Product Overview
BDF S4MC Clear Security Window Film is a 4 mil safety and security film designed to add protection to existing glass while maintaining a clear, unobtrusive appearance.
The film helps hold shattered glass fragments together following impact, which can help reduce hazards associated with flying or falling glass. Its 4 mil construction adds a protective layer to existing windows during accidental impacts and attempted forced entry. It should be considered an added protective layer rather than making the window break-in, impact, or storm proof.
S4MC passes ANSI Z97.1 Class B and CPSC Category 1 testing requirements, making it a practical option for applications where safety performance is an important consideration.
The clear construction maintains natural light, outward visibility, and the existing appearance of the glass while providing up to 99% UV rejection to help reduce UV exposure that can contribute to fading of interior furnishings.
S4MC is not intended for heat control or privacy. Choose this film when the primary priorities are safety, security, UV protection, and maintaining clear visibility.

- Spray abundantly. A fully wet window & film is the key for successful installation.
