In simple terms, a thermally broken frame features an insulated barrier between the interior and exterior aluminum profiles. Because aluminum is a highly conductive metal, standard frames easily transfer heat and cold into your building. A thermal break incorporates a low-conductive material (such as high-strength Polyamide 66 reinforced with glass fiber) that mechanically interrupts this thermal bridge.
This advanced engineering ensures that exterior temperatures do not transfer indoors: it seals the warmth inside during winter and keeps the scorching heat outside during summer. Specifying thermally broken windows and doors dramatically enhances your building’s thermal insulation, meets strict local energy codes (like NCC Section J), and slashes monthly HVAC energy costs.
