Window Glazing Versus Window Film: What's the Difference?

The right window treatment can significantly impact the energy efficiency, privacy, and aesthetics of a home or commercial building. Before making a decision, it is necessary to understand the vital differences between window glazing and window film.

Depending on the circumstances, these window treatments offer unique benefits and limitations, affecting everything from operating costs to tenant comfort. This post explores these options, focusing on window glazing versus window film, concentrating on key areas such as cost efficiency, installation time, and functionality.

What Is Window Glazing?

Window glazing is a term for fixing glass inside a window with a glazing compound, like putty. In a nutshell, it is the pane of the window, and depending on the situation, it can take different forms.

Types

The common forms of window glazing that property owners can adopt include single, double, and triple glazing. Single glazing has one layer of glass, while double and triple glazing include two or three layers of glass separated by air or gas-filled spaces to improve insulation.

Benefits

Window glazing significantly reduces the amount of heat that enters or escapes from your home through the windows. As a result, your house is cooler during the summer and warmer during the winter. This means you won’t need to turn up your air conditioner or heater to maintain a comfortable temperature, and you’ll use less electricity.

Additionally, multiple panes of glass improve acoustic insulation since they reduce outside noise and create a more comfortable environment for occupants. These window treatments can bolster security tenfold, block harmful UV rays, protect interior furnishings from fading, and reduce skin damage from the sun.

Limitations

Window glazing has some shortcomings as a treatment solution. First, condensation can enter between the panes if the seals of your double or triple-glazed windows are not airtight. And since the windows are already sealed, you can't dismantle them to fix the problem. Instead, you have to replace the entire structure, which will cost more.

Second, homes with an older architectural style may have a mismatched layout if you install regular modern-style glazed windows beside the original windows. However, some window glazing companies specialize in making double-glazed units for older homes or can retrofit existing windows. But then again, it could end up costing you more money than other window glazing alternatives.

What Is Window Film?

Window film is a thin, adhesive material applied to an existing window’s interior or exterior surfaces. This window glazing alternative is commonly used to reduce the amount of sunlight that passes through the glass.

Types

Window films come in different types for houses, including solar control films, privacy films, and decorative films. Depending on the type, window film can enhance the performance of existing glazing or achieve different visual effects.

Benefits

According to the International Window Film Association, the transparent window film acts as a solar shield, blocking up to 80% of the sun's heat when applied to a window. This makes it an energy-efficient and cost-effective solution to window glazing. In fact, window film can cut utility costs by 30% to 40% by reducing money spent on air-conditioners and heaters.

Additionally, window films can block up to 99% of harmful UV rays, protecting interior furnishings and reducing glare. For instance, solar control solutions obscure visibility from the outside while allowing natural light to enter, and security films strengthen the glass, making it more resistant to shattering and break-ins.

Limitations

While window films have several advantages, they also have some limitations. For one, window film may peel or bubble over time, especially with extreme weather conditions. Also, exposure to intense sunlight can cause color fading in some window films, compromising their aesthetics. Finally, some window films may not deliver optimal energy efficiency.

Key Comparison Points Between Window Glazing and Window Film

Window glazing and window films have unique characteristics. When deciding between these options for your commercial property, consider these window film comparison points:

Cost

Window films are more cost-effective than installing window glazing. They provide a budget-friendly way to enhance existing windows without requiring major renovations.

This window treatment usually provides the best return on investment since it improves energy efficiency and comfort at minimal cost.

Installation Time and Complexity

Window films are easier and quicker to install compared to window glazing. Maintenance for this option is generally straightforward, but window film may need replacement sooner than double or triple-glazed windows.

Energy Efficiency Impact

Window glazing is usually the best choice for the highest energy efficiency since they have thick insulating layers. On the other hand, window films can improve energy performance but are generally less effective than advanced glazing.

Aesthetic Considerations

Window films are sometimes more appealing than window glazing because they have more customizable designs. For instance, while window glazing is limited to coating and finishes, window film comes in different colors and patterns that provide a variety of aesthetic options.

Maintenance and Durability

Generally, window films are easier to maintain than window glazing, often requiring little or no inspection skill. However, window glazing is a more durable treatment option since it can last for more than 10 years.

Retrofitting vs. Replacement

If you upgrade older windows in your home or office, you need to make sure that the glazing is done properly to ensure the retrofit window’s efficiency. Poorly retrofitted windows can cause condensation issues or even mold in a building.

For window films, retrofitting and replacing are cheap, costing between $20 and $50.

When to Use Window Glazing vs. Window Film

Choosing between window glazing and window film depends on your budget and the level of efficiency you want from your property. If reducing energy costs and improving insulation are top priorities, high-quality window glazing, particularly double or triple glazing, may be the best option. For a more affordable option, solar control solutions like the Exterior Colour Adhesive Window Film provide significant energy savings at a low cost.

In some cases, however, both window glazing and window films may be required to insulate and decorate a property. Additionally, if you are looking for the most energy-efficient solutions, you could use both methods for building energy upgrades.

Final Thoughts

Selecting the right window solution for your property requires you to analyze the difference between window glazing and window film, so you can decide which option is right for you. Each one has distinct benefits suiting different needs, including energy efficiency, privacy, aesthetic appeal, and cost-effectiveness.
