SONEX ProSPEC Foam and SONEX ProSPEC Composite are available with a peel and stick adhesive PSA.  We also make a ceiling tile noise barrier which is a thin, uncoated version of our melamine composite for use on top of ceiling tile / drop-in ceilings or for adhering to walls and ceilings.

SONEX ProSPEC foam is made of a 1” fire resistant melamine foam with a light gray cleanable HPC coating.

ProSPEC Composite is the same as SONEX ProSPEC but adds adds a 1 lb./sq.ft. noise barrier that prevents noise from going through the material, stopping the sound in addition to absorbing the sound.

Additional Information

PROSPEC Foam

Physical Data
Sound Absorption Data

Size

  • Typical panel size: 24″x 48″ (610 x 1219 mm)
  • Typical thickness options: 1″

Applications

  • Ideal for controlling excessive machine noise
  • Excellent sound absorption across all frequencies
  • Production facilities

Material

  • Made from open-cell natural light grey WILLTEC® expanded melamine foam
  • HPC-coated for added durability

Direct-Apply, Glue-up Installation

  • Use clean, thin, white cotton gloves to handle panels
  • Cut acouSTIC™ adhesive cartridge tip to produce ¼ inch (6.4 mm)-diameter bead
  • Run a continuous bead of adhesive around the panel’s perimeter, approximately 1.5 inch (38 mm) from edges, then apply intermittent beads from opposite corners through the center of the panel creating an X
  • Press panel firmly into place and smooth evenly across it to ensure a strong, lasting bond; adhesive tack should be immediate

PROSPEC Composite

Physical Data PROSPEC
Sound Absorption Data

Size

  • Typical panel size: 24″x 48″ (610 x 1219 mm)
  • 1″ (25 mm) thick layer of water-based HPC-coated willtec foam, to absorb noise.
    1/8″ (3 mm) thick noise barrier, to contain noise and reduce sound transmission.
    1/4″ (6 mm) thick willtec decoupler to provide air space between the barrier and the mounting surface for optimal noise containment. This decoupler helps to insulate the barrier from vibrations in the wall.

Applications

  • Over substandard walls between manufacturing plant and offices
  • To line thin enclosures around machinery, air compressors or similar noise sources
  • In engine compartments, under machinery hoods

Material

  • PROSPEC Composite combines the benefits of both willtec® acoustical foam and the noise containment capabilities of vinyl barrier into one durable product. The panels come standard with a convoluted surface and gray water-based HPC facing for easy clean-up. Rugged Tedlar® facing is available to withstand harsher chemicals and cleaning. Aluminized Mylar® is also available for special applications.

Installation

acouSTIC adhesive (part number PA-02) has been specially formulated to use with all SONEX®, WILLTEC®, CONTOUR®, WHISPERWAVE panel products, PROSPEC® Foams and Composites. This nontoxic, practically odorless, water-based adhesive makes direct-apply, glue-up installation work quick and easy. acouSTIC adhesive provides an immediate tack between panels and most substrates making for strong, permanent bonds. Other adhesives may not be compatible and may emit an odor.

acouSTIC Foam Adhesive

Features

Nontoxic, water-based adhesive.
Easy cleanup with soap and water.
Compatible with both polyurethane and WILLTEC foams.
Each 10.3-ounce (304.61 ml) tube installs between 16 and 24 square feet (1.49 and 2.23 square meters) panel coverage.
Tube fits standard caulking guns.

General Installation Notes

Handle with care. Do not pick up or handle panels by the corners.
Store panel boxes flat in clean, dry areas protected from the elements; excessive heat, cold and humidity.
Do not set or stack anything on top of cartons.
Work panels with clean hands, tools, ladders, etc. on clean work surfaces. Wear clean, soft white cotton gloves to handle panel installation, recommended.
Super sharp, stainless steel smooth long-blade insulation knives are ideal for making straight cuts, slicing through thick WILLTEC and SONEX panels. Shorter-length utility and extendable snap-off blade knives are best suited for making smaller detail cuts.
For best results, cut panels through ‘exposed-to-view’ panel faces.

Installation with acouSTIC

Make certain that substrate surfaces to which panels will be applied are smooth, clean and level; free of dust, dirt and other residues or contaminants which could inhibit a strong bond to develop.
Cut adhesive tube tips back to produce a bead flow of 1/4 inch (6.4 mm) diameter.
Run a continuous bead of adhesive around the panel’s perimeter, approximately 1.5 inch (38 mm) from edges, then apply intermittent beads from opposite corners through the center of the panel creating an X.
Press panels firmly into place and smooth evenly across them to ensure a strong, lasting bond; adhesive tack should be immediate.
