Putting cling film on single glazed windows does in fact help to reduce energy loss. By providing a second barrier to heat transfer, it creates a very basic – and inexpensive – 'double glazing' system.
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.
If you can successfully fit an airtight layer of cling film over a single glazed window then it will trap a layer of air which can reduce heat loss and make your house warmer.
Savings in Energy and Money
Window film covers are inexpensive, reduce drafts, help the house feel warmer during winter months, and reduce moisture buildup on the window due to condensation.
Since adverse weather conditions impact the outside of your window, you should use stronger plastic if you place it there. It needs to withstand strong winds, snow, blizzards, and heavy rains. The negative side of outside plastic concerns an aesthetic issue since it doesn't look nice.
Because clingfilm is a good insulator, this charge persists for quite a while. When you wrap the clingfilm around itself or another insulator (like glass) the electrostatic charge induces an opposite charge in the other surface and the two stick together.
Window film isn't the only step you can take to add extra insulation to old single pane windows. If you notice any drafts coming in around the edge of the frame, you can also attach window insulation tape. This is a padded, foam-like tape that will absorb stray gusts that squeak through between the glass and the frame.
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.

Does window film cause seal failure in double glazed units? No. A typical double glazed unit is constructed with two panes of glass with a spacer bar at the edge separating the two glass panes.
Plastic as a window application is relatively transparent, making it a fair substitute to glass. And, it's a cheaper alternative to installing new energy-efficient double glazed windows. But, there's a catch. Installing window film for thermal insulation isn't actually that effective.
Removing condensation
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.
To prevent heat loss through the movable parts of your windows, such as the gaps between the sash and the window frame, you can apply temporary insulation called weather sealing strips. Using EPDM, foam or felt stripping, you can cut the product to size and apply them over all the seams and gaps of your windows.
In fact, changing the way Saran Wrap works came at a huge loss to the parent company, SC Johnson. The original wrap contained a chemical that's toxic to the planet. Polyvinylidene chloride, or PDVC, is the polymer in plastic wrap that makes it stick to itself so well.
But how do they work? Window insulation film weatherizes your home by blocking cold air from entering and hot air from leaking through the windows in the winter, and vice versa in the summer.
Yes, plastic wrap can be used in the microwave. It is recommended that users poke holes for steam ventilation. The plastic wrap should not come into contact with food high in fat. The fat can melt the plastic wrap if heated to a high enough temperature.
An insulating window film applied over a window can help the window retain up to 55 percent more heat in winter, potentially reducing your heating costs up to 30 percent. These films are less effective at reducing summer heat gain, though.
Putting the film on the outside would only expose it to weathering elements, so by putting it inside, it's better protected. Before putting up the plastic film, first take down any curtains, drapes or blinds so you can more easily reach the inside of the windows.
