How Long Does Smart Film Last?

Smart film has a general lifespan of at least 10-15 years, making it a reliable and versatile privacy solution for homes and commercial spaces. After the 10-year mark, some slight yellowing may occur, especially with prolonged sun exposure, though this effect is minimal and only noticeable when compared directly to clear glass.

Compared to smart glass, smart film has a shorter lifespan primarily because it isn’t as protected. Smart glass sandwiches the switchable layer between two layers of laminated and tempered safety glass, which shields it from moisture and damage. In contrast, smart film is applied directly to the surface of the glass, leaving it more vulnerable to environmental factors like weather or wear and tear. That’s why Smart Glass Country offers a longer warranty for smart glass—up to five years—while our smart film comes with a one-year warranty.

‍

Despite the differences in longevity, both smart film and smart glass are innovative, long-lasting privacy solutions that outlast most conventional window treatments. Here's an in-depth look at what determines the lifespan of smart film and how you can maximize its longevity.

‍

Factors That Impact Smart Film Lifespan

‍

Several factors determine how long smart film will last, including:

‍

1. Film Quality

   Higher-quality smart films last longer. Premium PDLC films are less prone to peeling, bubbling, or discoloration compared to cheaper alternatives. When investing in smart film, choose a reputable brand known for using durable components.

‍

2. Installation Method

   The way smart film is installed has a significant impact on its lifespan. Proper application without bubbles or creases ensures better durability. Hiring a professional installer is recommended to avoid common issues that occur with DIY installations.

3. Sun and Weather Exposure

   Smart films that are constantly exposed to direct sunlight—especially those on south or west-facing windows—may degrade faster due to increased UV exposure and heat. Films installed on windows with minimal direct sun exposure tend to last longer.

‍

4. Glass Quality

   Smart films perform best on smooth, modern glass surfaces. Older or damaged glass, which may be wavy or contain impurities, can lead to uneven adhesion and premature failure.

‍

5. Power System and Electronics

   The electronic components that control smart films need to be of high quality to avoid malfunction over time. At Smart Glass Country, we test our electronics rigorously to ensure they match the longevity of our films.

‍

6. Maintenance and Care  

   Like any technology, smart films require basic maintenance. Keeping the glass clean, addressing any peeling edges immediately, and avoiding harsh chemicals can help extend the life of the film.

Smart Film vs. Smart Glass: How Do They Compare?

‍

When compared to smart film, smart glass offers longer-lasting performance. The primary reason is that smart glass protects the switchable layer from environmental exposure by encasing it in glass. This extra protection makes smart glass a better option for areas with high sun exposure or heavy use, where longevity is a priority.

‍

On average, smart glass can last anywhere from 20 to 30 years, while smart film typically lasts 10 to 20 years depending on the conditions and maintenance.

How to Extend the Life of Smart Film

‍

To get the most out of your smart film, follow these best practices:

‍

- Seal the Edges: After installation, it’s important to seal the edges with a neutral cure silicone to protect the film from moisture. Proper sealing will prevent water damage, which can cause irreparable harm to the film.

‍

- Monitor the Sealant: Over time, the sealant can degrade, allowing moisture to seep in. Regularly inspect the sealant and replace it if necessary to keep the film in good condition.

‍

- Protect Against Sun Exposure: For windows with direct sunlight, consider adding exterior shades or tinting the exterior of the window to minimize UV exposure.

‍

- Clean Gently: Use mild soap and water to clean smart film. Avoid abrasive cleaners or scrubbing tools that could scratch or damage the film.

‍

- Repair Early: If any edges begin to peel or bubble, address the issue immediately to prevent further deterioration.

Typical Lifespan of Smart Film

‍

With proper care and installation, you can expect high-quality smart films to last between 10 to 20 years. Factors like exposure to the elements, the quality of the glass it's applied to, and regular maintenance all play a part in determining its longevity. 

‍

For those in areas with heavy sun exposure or who plan on high usage of their switchable glass, smart glass may offer a more durable and long-lasting solution.
