Tuff-Mass Barrier
  TECHNICAL SPECIFICATION

SOUNDOWN’S Mass Loaded Vinyl Barrier (Tuff­ Mass®) is a specially developed mass layer product offering superior acoustic transmission loss com­bined with good damping properties.

SOUNDOWN'S Vinyl mass/damper sheet offers STC Ratings up to 32. It is a low cost material used for a variety of marine and land based applications. The drawing below shows Tuff-Mass installed as a suspended barrier. This typical appli­cation would improve transmission loss between adjoining spaces.

The combination of the damping and stiffness properties of Soundown’s Mass Loaded Vinyl gives it excellent performance as a combined mass layer and damper when applied to partition panels and lightweight structural bulkheads, reducing trans­ mission of both airborneand structurebourne noise.

Application direct to panels is best done with pre-applied pressure sensitive adhesive (PSA), backed up by minimal fasteners or staples. Soundown’s Mass Loaded Vinyl Barrier exhibits the strength and workability of conventional reinforced Vinyl Barrier materials, without using a fabric layer. This innovation of integral strength and tear resist­ance provides a barrier that is suitable for suspension with mechanical fastenings, without the cost normally associated with a fabric reinforced laminated product.

The standard color of our Tuff Mass Vinyl Barrier is black. Grey or Mylar facing can be applied to our mass loaded vinyl products for further reinforcement. Our Mass Loaded Vinyl Barrier is sold by the square foot on 4.0’ or 4.5' wide rolls up to 500 linear feet.
