Have you ever wondered how modern buildings keep noise out while using large glass windows and walls? One of the secrets lies in a smart material called PVB interlayer film.
Used in laminated glass, PVB interlayer film not only adds strength and safety but also plays a big role in sound insulation. This blog explores how it works, why it’s important, and where it’s used in real-life buildings.
Understanding PVB Interlayer Film: The Silent Hero in Laminated Glass
PVB (Polyvinyl Butyral) interlayer film is a special plastic layer placed between two pieces of glass. The glass and film are heated and pressed together to create laminated glass. This process bonds the glass and film tightly, so they act as one strong unit.
Laminated glass is used in cars, buildings, and public areas because it’s safer and stronger. But one benefit people often overlook is how PVB interlayer film helps reduce noise.
