Intelligent, effective solutions for joints (1/8) – typical leaks: cable feed-throughs for electrical installations

Properly installed air sealing is the basis for energy-efficient buildings that are protected against damage to structures. 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.

This series of articles summarises typical, challenging joint situations and shows how technicians can find practical solutions for these challenges. It also provides an overview of the detail features for which prefabricated solutions are available that allow tradespeople to achieve airtightness in a quick, easy and reliable manner.
