VLam™ Hush for Safety, Security & Superior Noise Reduction » Viridian Glass

VLam™ Hush

Acoustic laminated glass

VLam™ Hush is a laminated glass with a specially developed interlayer to dampen noise, providing enhanced sound insulation performance.

The unique noise absorbing qualities of VLam™ Hush reduces sound transmission by dampening vibrations that are associated to noise frequencies such as voices, traffic, trains and aircrafts.

Common solutions for noise reduction involve using thicker glass, VLam™ Hush means that thinner and lighter glass can be used for equivalent acoustic performance.
