A polyamide strip separates the inner and outer frames so heat cannot travel straight through the metal. This article explains why they matter for importers.<\/p>\n<h2>Why Plain Aluminum Loses Heat<\/h2>\n<p>Aluminum conducts heat ~1000x faster than wood. A single-frame window becomes a thermal bridge: warm indoor air meets cold metal, drops in temperature, and condenses. Energy leaks and windows sweat.<\/p>\n<h2>How the Thermal Break Works<\/h2>\n<p>A non-conductive polyamide (PA66GF25) bar is inserted between the exterior and interior profiles. It mechanically joins the frame while electrically isolating the two sides, cutting conduction by 40\u201360%.<\/p>\n<h2>Measurable Benefits<\/h2>\n<ul>\n<li><strong>Lower energy bills<\/strong> \u2013 Less heating\/cooling loss through the envelope.<\/li>\n<li><strong>No condensate<\/strong> \u2013 Interior surface stays above dew point.<\/li>\n<li><strong>Comfort<\/strong> \u2013 No cold drafts near windows.<\/li>\n<li><strong>Code compliance<\/strong> \u2013 Meets passive-house and strict-climate standards.<\/li>\n<\/ul>\n<h2>Specifying for Export<\/h2>\n<p>Request U-value (W\/m\u00b2K) and confirm the break width (typically 14\u201334&nbsp;mm). Pair with double or triple glazing and warm-edge spacers for best results.
