 – 52, which effectively dampens external noise, creating quiet and peaceful interiors.
Guaranteeing high soundproof windows requires advanced technologies and materials. A key element is multi-layer glazing, which, thanks to the varying thickness of the glass and the air space between them, effectively dampens sound and further improves sound insulation.
Another important aspect in terms of soundproofing is the proper sealing of windows. Modern sealing systems, both in the window frames and at the installation points, play a key role in preventing noise transmission. The seals must be durable and resistant to changes in temperature and humidity in order to retain their insulating properties over the long term.
The design of the window frame also has a significant impact on soundproofing. Aluminium or PVC profiles, used by Fintecnic, are designed to minimise sound transmission. In the case of aluminium windows, the use of additional thermal breaks can also help to improve sound insulation.
The aspect of window installation is also worth noting. Professional installation, in accordance with the rules of the art of construction, is essential to achieve optimum soundproofing. Improperly installed windows can significantly reduce their acoustic effectiveness, even if the windows themselves are of high quality.
Visual aspects and ergonomics
In the field of modern window joinery, visual aspects and ergonomics play as important a role as technical performance. Customers expect windows to be not only functional but also aesthetically pleasing to the architecture of the building. Fintecnic, responding to these needs, offers a wide range of finishes and colours, allowing customers to choose windows that perfectly match their living space and aesthetic preferences.
Innovative solutions, such as sliding windows, are increasingly chosen for their space-saving ability and ease of use. Large glazing, which maximises the use of natural light, is not only a design trend, but also has a practical function, creating a seamless transition between the interior and exterior spaces.
Window joinery of the highest quality
Modern window joinery has to meet complex and diverse customer expectations. From high energy efficiency, to excellent soundproofing, to aesthetic and ergonomic solutions – every aspect is crucial. At Fintecnic, we are constantly refining and adapting our products to meet increasing demands, while providing products that are durable, functional and aesthetically pleasing to contemporary architectural trends.
