OPTIMISED CROSS-PLATFORM ANALYTICS

Why is an Airtightness Test Important?

1. ✓Increase energy efficiency: Air leaks cause heat loss and raise heating costs.
   

2. ✓Prevent structural damage: Uncontrolled airflows can introduce moisture into the structure, promoting mould growth.
   

3. ✓Enhance indoor comfort: Reduces draughts and temperature fluctuations.
   

4. ✓Ensure compliance with standards: Required for KfW and Passive House certification as well as compliance with DIN 4108-7 and EnEV/GEG regulations.
