It really works, and it can increase a window's insulation for many months. Additionally, insulation film lets in sunlight—which can further warm a window. This side benefit is commonly overlooked, but it's incredibly valuable. Any natural heat gain is beneficial—reducing a heating system's work throughout the day.
Using Plastic Window Film
Plastic window film can be an inexpensive alternative to double-glazing windows. 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 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.
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.
The standard today is a double-glazed low-E window with insulation between the panes. A vast improvement over a single pane, insulated windows are better at preventing heat loss and heat gain, keeping the internal temperature of a house relatively stable.
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.
Under the right conditions, quality film for windows can last for as long as you own your home. Many homeowners have gotten 20 years or more out of their tinting systems.
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.
This moisture build-up on the glass can make your home feel damp, 'muggy,' and uncomfortable and lead to possible mold growth if not careful. Putting a layer of plastic sheeting over your windows can help stop winter condensation from causing a problem in your home.
Is plastic wrap a good insulator? No, plastic wrap does not have very many qualities that make it an excellent insulator. It may slightly assist in heat retention, but aluminum foil is a better insulator. Two layers of plastic wrap with air in between are the best way to use plastic wrap as an insulator if necessary.
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.
Some obvious signs and symptoms that your home has air leaks and can benefit from plastic sealing are: Rattling windows. Visible gaps around the window or door trim. Noticeable pests and dust entering through gaps or holes in or around the window or door.
Window insulation film can mean as much as a 30% to 40% decrease in your utility bills. Window films are one way to make your windows more energy efficient. You might be able to save up to 19kWh per square foot of glass on your energy costs.
Condensation on the exterior of your windows is a normal process, typically caused by high humidity levels. While this is more common in the summer months because of increased humidity, it can still occur in the winter.
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.
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.
Condensation on windows occurs because water vapour in the air deposits itself on surfaces that are at lower temperatures. When moist air comes into contact with the cold impermeable surface of your windows, it releases some of this moisture onto the glass as water droplets. This is condensation.
3M window tints are considered the top-choice by made car manufacturers and providers. The quality of the product ensures that you will be getting a valuable commodity that can make the difference for your vehicle in the long-term.
3M Sun control window films are very durable and designed to last for many years, just how long will depend on the type of film applied, type of glass, climatic conditions and care. Based on our experience, films will last 10 to 15 years.
Window film blocks radiant heat flow, keeping hot air out in the summer and making it easier for your air conditioner to do its job. Window film benefits older homes particularly. They usually have windows that aren't very efficient in blocking heat or UV rays.
