Viridian VLam Hush™

A sound solution to effective noise reduction

Description

Viridian VLam Hush™ is a laminate that uses a specially developed interlayer to dampen noise, providing enhanced sound insulation performance. This means that thinner and lighter glass can be used for equivalent acoustic performance. VLam Hush reduces the coincidence dip of standard monolithic and laminated glass.

Considerations

Vents in the wall provide a simple entry point for noise. In most houses there is a gap between the roof and the ceiling above the external walls which allows noise into the ceiling space. If the house is built on stumps then noise has access to the under floor space. Windows and doors which do not seal well will also allow noise to pass around their frames, so a proper assessment of the entire building is required in order to develop an adequate solution.

Features and benefits

• Laminated Grade A safety glass
• Available in 6.5 to 12.5mm thicknesses in 3660 x 2440mm
• Can be incorporated with other solar control options
• Can be incorporated in a ThermoTech insulating glass unit
• Compared to 6mm float glass, 6.5mm VLam Hush reduces noise by over 40%

Specific to New Zealand, VLam Hush is manufactured as a CIP Laminate where two sheets of glass are bonded together using a specifically formulated noise reduction resin as the sound reducing interlayer. The CIP laminating process provides a wide range of glass options and is particularly suited for toughened laminated glass. It is manufactured with a clear edge tape to separate the glass before a UV cured resin is used to laminate the glass and produce a Grade A safety glass.
