In addition, planners and tradespeople are liable for any damage that may occur later in the case of flawed planning and installation. Blower door tests during the construction phase and after completion show whether the values demanded by regulations and standards (German Energy Saving Ordinance, DIN standards) are achieved in practice. These tests also show where leaks are present in the building envelope.<\/p>\n\n\n\n<p class=\"has-background has-light-gray-background-color\">This series of articles summarises typical, challenging joint situations and shows how technicians can find practical solutions for these challenges.

The cause of holes in the building envelope is often not just installation work carried out by tradespeople, but simply poor planning. Electricians, plumbers, carpenters and installation technicians for solar and ventilation systems are then confronted with situations that impact on a number of different trades that they cannot easily solve on site. Another possible scenario is that leaks occur later on \u2013 after the airtight layer has been completed and formally accepted \u2013 because a follow-on trade has installed pipes or cables, for example, and penetrated the airtight layer. In this case, these locations need to be sealed again, but this is often not done.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"684\" data-size=\"1092x729\" src=\"https:\/\/blog.proclima.com\/int\/files\/2020\/05\/korrekte-ausfuehrung-kabel-durchdringung-1024x684.jpg\" alt=\"\" class=\"wp-image-429\" srcset=\"https:\/\/blog.proclima.com\/int\/files\/2020\/05\/korrekte-ausfuehrung-kabel-durchdringung-1024x684.jpg 1024w, https:\/\/blog.proclima.com\/int\/files\/2020\/05\/korrekte-ausfuehrung-kabel-durchdringung-300x200.jpg 300w, https:\/\/blog.proclima.com\/int\/files\/2020\/05\/korrekte-ausfuehrung-kabel-durchdringung-768x513.jpg 768w, https:\/\/blog.proclima.com\/int\/files\/2020\/05\/korrekte-ausfuehrung-kabel-durchdringung-449x300.jpg 449w, https:\/\/blog.proclima.com\/int\/files\/2020\/05\/korrekte-ausfuehrung-kabel-durchdringung.jpg 1092w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Solution for cable feed-throughs: the <a href=\"https:\/\/proclima.com\/products\/bonding-agents\/grommets-cables\">grommet <\/a>fits snugly around the cables and is then stuck to the subsurface.<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-group has-light-gray-background-color has-background\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\"><strong>This Series was wirtten by Jens L\u00fcder Herms and Holger Merkel<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-media-text alignwide\" style=\"grid-template-columns:22% auto\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" src=\"https:\/\/blog.proclima.com\/de\/files\/2020\/04\/Jens-Lueder-Herms.jpg\" alt=\"Jens L\u00fcder Herms, Zimmerer &amp; Diplom-Ingenieur (FH), Exportmanager und Anwendungstechniker\" class=\"wp-image-8539\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p>Jens L\u00fcder Herms, carpenter and graduate engineer, Export Manager and Application Technology specialist, pro clima Research and Development,, <a href=\"\/\/www.proclima.de\">www.proclima.de<\/a>.
