What is Stack Effect?

Stack Effect and Home Humidity

The stack effect is the movement of warm, dry air rising and escaping through the upper levels of the home and cooler, wet air finding its way into the lower levels in order for the home to equalize.

Excess moisture in crawl spaces and basements often migrates to the upper levels of the home through the stack effect. In essence, whatever air is below the house is also inside the house.

STACK EFFECT CONTRIBUTES TO:

• High humidity
• Pest infestations
• Mold growth
• Musty odors
• Damage to property
• Poor indoor air quality
