Insulated windows will still let sunlight through but better keep out the heat and cold. 

Windows can be a relatively costly home feature, accounting for solar heat gain during the summers and substantial heat loss during winter. Effective window insulation limits heat loss and also helps regulate the temperature of the interior glass. They are also incredibly effective since they increase energy efficiency in your home.

Next, assess where the heat gain or heat loss. Again give some attention to the type of windows you are thinking of insulating. Finally, before selecting the insulation method from the available options, you should again consider your objectives.

Temperature regulation is our main objective here, but you also must think about how much to increase the insulation value and what tradeoffs you are ready to make.

Since the primary source of heat loss is not via the glass but through the apertures in the window frame and the sashes rattle. You could easily use a hammer and a pry bar to extract molding from around the window. Then cut a stripe of foil-faced rigid foam insulation to fit into the space between the side jamb and drywall. When that is done, drizzle some maximum-expanding polyurethane foam adhesive into the space at the bottom and top of the window.

4. Weatherstrip

The weatherstrip is easy to go to, a method that will work for both winter and summer days. During summer, you will be able to keep hot air out and cool air in and in the winter, you wil also be able to keep warm air in and cold out.
