VLam™ Hush uses a specially developed interlayer which further enhances the noise insulation properties of the glass. It reduces the coincidence dip even further than both float glass and standard laminated glass which means that the sound insulation properties found in much thicker glasses of each type can be achieved in a product that is both thinner and lighter. For example, when comparing the sound insulation properties of 6.5mm VLam™ Hush over 6mm float glass; VLam™ Hush improves the sound insulation by over 24%.
