Product Overview

BDF S4MB35 Security Window Film combines 4 mil safety and security film construction with a medium Black 35 tint, providing added glass protection and solar control while maintaining natural light and outward visibility.

The film is designed to help hold shattered glass fragments together following impact, which can help reduce hazards associated with broken glass. Its 4 mil construction adds a protective layer to existing glass during accidental impacts and attempted forced entry. It should be considered an added protective layer rather than making the window break-in or impact proof.

The Black 35 medium shade offers a balance between natural light, outward visibility, and solar control. It provides some daytime view-shielding while helping reduce solar heat and glare, making it a good choice when moderate shading is desired without significantly darkening the windows.

S4MB35 also provides up to 99% UV rejection, helping reduce UV exposure that can contribute to fading of interior furnishings. Because its medium tint provides only mild view-shielding, this film is best suited for security and sun control rather than dedicated privacy.
