Moisture Control Techniques
Mould growth thrives in damp, humid environments. Effective moisture control is, therefore, a critical component of any mould mitigation strategy. Let’s explore some key techniques for managing indoor humidity and preventing water intrusion.
Ventilation and Dehumidification
Proper ventilation is essential for removing excess moisture from the indoor environment. Exhaust fans in bathrooms, kitchens, and other high-moisture areas can help expel warm, humid air to the outside. Supplementing the HVAC system with whole-home dehumidifiers or standalone dehumidifiers can further reduce indoor humidity levels, creating a less favourable environment for mould growth.
Insulation and Vapour Barriers
Ensuring the building envelope is properly insulated and sealed can prevent moisture from penetrating the structure. Insulation in walls, attics, and crawl spaces helps maintain temperature differentials and reduces the risk of condensation. Vapour barriers, such as polyethylene sheeting or specialized membranes, act as a barrier to moisture migration, blocking water vapour from entering the building materials.
Drainage and Waterproofing
Effective drainage systems, both interior and exterior, are crucial for directing water away from the building’s foundation and preventing water intrusion. Proper grading, downspout extensions, and perimeter drainage help mitigate the risk of flooding, leaks, and moisture buildup around the building’s perimeter.
Additionally, waterproofing techniques, such as the application of sealants, coatings, or membranes, can protect the building envelope from water infiltration through the roof, walls, and foundation. These measures help maintain a dry, mould-resistant indoor environment.
Enhancing Energy Efficiency
Energy-efficient HVAC systems not only reduce operating costs but also contribute to improved indoor air quality and mould prevention. Let’s explore some of the key strategies for enhancing HVAC energy efficiency.
