Yes, putting plastic over windows can help reduce condensation by creating an insulating air pocket, keeping the inner glass surface warmer and minimizing the temperature difference that causes moisture to form, but it must be sealed perfectly; an imperfect seal traps moisture, potentially creating worse mold issues. Window insulation kits are an effective DIY way to add this thermal barrier, reducing drafts and condensation, but proper sealing is crucial to prevent moisture buildup within the film, according to videos and articles from Home Repair Tutor and Energy Star https://www.youtube.com/watch?v=3PkFKG4b7ic, https://www.youtube.com/watch?v=tbq6uZ9Y0nQ,.
To prevent condensation on your windows this time of year just simply rub neat washing up liquid using a dry cloth all over the effected windows and this will stop the condensation leaving you with dry windows in the morning.
This means that your top choices are Venetian blinds, faux-wood, and real wood blinds, and also vertical blinds, all of which have tiltable or rotatable slats or louvres.
I recommend heavy duty clear vinyl on the outside. I have done it the past 2 winters after doing window film on the inside my first winter. It insulates much better (could still feel cold air with window film on inside) and I have no condensation.
This is where cling film could prove useful, the expert suggests. He said: "Putting cling film on the inside of your windows may seem odd, but this creates an extra layer of insulation by trapping air between the glass and the plastic. It's also a much cheaper alternative to 'official' insulating films."
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.
Regular window films simply aren't designed to reduce interior fogging. However, that's not to say they can't become one of the window condensation solutions if you opt for specialized anti-condensation film.

Potential Cons to Consider
According to Energy.gov, plastic window insulation can save you 10%–30% on heating and cooling costs. While plastic window sheeting may have some downsides, it is reasonably effective as a wintertime insulator.
To help prevent excessive condensation, insulate between the window head and platform. Adding extra insulation between the window head and platform can also help in very cold climates.
Should You Wipe Condensation Off Windows? Yes, wipe off any condensation on your windows with a soft microfibre cloth. It's one of the first things you should do. Not only does it protect your windows and sills, but it also helps maintain healthier indoor air quality by stopping mould from growing.
Condensation happens because rooms get too cold, they fluctuate between cold and hot, and there is excessive moisture from cooking, washing and expiration. The biggest causes are showering, drying clothes on radiators and boiling pans. Underlying issues of damp can also be a persistent problem.
Salt is hygroscopic, meaning it naturally attracts and absorbs moisture from the air. When placed next to a cold window pane, it can help reduce the amount of water that collects overnight — particularly in small rooms or on single-glazed windows.
Yes, you should wipe condensation off your windows. In fact, if this happens regularly, it's a good idea to get into the habit of removing it every single day, recommends Stephen Hankinson, Heating Expert at Electric Radiators Direct.
Install Window Film on Double-Pane Windows: The Risks
The main reason is that window film will increase the temperature of the glass it is on which could cause thermal stress.
If it's brighter outside, then you will be able to see through the film from the inside out. If it's brighter inside (usually at night when lights are on in the home) then it will be possible to see through window film at night from the outside in.
Debunking the Myth. Applying window film doesn't break glass on its own. However, it can contribute to thermal stress or exacerbate pre-existing weaknesses in the glass.
While cardboard may not be the most conventional material for window insulation, it can still provide significant benefits in terms of heat retention and energy savings.
Weatherstripping involves applying materials like foam tape, V-strips, or felt around window frames to seal gaps where air can escape. It's one of the easiest and most affordable insulation methods, ideal for double-hung or sliding windows.
While condensation may seem like a minor issue, it can lead to bigger problems such as mold growth, water damage, and even structural issues. One of the most effective ways to combat these issues is by properly sealing your home's windows, doors, and other entry points.
How to Stop Condensation on Windows Overnight in Winter
THE TEMPERATURE OF YOUR HOME
Cold air is more likely to deposit droplets of condensation around your home. Air is like a sponge, the warmer it is, and the more moisture it will hold. Heating one room to a high level and leaving other rooms cold makes condensation worse in unheated rooms.
You might be wondering how this magical film works its wonders. Well, insulating window cling film uses the power of trapped air between your window and the film to create an insulative barrier. It's like putting on an extra layer before heading out into the cold—only this time, it's for your home!
