Gardstrike Defense Window Film is security film and premium tint in one. When glass is struck, the film helps hold the fractured pane together — so a smash and grab takes time, effort, and noise the thief didn't plan on.
Defense is a 4 mil vehicle security film that does two jobs at once — it delivers the look and heat performance of a premium tint, and it adds a layer of protection your standard tint was never built to provide.
Standard film is measured by how much sun it blocks. Defense is engineered to hold damaged glass together when a window is struck. The glass still breaks — but it doesn't fall away, so getting through it takes repeated effort and time out in the open.
Most window film is rated on how much sun it blocks. Defense is built for what happens the moment the glass gets hit.
Engineered for heat rejection, glare, and appearance. It does that job well — but it was never designed to do anything when the window is struck.
The same premium look, shade options, and 99%+ UV blocking you'd expect from a quality tint — with a heavier build engineered to hold damaged glass together.
The goal isn't unbreakable glass. It's to make breaking in take long enough that the risk of getting caught outweighs the reward — and most attackers move on.
You're already putting film on the glass. Defense asks it to do a second job while it's on there.
The whole method depends on being fast. Defense helps hold shattered glass together after impact, so getting a hand through the opening takes repeated effort out in the open.
At a red light or in slow traffic, the window is the only thing between your passengers and the street. Defense adds a real barrier where there used to be just glass.
Over 99% UV blocking, four shade options, and a color-stable finish backed for five years — without giving up appearance, comfort, or the signal on your phone and navigation.
For a little more, you get a lot more. If you're already paying to have film installed, the question isn't whether you want protection — it's whether you want the version that only handles sunlight.
Defense is a 4 mil automotive film built to hold up to daily driving — sun, car washes, window cycles, and the occasional bad night. Here's exactly what you're getting on the glass.
The thickness is the product. A 4 mil build is what allows the film to hold a fractured pane together instead of letting it drop into the cabin — and it's what separates Defense from the film most vehicles are wearing.
Defense is backed by a ten-year warranty when installed by an authorized Gardstrike installer. Your installer can walk you through the full terms before the film goes on.
Defense is available exclusively through authorized Gardstrike installers. A 4 mil film is heavier and less forgiving than standard tint — the fit has to be precise, and the five-year warranty depends on it being done by a trained shop.
Your installer will confirm which shade is legal in your state and quote your vehicle before any film goes on the glass.
