Meaning and boundaries
PVB is a material family with multiple grades; generic naming does not establish thickness, adhesion, acoustic, structural, color, moisture, or security performance.
Why it matters in glass restoration
Exposed edges and some chemicals or prolonged moisture can affect PVB laminates, so manufacturer-specific compatibility is required.
