Expertenleitfaden 2025 f\u00fcr den Bau<\/h3>\n<p>Wenn Sie sich jemals gefragt haben, warum Sandwichpaneele verblassen, sind Sie nicht allein. Viele Auftragnehmer, Architekten und Hausbesitzer bemerken matte oder kreideartige Oberfl\u00e4chen nur wenige Jahre nach der Installation. Die Wahrheit ist\u2014Verblassen ist nicht nur ein kosmetisches Problem.

Mit der Zeit oxidieren diese Pigmente und die Oberfl\u00e4che verliert Glanz und Helligkeit. Deshalb verblassen Sandwichdachpaneele oft schon nach wenigen hei\u00dfen Jahreszeiten.<\/p>\n<p>Dunklere Paneele absorbieren mehr W\u00e4rme, was bedeutet, dass dunkle Farb-Sandwichpaneele schneller verblassen als hellere T\u00f6ne. In Labortests erreichten schwarze Paneele bis zu 25 \u00b0C mehr Hitze als wei\u00dfe.<\/p>\n<p class=\"eeat\">\u201cUV-Belastung \u00fcber 180 MJ\/m\u00b2 pro Jahr kann den Glanzgehalt bei Polyesterbeschichtungen halbieren.\u201d \u2014 Geb\u00e4udeh\u00fcllungsingenieurwesen, Elsevier, 2024<\/p>\n<p>F\u00fcr Projekte unter starker Sonneneinstrahlung erhalten UV-best\u00e4ndige Beschichtungen wie PVDF oder Fluorkunststofffarbe die Farbintensit\u00e4t 15\u201320 Jahre lang, selbst in tropischen oder W\u00fcstenklimazonen.<\/p>\n\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/shanghepanel.com\/wp-content\/uploads\/2025\/11\/DM_20250707170235_009.jpeg\" alt=\"warum verblassen Sandwichpaneele\" class=\"wp-image-6886\" srcset=\"https:\/\/shanghepanel.com\/wp-content\/uploads\/2025\/11\/DM_20250707170235_009.jpeg 640w, https:\/\/shanghepanel.com\/wp-content\/uploads\/2025\/11\/DM_20250707170235_009-300x225.jpeg 300w, https:\/\/shanghepanel.com\/wp-content\/uploads\/2025\/11\/DM_20250707170235_009-16x12.jpeg 16w, https:\/\/shanghepanel.com\/wp-content\/uploads\/2025\/11\/DM_20250707170235_009-600x450.jpeg 600w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><figcaption class=\"wp-element-caption\">warum verblassen Sandwichpaneele\n<\/figcaption><\/figure>\n\n\n\n<h3>Wetter, Klima &amp; Regionale Belastung<\/h3>\n<p>Ein weiterer Hauptgrund f\u00fcr das Verblassen von Sandwichpaneelen in tropischen Klimazonen ist Feuchtigkeit und Salz.
