To keep heat out of windows, apply reflective window film to block UV rays and reduce heat gain. Use thermal curtains or shades to insulate the windows and keep rooms cooler. Weather stripping around the window frame helps seal gaps and prevents hot air from entering. These methods improve energy efficiency and reduce cooling costs in hot weather.

Heat can be blocked from entering through windows by applying reflective window film, using thermal curtains, and sealing gaps with weather stripping. These methods help reduce cooling costs, improve comfort, and increase energy efficiency during hot months.
