It will save energy, meaning your bills for gas and electricity will be less than usual. Not only will plastics keep your home warmer during the winter, but it can prevent the cold air from your window air conditioner from going out of your home during the summer.
Plastic window film covers can reduce drafts and make your home feel warmer during the winter. They are also a relatively inexpensive way to reduce condensation buildup and lower energy bills. Window wraps can also seal air leaks around the window, when those leaks extend over woodwork.
When you're dealing with old, drafty windows, you essentially have two options: replace them or seal them with insulating window film—a.k.a. plastic wrap. This kit by 3M—a leader in consumer products—insulates up to five windows, and the company claims it lowers heating costs and saves energy.
Using Plastic Window Film
The film, which looks similar to cling film, is applied on the inside of the window. Putting the film on the outside would only expose it to weathering elements, so by putting it inside, it's better protected.
When warm, moist air comes into contact with cold window glass, water droplets form on the window's surface. Plastic film stops the formation of condensation on the interior of your window glass by creating a barrier between the air and the glass.
For example, excess water can cause window seals to warp and loosen, while the excess damp can lead to mould and respiratory problems. Make a habit of removing window condensation first thing every morning — when it's at its worst.
Acrylic Plastic Sheet
Acrylic is a popular choice for windshields, drive up windows and similar applications. It is particularly resistant to UV radiation, which makes it ideal for outdoor recreation applications, including vehicle and marine use. It will resist scratching better than glass and is fairly easy to seal.
That plastic strip is called glazing bead.
To winterize your windows in plastic, you need to place a heavy plastic sheet over your windows, taping it tightly to the walls or sill, and use heat to tighten the plastic to a smooth finish. The end result is a window without gaps or drafts, which still allows sunlight to enter and warm the room.
Keeping Cold Air Out
The plastic film is also an insulating film. When correctly installed over the face of the window, it blocks cold air from entering the home through windows, which will also stop the warmer air from leaving.
The best way to winterize your windows is to add a sealed layer of plastic or glass over the window. And the cheapest, easiest way to do this is by installing an interior window insulation kit. Duck brand Shrink Film Window Insulation Kit and 3M Window Insulator Kit are two readily available options.
A material like plastic could easily get warped or wear down and you would have no idea. It could be potentially useless, and since there's no way of you knowing, you wouldn't know to replace it. Another reason is because glass is a very hard material.
Fortunately, scientists, engineers and designers are shifting their focus to ecologically friendly alternatives that create circular, low-waste ecosystems – liquid wood, algae insulation, and polymer substitutes made from fermented plant starch such as corn or potatoes, for example.
Many homes now have plastic window glazing and frames. Also known as Plexiglass, acrylic is used as a substitute for glass in window panes. While more expensive and less scratch-resistant than glass, acrylic is lighter and less prone to shattering.
To help with clearing the condensation away, you can make a simple, home-made solution by mixing two cups of water with two cups of white vinegar and a couple drops of washing up liquid. Pour this mixture into a spray bottle if you have one and spray the solution straight onto your window.
When cold weather sets in, condensation can appear on windows and sliding glass doors. Often called "sweaty windows," the condition is the result of high humidity and low temperatures. It can block the view, drip on the floor, and freeze on the glass.
Excessive humidity is the cause of most window condensation. As the outside temperature drops, the window glass temperature also drops. When moist air comes in contact with the cold glass pane, the moisture condenses and forms water droplets.
Just keeping your window open for a short amount of time each day can significantly reduce indoor pollution and bring fresh air inside to dilute any toxins. In winter, especially, air can become old and stale quickly, so you'll want to keep things fresh and clean.
Blinds can't cause condensation due to the fact they do not produce moisture or heat.
