While you may lock up your house and rely on your HVAC system for comfort during the hot summer months, the centuries-old European ritual is now trending and changing how we think about indoor climate control. The practice of “house burping,” known in Germany as Luften — which means “air out” — is a window trick that more people are trying.
Opening your windows during the cooler evening hours creates an escape hatch for indoor heat to escape from your home, reducing your cooling bills and simultaneously refreshing your air quality. We spoke with a window expert from Pella about how burping works in your home, how to master the technique regardless of your window style, and how to maximize the efficiency of your home this summer.
What is house burping?
House burping is a loose term for what homeowners have done for generations: Open their windows to ventilate the house outsidesays Nicole Willits, manager of design trends and production and sustainability at That corporation. “While the phrase itself is trendy, the concept is not new. It is similar to Lufthansa’s European practice, where daily ventilation is part of routine home care.” It is common in Germany to open doors and windows for 10 to 30 minutes a day to remove stale indoor air, lower humidity and naturally cool their living space.
This is how houses are built today, especially in the United States. “Modern construction prioritizes energy efficiency and tight envelopes, but when a house is tightly sealed, air doesn’t naturally exchange the way it once did,” explains Willits. Deliberately opening windows lets fresh air in and helps move stale indoor air out. “While house burping may seem playful, it reflects a very practical idea, using windows to manage airflow and maintain a comfortable indoor environment,” notes Willits.
Benefits of House Burping
Willits says windows play a big role in keeping a home comfortable throughout the summer, giving homeowners control over airflow, light and how the space actually feels. “Opening it up for a while can also make a difference, as the fresh air helps flush out that stale, heavy feeling and can quickly improve overall comfort.” It also supports airflow and natural light, which most homeowners value in the warmer months.
Windows also help manage what happens inside the home on a daily basis. “Things like cooking and bathing add moisture to the air, and if it’s prolonged, it can lead to discomfort or condensation,” Willits explains. “Short bursts of ventilation — when the weather permits — help reset that balance.”
And it’s not just moisture. Everyday items such as cleaning products, candles and furniture can affect indoor air quality. He also recommends opening windows for a few minutes to help expel polluted air and bring in fresh outside air. “Used intentionally, especially during the cooler parts of the day, windows can help a home feel lighter and more comfortable without relying entirely on air conditioning.”
House burping with double-hung windows
Double-hung windows A popular modern style of window is often found in newer homes. It consists of two vertically arranged panels, both of which can move all the way up and down. If you’re looking for ventilation, double-hung windows are a better choice than single sash windows because they open from both the top and bottom of the frame. This window is a great choice for bathrooms and bedrooms.
To declutter your home with double-hung windows, open your windows for a few minutes each day to let in light and improve air quality and circulation throughout the home, says Willits. “On double-hung windows, this is done by opening the top or bottom sash (or both), which lets stale air out and fresh air in,” Willits explains.
How to Burp Your House If You Don’t Have Double-Hung Windows
Even if your home doesn’t have double-hung windows, you can still benefit from house burping. in fact, Any window type will work. “The most effective approach is to open windows on opposite sides of the house to create cross-ventilation, which helps circulate fresh air throughout the interior of the house,” advises Willits.
Casements, sliding windows or even patio doors that open or slide also work, Willits says, as long as you create a path for air to move through the space. “Even if the house only has windows on one side, it helps to open multiple rooms and interior doors to keep air circulating.” It may be less straightforward, but it can still reduce that stagnant, heavy feeling indoors. Regardless, the principle is the same, Willits says. When conditions outside are safe and comfortable, deliberately opening your windows (even briefly) can help freshen the air inside.
Other ways windows can help keep your home cool this summer
Besides dehumidifying your home, you can increase the performance of your windows to cool your home by taking the following steps:
- Seal air leaks and add insulation: Reduce heat transfer By sealing the small gaps around the windows from the hot air outside to the indoor environment. In fact, improving insulation is one of the fastest ways to reduce unnecessary stress on air conditioning.
- Install a specific type of window treatment: In addition to adding color, pattern and texture to a space, window treatments Helps manage heat. Certain types of shades and curtains increase the insulation capacity of windows by trapping air between the glass and fabric instead of letting it into the room. With the right window treatments, you can keep warm air outside. Roman Shades, Solar Shades, Cellular Shades. and multi-layer thermal curtains are most effective at controlling heat and Keeping energy costs low.
- Apply window film. Another effective remedy is to apply window film Creating an additional barrier between outdoor and indoor air. Look for low-emissivity (low-E) window film that reflects infrared light back to keep indoor temperatures constant.
