The Science Behind Attic Airflow and Energy Savings
Living in Chehalis, WA , you understand the importance of keeping your home cool year-round. Effective cooling systems play a crucial role in indoor air quality, especially in our local climate conditions .
These systems work by facilitating air movement that expels heated air from your attic space. When temperatures rise, roof spaces can exceed extreme temperatures , which makes your air conditioning to operate less efficiently .
The fundamental principle of attic ventilation involves creating a continuous airflow system that removes hot air from your attic space while drawing in cooler outside air. This process, known as the stack effect, occurs naturally when intake vents (typically located in soffits) allow cool air to enter while exhaust vents (like attic fans or ridge vents) remove heated air. For 98532 residents, this system is particularly important due to our regional climate patterns and seasonal temperature variations.
