When temperatures soar in the Quad Cities, your first instinct might be to throw open every window and door. But here’s the shocking truth: you’re actually making your home hotter.
Summer in eastern Iowa and western Illinois can be extremely hot and humid. One day you’re enjoying perfect weather for a barbecue along the Mississippi River, and the next day you’re sweating through another scorching heat wave. We’ve all been there…desperately opening windows, hoping for a cool breeze that never comes.
But what if we told you there’s a better way? A method so simple, yet so effective, that it’s been keeping people cool for thousands of years.
The Cave Method: Ancient Wisdom for Modern Heat
Door and window expert Joseph Holman has a game-changing approach. He calls it thinking of your home “like a cave.”
Here’s how it works: caves stay cool during heat waves because they’re dark and don’t allow hot air to flow through them. Your home can work the same way.
Instead of opening windows and doors, do the opposite. Keep everything closed when it’s hot outside. This keeps the warm air where it belongs, outside your home.
“You want to reduce sunlight and stop the movement of outside air inside,” Holman explains. “Even switching off the lights will help.”
Think about it this way: if you had air conditioning running, you wouldn’t open your windows because you’d be wasting cool air. The same logic applies in reverse. When you open windows during a heat wave, you’re letting hot air pour into your home.
Why This Works in the Quad Cities
Our area faces unique challenges during the summer heat. The humidity from the Mississippi River can make temperatures feel even hotter. Additionally, the large windows in many Quad Cities homes can become heat magnets when the sun is beating down.
Even if you think a shaded area of your house will bring in cooler air, you’re still inviting hot air inside. The temperature difference is just not enough to make it worthwhile.
Long-Term Solutions for Quad Cities Homes
The cave method works great for immediate relief, but you can also make changes that will keep your home cooler all summer long:
Window Improvements: Tinted film on windows reflects heat before it enters the home. Modern glass also has better heat-blocking qualities than older windows.
Smart Blinds: Integral blinds can be installed without changing your whole window. They last longer than outdoor blinds and won’t get damaged by our Iowa and Illinois storms.
Shade Solutions: Roller blind canopies keep direct sunlight away from your doors and windows.
