W4™

W4™ Windshield Protection Film

W4™ is built around advanced EPU technology to give your windshield an added layer of protection without sacrificing the clarity you expect from factory glass. Its flexible, impact-absorbing construction helps soften and disperse the force from rocks, road debris, and everyday driving hazards before that energy reaches the windshield underneath.

What makes EPU especially well suited for windshield protection is its ability to remain clear, flexible, and resilient at the same time. Rather than relying on a stiff protective layer, W4™ is designed to flex with impacts and recover after deformation, creating a durable sacrificial barrier between the road and your glass. That flexibility also allows the film to conform smoothly across modern curved windshields while maintaining a clean, natural view from inside the vehicle.

Paired with an optically clear adhesive and a durable exterior top coat, W4™ delivers protection you can see working without constantly seeing the film itself. The surface is engineered to resist everyday wear, light scratches, and contamination while helping preserve the smooth, transparent finish of the film over time.

The result is a windshield protection system designed for the part of your vehicle that takes some of the hardest hits. W4™ combines impact protection, optical clarity, and long-term durability into one nearly invisible layer—helping protect expensive windshield glass before damage happens.
