Maintaining Proper Humidity in Winter

Impact on the Building Envelope

As winter settles in, homeowners focus on keeping their living spaces warm and cozy. In the quest for comfort, one aspect often underestimated is humidity control. Proper humidity levels within your home, typically ranging from 20-30%, are essential for several reasons. Neglecting humidity can not only affect your comfort but also have a significant impact on the building envelope. Excess humidity in your home during winter can lead to various issues, particularly within the building envelope. The building envelope includes all the components that separate your living space from the outdoor environment, such as walls, windows, doors, and the roof. When humidity levels are too high, it can result in the following adverse effects: 

1. Condensation: Excess moisture in the air can condense on cold surfaces within the building envelope, leading to water damage and potential mold growth. This can compromise the structural integrity of your home. 

2. Reduced Insulation Effectiveness: High indoor humidity can negatively impact the insulation within the walls and roof. Damp insulation becomes less efficient at retaining heat, leading to increased heating costs. 

3. Material Degradation: Building materials, such as drywall and wooden structures, can deteriorate over time when exposed to excessive moisture. This can lead to costly repairs and maintenance. 

To prevent these issues, homeowners should invest in humidity control measures like dehumidifiers and proper ventilation systems. Heat recovery ventilation (HRV) systems are an excellent addition to homes in colder climates. These systems help maintain indoor air quality while efficiently exchanging stale, moist air with fresh, dry outdoor air. HRVs recover heat from the outgoing air

By maintaining the right indoor humidity levels with the help of HRVs, you can ensure your building envelope remains in good condition, contributing to a comfortable and structurally sound home during the winter months.
