PVB Interlayer Performance Requirements for Laminated Side Glazing

Laminated side glazing is a rapidly growing new application, driven by consumer demand for improved intrusion resistance and increased comfort. Performance requirements for movable door glass applications are different from laminated windshield (LWS) needs. Criteria for satisfactory performance are discussed and the performance of commercially available interlayers compared. Performance differences are significant, indicating that interlayer selection is critical for acceptable side glazing performance. The most important performance attribute is the ability to maintain adhesive bond strength to glass at the high interlayer moisture content present at exposed edges.
