ETFE transmits a high proportion of daylight, is lightweight and can be printed for shading. Multi-layer cushions improve insulation.<\/p>\n<h3>How is condensation handled?<\/h3>\n<p>Through ventilation, roof slope and drainage details that lead condensation to a gutter. The inner surface should not drip onto plants.<\/p>\n<h3>How long do ETFE cushions last?<\/h3>\n<p>Typically 20\u201330 years, depending on film grade, UV exposure and maintenance. Individual cushions can be replaced.<\/p>\n<h2>Hablar sobre un proyecto similar<\/h2>\n<p>Send the growing requirements, site climate and plan dimensions.
