Thermal Break System Solutions for Aluminum Windows & Doors

A thermal break system is an engineered assembly designed to prevent thermal energy transfer between conductive materials, primarily in building envelopes and industrial applications. These systems are fundamental to modern energy-efficient design, addressing the critical issue of thermal bridging where heat flows readily through more conductive components like aluminum or steel frames, leading to significant energy loss, condensation, internal comfort issues, and potential mold growth. The core of such a system is the thermal barrier itself, often a high-performance polymer strip like PA66 GF25 or PA66 GF30, which is mechanically inserted and sometimes bonded within a metal profile. This creates a continuous line of insulation with low thermal conductivity, dramatically reducing the overall U-value and Psi-value of the assembly. The design integrates considerations for structural integrity, as the system must withstand wind loads, building movements, and in the case of structural thermal breaks, considerable shear and compressive forces. Performance is validated through standardized testing, including thermal simulations and physical tests per standards like EN 14024, which classifies performance. Beyond energy savings, these systems enhance occupant comfort by maintaining warmer interior surface temperatures in winter and cooler ones in summer. They are indispensable in achieving stringent building codes and sustainability certifications such as Passive House, LEED, and BREEAM. The application extends beyond windows and doors to include balcony connections, parapets, and curtain walling, making them a holistic solution for improving a building's thermal envelope, reducing its carbon footprint, and ensuring long-term durability and occupant well-being.
