CRYSTAL FOR ACOUSTIC ISOLATION LAMINATED GLASS WINDOW.

摘要

The present invention relates to a crystal for acoustic isolation laminated window, including at least a plastic film giving it high or low damping properties. The present invention proposes to combine a high acoustic functioning with another film, having ordinary acoustic functioning such as PVB. Both films can be separated by an impervious thin film, such as polyethylene terephthalate. Acoustic results are as good as with acoustic film alone.
