Protect from unreal

Protect your lifestyle from unwanted damages with BDF’s Clear Security and Safety 4 mil S4MC window film. Its 4 mil thickness allows the film to serve as a protective layer once applied to your window. The S4MC can absorb impact from break-in attempts and hold shattered glass together in case of breakage while remaining virtually clear and transparent so that you won’t even know it’s there.

DIY Project Friendly

For first-timers, it might initially seem confusing to make the window film stick to the window, but it’s simple! Use two pieces of tape to grab onto one of the corners on each side of the film. Once you start pulling apart the tape, the backing liner should start to peel off from the window film itself. Remember to closely follow the installation manual and use lots of soapy water to prevent the film from sticking everywhere.

99% UV Rejection

Not only does the S4MC security film protect the window from breakage, but it also protects your interior from harmful UV rays from the sun. It rejects about 99% of the UV rays, helping to reduce fading on your precious furniture or other UV-sensitive belongings. Since it maintains the transparency of the window, you can now enjoy the warmth of the sunlight without having to worry about harmful solar rays.
