How Safety Glazing Film Works?

It is made with multiple layers of polyester film that is laminated together. The adhesion works as the base layer, polyester core provides strength, and a security layer helps in resisting breakage.


Key Benefits Of Safety Glazing Film For Cars

Enhanced Safety: This car safety film keeps the glass pieces intact during a collision or accident, preventing them from shattering into dangerous pieces that might harm the passengers sitting close to the windows. It is mostly used for side and rear windows that are typically made of tempered glass and have a higher chance of breaking compared to the laminated windshields.

2. Theft Deterrent: The car window safety film is made in such a way that it is harder to break through. The added resistance works as a shield from theft since windows are harder to smash and require many attempts, additional time, and create noise.

2. Installation Time: Time for installation typically depends on the number of windows and vehicle type; it might take 2 to 5 hours for installation.

3. DIY vs. Professional Installation: DIY kits are available these days, however often lack the durability and clarity of a professionally installed film. A trained personnel ensures a flawless finish, correct alignment, and long-lasting adhesion.
