Electrically opened rooflights and fa\u00e7ade windows let warm, humid air escape at the top while fresh air flows in at the bottom. This helps staff and goods without the running costs of fans.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>In brief:<\/strong> Linear or rack and pinion drives are suitable for continuous rooflights and rooflight domes, chain drives for fa\u00e7ade windows. Openings at the top and bottom create the stack effect. A controller with rain and wind sensor closes the windows when the weather changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which drive for which opening?<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Opening<\/th><th>Actuator<\/th><\/tr><\/thead><tbody><tr><td>Fa\u00e7ade window (bottom-hung or top-hung sash)<\/td><td>Chain actuator<\/td><\/tr><tr><td>Rooflight dome, roof hatch<\/td><td>Linear actuator<\/td><\/tr><tr><td>Continuous rooflight, shed window, long rows of flaps<\/td><td>Rack-and-pinion actuator<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can read more about retrofitting roof openings in the guide <a href=\"\/en\/retrofitting-skylights-drive-solutions-for-industrial-buildings\/\">Retrofitting rooflights in industrial halls<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to plan the ventilation<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Supply air at the bottom via fa\u00e7ade windows or doors, exhaust air at the top via rooflights.<\/li>\n\n\n<li>The greater the difference in height, the stronger the air exchange.<\/li>\n\n\n<li>Group several drives on one controller and switch them by push button, building automation schedule or sensor.<\/li>\n\n\n<li>For smoke ventilation requirements: an approved smoke control panel is required.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How many drives do I need for a continuous rooflight?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It depends on the length, weight and snow load of the flaps. Long flaps often need two synchronised drives. Send us the dimensions and we will calculate it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I retrofit existing rooflights?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In many cases yes. What matters are weight, opening width and a solid fixing point for drive and bracket.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an assessment, use the <a href=\"\/en\/project-enquiry\/\">Project enquiry<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Ventilating a warehouse naturally: how rooflights and fa\u00e7ade windows open with chain, linear or rack and pinion drives, creating cross ventilation and removing summer heat.<\/p>","protected":false},"author":9,"featured_media":0,"comment_status":"open","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1958],"tags":[],"class_list":["post-17858","post","type-post","status-publish","format-standard","hentry","category-lueftung-gebaeudeautomation"],"acf":[],"_links":{"self":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/posts\/17858","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/comments?post=17858"}],"version-history":[{"count":0,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/posts\/17858\/revisions"}],"wp:attachment":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/media?parent=17858"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/categories?post=17858"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/tags?post=17858"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
