Now that summer has arrived so has the long hot days which can bring uncomfortably high indoor temperatures. While air conditioning is a popular solution, it can be costly and energy-intensive. Fortunately, you can use your windows strategically to keep your home cooler. Here are some effective ways to make the most of your windows and maintain a comfortable indoor environment during the summer months.

1. Optimize Natural Ventilation

Using windows for natural ventilation is one of the best ways to cool your home without relying on air conditioning. By allowing fresh air to circulate, you can expel hot air and bring in cooler air.

Tips for Natural Ventilation:

  • Open windows in the early morning and late evening: These times of the day are typically cooler, allowing you to capture the refreshing outdoor air before the temperatures rise.
  • Create a cross-breeze: Open windows on opposite sides of your home to facilitate airflow. This helps push hot air out and pull cooler air in.
  • Use fans to boost airflow: Place a fan near an open window to draw in cool air or direct a fan outward to expel warm air from the room.

2. UV Coatings

retrofitting your home’s windows with UV coatings filter some of the light entering your home, making it much cooler and more energy efficient throughout the summer.

Adding a low-E coating sun shield coating to your windows can help keep the unwanted heat and UV rays on those hot summer days.

3. Double or Triple Pane Glass

Going with a double or triple pane glass on your new windows is highly recommended when going for a low-E glass. The argon gas in between each pane of glass helps to keep you more comfortable in your home, provide moisture protection, reduce solar gain, and adds and extra layer of insulation to your home.

4. Apply Heat-Reducing Window Treatments

Heat-reducing window treatments are designed to minimize the amount of heat that enters your home. These treatments can be both functional and stylish.

Types of Heat-Reducing Window Treatments:

  • Thermal curtains: Made with insulating materials, thermal curtains can block heat from entering your home while also keeping the cool air inside.
  • Blackout curtains: These curtains are designed to block out all light, including heat from the sun, making them an excellent choice for keeping your home cool.
  • Window blinds with reflective coatings: Blinds with a reflective coating can help reduce heat gain by reflecting sunlight away from your windows.



Keeping your home cool in the summer doesn’t have to rely solely on air conditioning. By using your windows strategically, you can take advantage of natural ventilation, reflective coverings, shading solutions, and heat-reducing treatments to maintain a comfortable indoor temperature. These methods not only help keep your home cooler but also contribute to energy savings and a more sustainable lifestyle. Implement these tips and enjoy a cooler, more comfortable summer at home!
