Learn when to avoid vapour barriers to prevent moisture issues and ensure healthy indoor air quality.
8 views
Avoid using vapour barriers in humid climates where walls need to breathe, such as in homes without air conditioning. They can trap moisture, leading to mold and rot. In old buildings with traditional masonry, vapour barriers can harm structural integrity by restricting natural moisture regulation. Instead, consider using vapor-permeable materials or expert consultation. Proper ventilation and insulation are essential factors for ensuring healthy indoor air quality and building longevity without vapour barriers in these scenarios.
