Aluminum is a metal with high thermal conductivity by nature. However, modern engineering solutions transform this characteristic into an advantage by completely severing the thermal bridges between the exterior and interior environments using thermal break technology. By integrating polyamide-based barriers into the profile cross-sections, Sistem Aluminum develops high-performance joinery systems that bring thermal transmittance coefficients (U-values) close to passive house standards.
In the current era, Sistem Aluminum provides a holistic insulation strategy rather than just manufacturing profiles. The designed insulated series profiles prevent indoor heat from escaping in winter and block outdoor heat from entering in summer, reducing the load on HVAC systems by up to 40%. This energy saving is the most critical technical move toward minimizing the carbon footprint of buildings throughout their life cycle.
Polyamide Barrier Technology and Thermal Break
Polyamide barriers, the heart of thermally insulated aluminum systems, mechanically separate the inner and outer aluminum profiles while ensuring they function as a structural whole. The barrier assembly processes carried out in Sistem Aluminum‘s production lines are performed with millimetric precision, guaranteeing the profile’s resistance to torsion and bending. The compatibility of polyamide’s thermal expansion coefficient with aluminum allows the system to maintain its air and water tightness performance even under extreme temperature fluctuations.
To take insulation performance to the next level, multi-chamber barrier designs and EPDM gasket systems are utilized to minimize air circulation within the profile. This multi-layered insulation strategy not only prevents heat loss but also provides high acoustic insulation, creating an effective shield against noise pollution in urban areas.
Glass Integration and Advantages of Wide Glazing Cavities
Total thermal performance in insulated aluminum joinery is a result of the combination of the profile and the glass (Uw ). Sistem Aluminum‘s modern joinery series offer wide glazing cavities and deep mounting depths that allow for the use of triple glazing. This design flexibility ensures the selection of the most ideal Insulating Glass Unit (IGU) according to the project’s climate zone.
The expansion of thermal barriers and the use of special insulating foams placed inside the profiles interrupt the heat flow at the center of the profile, completely eliminating the risk of condensation. Preferred in today’s prestigious projects, these systems maximize user comfort by keeping surface temperatures close to room temperature, even on large glass surfaces. Especially in glass-fronted buildings, this thermal stability provided by Sistem Aluminum is a factor that directly improves the Energy Performance Certificate rating.
Sustainable Architecture and Green Building Certifications
In green building certification systems such as LEED and BREEAM, the energy performance of the building envelope is the category with the highest point weight. Sistem Aluminum contributes to these certification processes in two ways: through low-carbon production processes and “Green Aluminum” profiles with high recycling rates. While documenting sustainability in production, it simultaneously lowers the building’s operational energy demand through the high thermal insulation it provides.
Combining the aesthetic power of aluminum with advanced thermal barrier technologies, Sistem Aluminum offers a vision that ends energy waste in modern urban planning. The architecture of the future will be built upon these insulated systems, where engineering meets elegance and environmental sensitivity.
