URSACHEN UND AUSWIRKUNGEN VON SCHIMMELPILZSCHÄDEN IN DACHKONSTRUKTIONEN

About the Problem

Building is humanity's struggle against water, and mold damage is not the actual problem but merely the result of it. These two sentences are important in the interdisciplinary consideration of microbial contamination in indoor spaces and on roof structures.

Current Context

According to various sources from the Federal Ministry of Health, the Federal Environment Agency, environmental medical and toxicological institutes, as well as health insurance companies, formaldehyde and wood preservatives are no longer the most dangerous indoor allergens—rather, it is mold and its mycotoxins.

Causes

• Record construction times and increasingly airtight building envelopes
• Incorrect ventilation behavior
• Sealed building materials
• Errors in building physics
• Residual construction moisture during building erection

Roof Construction Context

In cases of mold damage to roof structures, roof craftsmen are often blamed. However, the causes of microbial infestation are frequently entirely different.
