If the stack effect is at work in your home, it’s losing energy,
and worse, you probably aren’t even aware of it. With the stack
effect, air moves into and out of the house via chimneys, stacks, and
other entry points. This phenomenon results from a variation in indoor
and outdoor air density caused by temperature differences. As the change
in the indoor and outdoor temps become more dramatic, the stack effect
gets worse. The end result is that air leaks can jeopardize your home’s
energy efficiency, causing your utility bills to skyrocket. Del-Air, leaders in
AC service, explain.
Understanding the Stack Effect
In order to appreciate the danger of air leaks, you need to understand
how the stack effect works. In winter, the cold air outside has higher
pressure and density than inside the home. As a result, the air moves
into the home at lower levels through cracks, gaps, and leaks. In summer,
the reverse happens, due to the same pressure principles acting in reverse.
The good news is that stopping the effects of this problem is relatively
easy. All you need to do is seal the air leaks in your home, and you’ll
experience lower energy bills as well as a more comfortable living space.
Where to Seal Air Leaks
Work your way from the top of the house (attic) to the bottom (basement)
and seal any cracks you find with caulk. You should use expanding foam
spray for larger cracks and gaps. Additionally, you should pay attention
to recessed lights, as they offer a direct path for hot or cold air to
escape, and also check the spaces around chimneys and flues.
