R4™

R4™ Sunroof Protection Film is engineered to protect automotive glass from rock chips, road debris, scratches, and everyday impact without relying on dark absorptive layers that can add unnecessary thermal stress to the glass. Built around a durable 7.5 mil TPU base, R4 provides a flexible impact-resistant barrier while maintaining a clean, factory-like appearance.

Designed specifically for large sunroofs and panoramic glass, R4 delivers 99% UV rejection and up to 98% IR rejection while helping reduce solar heat entering the cabin. Its TPU construction also makes installation more straightforward than traditional heat-shrunk window films, requiring no shrinking while conforming cleanly to the glass.
