Airtight constructions have advantages and disadvantages. In order to prevent costly energy losses, enormous progress has been made in the thermal insulation and airtightness of external walls and windows over the last 10 years. However, increasingly airtight constructions are keeping not only heat, but also harmful pollutants inside.
The replacement of internal air with external air (the air exchange rate) is now often ten times lower than in old buildings. Modern airtight building envelopes now place much higher demands on building materials than before. Exhaustive airing or controlled domestic ventilation should keep the concentration of harmful substances low. However, the safest option is not to let harmful substances into the building in the first place.
Like egg shells Baumit Klima products contain lime. Egg shells provide protection for the chick, act as a climate chamber and can even be used as food. Too much humidity in the air increases the risk of mould.
Mould and fungi are probably among the most feared risks to health at home. Lime is alkaline. This naturally prevents mould from forming.
