Security films are a non-invasive investment that strengthen glass, improving safety while reducing glare and heat. However, considering the cost of these films, especially if you have several glass windows and doors, the expense can add up. So, as one does before making any investment, one might wonder: how long do they actually last, and how can one improve their lifespan? In this blog, let’s find out.
Is Professional Installation Worth It?
The very first question that often comes to mind is whether professional installation is even required. After all, it’s just sticking a film onto glass, right? Saying it like that makes it sound easy, but in reality, it’s far from the case.
When you hire a professional for window security film installation, they ensure there are no bubbles or misalignments. One of the biggest DIY mistakes is improper installation, which results in weak adhesion. This naturally leads to premature peeling, and nobody likes that. Lastly, manufacturers only honor warranties if the film was installed by a certified professional. So, while DIY kits might seem like a good idea and a fun project to do on a Sunday, it's highly recommended to just hire a professional so the effectiveness and lifespan of the film aren’t compromised.
The Lifespan of Security Film
We could list over 10 reasons to install security films, but arguably the biggest reason is just how long they can last. Considering they’re a non-invasive addition to glass doors and windows that passively make your home more energy-efficient while clearly adding a whole new aesthetic appeal, they can last about 10 to 20 years if it's a high-quality film. That’s a pretty solid lifespan for something that works 24/7 to protect your home or office. However, that isn’t a given. The durability and lifespan of a film depend largely on:
Film Quality – Naturally, cheap films degrade faster, so always go for high-quality ones from reputable brands.
Installation Quality – As we stated above, poor installation can lead to peeling, bubbling, and premature wear and tear. DIY? Maybe not this one, bud.
Climate Conditions – Extreme heat, humidity, direct sunlight, dust storms, salty air, and other environmental factors can accelerate wear and tear.
Maintenance – Regular cleaning and avoiding abrasive products keep the film looking and performing its best. Speaking of which…
How to Maintain Your Security Film for Maximum Longevity
There is active effort involved in making anything last a long time, and that fact stands true for security window films as well. If you want to make sure your films last as long as possible, follow these simple tips:
For cleaning, use dedicated security film cleaners or mild soap and water. Do not use harsh, ammonia-based cleaners, as they break down the adhesive over time.
Do not clean the windows with a piece of cloth you’re looking to get rid of or toilet paper. Use a soft microfiber cloth or a rubber squeegee only to avoid scratching the surface.
While not always necessary, keeping the indoor climate as stable as possible helps prevent stress on the adhesive.
Most reputable companies claim their security films last a solid 10-15 years, even offering warranties throughout this time span. But with the right care, they can potentially last even longer.
What Makes Security Film Durable?
Security films are designed to last a long time. Companies that make them have spent a significant sum of money on R&D to create a product that is both durable and effective. A high-quality film is usually durable due to the following:
Strong & Flexible Materials
They’re made from polyester (PET) or polyethylene (PE), multiple layers of it, making them resistant to tearing, impact, and daily wear and tear.
Powerful Adhesion & UV Protection
A strong adhesive layer keeps the film securely attached to the glass, preventing bubbling and peeling. While security films can block UV rays and reduce glare, direct sunlight can still cause damage. That’s why UV inhibitors are used in their composition to prevent material breakdown, fading, and discoloration.
Scratch & Impact Resistance
A scratch-resistant coating helps the film stay clear and smooth, even with frequent cleaning. Tear-resistant properties and impact-resistant additives make it tough to puncture, ensuring long-term durability.
Special Features & Longevity
Some films offer extra protection, like blast resistance or graffiti protection. Tinted options not only reduce heat and glare but also extend the film’s life by minimizing sun exposure.
Final Thoughts
Glass door security films serve multiple purposes and are one of the easiest upgrades anyone can make to improve the safety, energy efficiency, and aesthetics of their home.
