The Stack Effect
Understanding Your Home’s Natural Airflow
Have you ever noticed that sometimes your home feels drafty and cool in the winter, and stuffy and hot in the summer? This phenomenon is known as the “stack effect.” This effect is a natural process that occurs in all homes and is the result of differences in indoor and outdoor air pressure. When indoor air is warmer than outdoor air, it rises and escapes through the upper parts of a building, creating negative pressure at the lower levels. This negative pressure pulls in outdoor air from any available gaps and cracks, leading to unwanted air infiltration.
What is the Stack Effect
To understand the stack effect, imagine a chimney. As the fire in the fireplace heats the air inside the chimney, it rises and escapes through the chimney top, pulling in cool outdoor air from the bottom. The same thing happens in your home. This effect can lead to energy loss and comfort problems, making it essential to reduce air infiltration.
The “stack” refers to the vertical movement of air within a building. As warm indoor air rises and escapes through the upper levels of a building, it creates a negative pressure at the lower levels, which pulls in cool outdoor air through gaps and cracks. This vertical movement of air is similar to the way air moves in a chimney or stack, hence the name “stack effect”.
As warm indoor air rises and escapes through the upper levels of your home, it pulls in cool outdoor air through gaps and cracks. This can lead to energy loss and comfort issues.
Proper air sealing and insulation can help to reduce air infiltration and the negative effects of the stack effect in a building, including those caused by electrical penetrations and drywall seams. By sealing gaps and holes in the attic, it is possible to improve the energy efficiency and comfort of your home.
Combat the Stack Effect with Air Sealing and Cellulose Insulation
Air sealing and cellulose insulation are two effective ways to reduce air infiltration and improve the performance of your home. Air sealing involves sealing all the cracks, gaps, and holes in your home that allow outdoor air to enter. This process involves identifying and sealing the sources of air infiltration, such as around windows, doors, electrical outlets, and ductwork.
Cellulose insulation, on the other hand, helps to slow down the stack effect by reducing the rate of air movement through walls and ceilings. Cellulose insulation is made of recycled newsprint and is known for its excellent air-sealing properties. When properly installed, cellulose insulation can significantly improve the energy efficiency of your home.
Say Goodbye to Energy Loss and Comfort Problems!
The stack effect is a natural process that can cause comfort problems and energy loss in your home. By air sealing and adding cellulose insulation, you can reduce air infiltration, improve the performance of your home, and keep your family comfortable all year round.
