Goodbye to Mildew in Interior Spaces

Mould and its Origins

The Problem of Mould in Interior Spaces

Infestation with mould and mildew is one of the most common “environmental” problems in interior spaces. The reason mould grows is usually a higher moisture content in the respective building material or on its surface. Along with “wet” walls due to insufficient protection against driving rain or rising damp, the cause is often due to the insufficient thermal insulation standard found in old buildings, particularly when the air exchange rate has been reduced because of changes made to the building. 

New window are often installed without improving the insulation of exterior walls or taking into account that ventilation requirements are higher. Without sufficient ventilation, humidity on the surface of the walls rises, making it possible for mould to grow. Condensation doesn’t even need to form. For most types of mould and mildew, 70% humidity is perfectly sufficient for growth.

The following conditions and factors are usually found when mould/mildew infests living spaces: 

  • Too much moisture is given off into the air of the room
  • Airing is not executed properly or the capacity for airing is insufficient
  • Insufficient heating
  • Poor standard of heat insulation/heat bridges
  • Furnishings have been put in the wrong place
  • New windows have been installed when old buildings are restored.
  • There is moisture in the structure, e.g. through insufficient protection of the facade against driving rain, missing or defective waterproofing, leaky roofs, dampness in new buildings, damage caused by water.
