The architecture industry is entering a new phase in 2025, where the need for more modern, neat, and functional designs is increasing. At this stage, many architects are turning to modern casement systems to achieve the ideal combination of aesthetics and performance.
Modern casement systems are now considered more flexible in facade design, especially for buildings with minimalist or contemporary lines. FENSTELA presents casement technology designed to meet the needs of this year’s architectural projects—from residential homes and luxury villas to commercial buildings.


The modern FENSTELA casement system is designed with a more precise structure, providing maximum soundproofing and airtightness. This is essential for architects to create more comfortable spaces, especially in urban environments.
FENSTELA casement windows can be opened sideways or upwards, providing design flexibility without compromising security or air circulation. This flexibility is one of the main reasons architects are choosing modern casement systems for their 2025 projects.
With luxury aluminum material, FENSTELA casement products are more resistant to corrosion, extreme weather, and temperature changes. Architects also don’t need to worry about long-term maintenance, which is usually a concern in large-scale projects.
The 2025 architectural trend emphasizes clean lines, color harmony, and understated elements. Modern casement systems have neat and proportional frames that support a more modern-looking facade. FENSTELA also provides color options such as deep grey sandy, black matte, and white PVC to suit the style of the building.


The hinge system on FENSTELA casement windows is designed to be strong, resistant to sagging, and highly secure, making it suitable for both residential and commercial projects.
The use of luxury aluminum gives FENSTELA casement windows an exclusive look and robust structural performance. Architects can create a luxurious impression without compromising strength.
FENSTELA understands that every project has its own unique characteristics. Casement systems can be customized according to the size, opening direction, and color required by the architect.


Architects are switching to modern casement systems not just because it is a trend, but because these systems offer greater efficiency, aesthetics, and performance compared to traditional systems. With advantages in soundproofing, flexible opening directions, material durability, and an elegant appearance, FENSTELA makes casement windows the ideal solution for 2025 projects.
