AIRLEMENTS<\/span><\/h1>\n

Insulated Walls with Sustainable Mineral Foam<\/h4>\n

The Airlements project, developed by researchers at ETH Zurich in partnership with FenX AG, uses large-scale robotic 3D printing to create monolithic, lightweight, insulated wall systems from cement-free mineral foam made from recycled waste. With varying densities, this innovative material optimises thermal performance and energy efficiency, reducing operational energy needs for heating. The Airlements prototype demonstrates rapid, low-energy 3D printing, with each 25 kg hollow segment hardening over a week without energy-intensive processes. The technology\u2019s versatility enables non-structural exterior walls and seamless integration of reinforcements.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image media=”94579″ media_width_percent=”100″ uncode_shortcode_id=”207860″][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ back_color=”color-gyho” overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ content_parallax=”0″ uncode_shortcode_id=”192115″ back_color_type=”uncode-palette”][vc_column width=”1\/1″][vc_single_image media=”94578″ caption=”yes” media_width_percent=”65″ media_ratio=”four-three” alignment=”center” lbox_caption=”yes” uncode_shortcode_id=”192869″][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ content_parallax=”0″ uncode_shortcode_id=”284875″][vc_column width=”1\/3″][vc_single_image media=”94582″ media_width_percent=”50″ alignment=”right” uncode_shortcode_id=”569668″][\/vc_column][vc_column width=”1\/3″][vc_single_image media=”94583″ media_width_percent=”50″ alignment=”center” uncode_shortcode_id=”193694″][\/vc_column][vc_column width=”1\/3″][vc_single_image media=”94581″ media_width_percent=”50″ uncode_shortcode_id=”144531″][\/vc_column][\/vc_row]<\/p>\n<\/div><\/span>","protected":false},"excerpt":{"rendered":"
