What does proper sealing of windows and doors contribute to?

Proper sealing of windows and doors is crucial for creating a barrier against environmental factors, primarily reducing the entry of moisture into a building. When windows and doors are adequately sealed, they prevent water from infiltrating through cracks and gaps. This is particularly important in regions with high humidity or precipitation, as excess moisture can lead to various issues, including mold growth, structural damage, and decreased indoor air quality.

Effective sealing not only protects the interior environment from external moisture but also helps maintain a controlled indoor climate, making it more comfortable for occupants. The reduction of moisture entry directly correlates with the longevity and health of the building materials and overall building integrity.

In contrast, better decoration, improved outdoor views, and enhanced ventilation are outcomes that do not directly relate to the primary purpose of sealing. While they may have aesthetic or airflow benefits, they do not address the moisture control aspect, which is the key focus of the question.
