Danger of fungus formation
Storyboard 
The delay in installing the roof caused the mezzanine floor to get wet, creating a risk of mold development and deterioration of the affected SIP panels. Therefore, it is crucial to dry and continuously monitor the situation to determine if additional measures are needed.

Optimal conditions for fungal growth
Description 
To prevent the issue of the wet SIP panels in the mezzanine from becoming complicated by mold growth, it is important to be aware of the optimal conditions for mold growth:
Temperature
• Optimal Range: 25°C to 30°C (77°F to 86°F)
• Mold can grow in a broader range from 15°C to 32°C (59°F to 90°F), but it thrives best in warmer, more humid conditions within the optimal range.
Humidity
• Optimal Humidity: Above 70% relative humidity (RH)
• Mold growth can begin at humidity levels as low as 60% RH, but it becomes much more vigorous and rapid when the humidity exceeds 70%.
Other Contributing Factors
• Moisture Content in Wood: Wood with a moisture content above 20% is highly susceptible to mold growth.
• Air Circulation: Poor ventilation can trap moisture, creating an environment conducive to mold growth.
• Light: Mold tends to grow more easily in dark or dimly lit conditions.
• Surface Cleanliness: Dirty or dusty surfaces can provide additional nutrients for mold growth.
Prevention Tips
• Maintain Low Humidity: Keep indoor humidity levels below 60% using dehumidifiers or air conditioning.
• Ensure Good Ventilation: Proper airflow helps to reduce humidity and dry out any moisture.
• Regular Inspections: Check for leaks, water damage, and areas where condensation might occur.
• Clean and Dry: Regularly clean surfaces and ensure they are dry, especially in basements, bathrooms, and kitchens.
