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.

Considerations
Installation
- For an accurate sound assessment, all elements of the building envelope need consideration in order to develop an accurate acoustic solution. This includes window frames, walls, floor and roof materials which all influence sound transmission.
- Ensure any airgaps and frames are well sealed to avoid noise leaks, poorly sealed spaces will leak both air and noise.
How to Specify
- Available in Clear, Grey and Translucent.
- Select from: laminated or insulated glass unit.
