Mould does not only damage the building construction and surfaces, but may cause serious health consequences for the occupants. Mould spores in indoor air are particularly dangerous for people with allergies and respiratory diseases. Children and older people are particularly sensitive to such influences.

What are the causes of mould growth?

Wrong ventilation and heating by the occupants

To save energy new buildings and renovated houses are tighter than a few decades ago. As a result, the building is no longer “automatically ventilated”, as it was in the past.

Moreover, today we produce more water vapour, by taking showers, washing or cooking. That means that you must ventilate more actively.

Correct ventilation means:

  • Fully open opposite windows several times a day for 5 to 10 minutes max.
  • Avoid permanently open or tilted windows

Otherwise your heating costs are going to explode.

Note: If possible, get a controlled ventilation system. It always provides the perfect air change.

Ventilation via controlled routes

Ventilation via controlled routes is essential. Here, the amount of ventilation is controlled. For example, make sure that you close the ventilation channels on really cold or hot days. The big advantage of ventilation via controlled channels is the fact that the channels can be cleaned in case of mould growth. This would not be possible if this has happened accidentally within the construction.

Save money (&time) by building air- & windtight

The costs of removing mould damage can quickly reach a five figure amount. Avoid this by

  • investing in high-quality products free from residential toxins
  • training your team on-site how to professionally apply the products
