Insulating windows in winter can reduce heating costs and make your home more energy-efficient. Follow our easy how-to guide to get your windows ready for the cold.
If you’re interested in making your home more energy-efficient and reducing your heating costs this winter, you may be looking into adding extra insulation to your home, installing weather stripping or caulking up cracks in windows and walls.
In addition to the solutions mentioned above, you can also reduce your family’s utility bills by taking advantage of insulation film. Window insulation film is a plastic film that's pasted on windows to reduce internal and external heat transfer. It helps reduce heat loss in winter by trapping the heat inside, and it also reduces heat gained in summer by reflecting the sun’s heat.
There are multiple advantages of using insulation film in winter:
Insulation films are energy-efficient solutions that result in significantly lower utility bills. A study by CCHRC (Cold Climate Housing Research Center) found that insulation film provides a thermal improvement roughly equivalent to adding another windowpane and resulted in a 33 percent thermal improvement.
Insulation films are readily available and inexpensive, and they pay for themselves in less than a year. They're a cheaper alternative to replacing windows, which can be a major expense.
Insulation films also prevent condensation, which occurs when the temperature inside your home falls below frost or dew point. By preventing condensation, films reduce heat loss around the clock.
Insulating films also reduce fade damage to your home's furnishings, floors and window treatments by blocking out up to 99 percent of UV (ultraviolet) rays.
Before you start insulating windows in your home, it is important to be selective when choosing which windows you’ll be insulating. Once the film is installed, the window can then only be opened after removing the film. Windows that get opened often should ideally not be insulated for this very reason. Leave one window free in rooms like the kitchen, where you might want to crack a window in case of a smoky cooking mishap.
Once you've chosen the windows you’ll be insulating, the next step is to get heat-shrink film and some double-sided tape from your local hardware store. Alternatively, you can buy a window insulation kit. Follow these steps to install heat-shrink film on windows:
While this process isn’t quite as simple as installing curtains, learning how to insulate windows for winter using insulation film is easy to do on small and moderately sized windows. While film is an affordable and convenient alternative to reducing your utility bills a more long-term solution would be to replace your windows.
