All Whisper Walls systems are designed to securely hold fabric without the use of adhesives, nails, tacks or tape. There are thousands of fabrics in different styles, patterns and colors that work well in the Whisper Walls systems but some fabrics do not. When selecting a fabric, there are several items that must be considered to ensure success, they are as follows:



FIRE RATING Confirm Class A rating in accordance with:
  • ASTM-E84
Fibers that are stable and work well:
  • Polyester; and
  • Polyolefin
Fibers that work but may require further stabilization:
  • Cotton;
  • Silk; and
  • Wool
Fibers that are unstable and should be avoided:
  • Nylon;
  • Rayon; and
  • Viscose
Panels being used to absorb unwanted noise should be faced with fabrics that have an open weave and freely allow air to pass through them. Fabrics that cannot be blown through with ease should be avoided.
Panels being used as a tackable surface should be faced with fabrics constructed with a plain weave from durable fibers like polyester. The material should have self-healing characteristics. Satin weaves are not recommended.
Some light colored or lightweight fabrics may be visually transparent in certain lighting conditions. This means they allow the materials behind them to be seen on the surface. When selected, these fabrics will require the installation of a liner fabric which will increase the installation costs.
Knit backings and lightweight acrylic backings can be used with success but acoustical performance may be diminished. Paper backed fabrics cannot be used.
The Whisper Walls stretching systems allow for the precise matching of both patterns and repeats at all seam locations. In general, smaller patterns and repeats reduce waste and installation costs.
