to direct either north or south light. However, retro systems are preferably installed horizontally valley. In the roof area, the retro systems are integrated as a fixed inlet in the cavity of insulating glass. Depending on the pitch of the roof, internal retro systems are also available that can be blinded or rotated.   <\/p>\n<p>The illustrations show the options for light control and shading in flat roofs and north and south-facing sheds. Which system is used, is determined by the use of the interior space. In museum or sports buildings,<br>direct light ingress from the south is generally prevented. The interior is illuminated exclusively by daylight from the northern sky. In passive solar architecture, the flat southern sun is used and only the high summer sun is blocked out.    <\/p><\/div><\/div><\/div><\/div><\/div><div id=\"panel-e720-e30\" class=\"x-tabs-panel e720-e30\" role=\"tabpanel\" aria-labelledby=\"tab-e720-e30\" aria-hidden=\"true\" data-x-toggleable=\"tab-item-e720-e30\"><div class=\"x-div e720-e31 mk0-1m mk0-1n mk0-1o mk0-1p mk0-1y\"><div class=\"x-text x-text-headline e720-e32 mk0-1b mk0-1e mk0-1f mk0-1g mk0-1h mk0-1i\"><div class=\"x-text-content\"><div class=\"x-text-content-text\"><span class=\"x-text-content-text-primary\">RETRO<i>Flex<\/i> in flat roofs<\/span>\n<\/div><\/div><\/div><span class=\"x-image e720-e33 mk0-3j mk0-3k mk0-3l\"><img decoding=\"async\" src=\"https:\/\/www.retrosolar.de\/wp-content\/uploads\/2025\/07\/RETROFlex-im-Flachdach-2.webp\" width=\"1126\" height=\"551\" alt=\"Image\" loading=\"lazy\"><\/span><div class=\"x-text x-content e720-e34 mk0-31 mk0-32 mk0-33 mk0-34 mk0-35 mk0-36 mk0-39\"><p>Micro-structured slats in an upright position deflect the overheating sun from the south and allow the zenith and light from the northern sky to flood in.
