House Pressure Driving Forces

It's important to understand the driving forces that cause air to flow inside and outside your house.

The driving force is created by air pressure differences between the inside of the house and the outside. The air pressure differences cause air to flow through the house, which causes greater discomfort as more cold air leaks into the house.

Stack Effect

Stack effect happens when the air inside your house is warmer than the air outside.

Wind Effect

When the wind is blowing, it can affect the air flow in your home.

Exhaust Effect

The exhaust effect occurs when an exhausting appliance is operating.
