PROSPEC Composite
PROSPEC Composite is an acoustic composite panel from Pinta Acoustics that combines a 1" layer of WILLTEC absorptive foam with a 1/8" loaded vinyl noise barrier and a 1/8" WILLTEC decoupler. It delivers an NRC of 0.85 and an estimated STC of 28, making it suitable for absorbing and containing noise in machinery enclosures and industrial settings.
Specifications
- NRC: 0.85 (Mounting Type B, per ASTM C423)
- STC (estimated): 28 (per ASTM E90)
- Material layers: 1" (25 mm) open-cell WILLTEC foam absorber, bonded to 1/8" (3 mm) loaded vinyl barrier, with 1/8" (3 mm) WILLTEC decoupler backing
- Total thickness: approximately 1-3/8" (35 mm) combined
- Surface: Convoluted (sculpted), grey water-based acoustic coating
- WILLTEC foam density: 0.7 lbs./cu. ft.
- Tensile strength: 8 PSI
- Fire rating: Class A per ASTM E 84 (flame spread and smoke density)
Applications
Designed for use over substandard walls between manufacturing areas and offices, lining thin enclosures around machinery and air compressors, installing inside engine compartments, and fitting under machinery hoods. The decoupler layer isolates the vinyl barrier from structure-borne vibrations to improve performance.
Standards and compliance
Class A fire rating per ASTM E 84. Sound absorption tested per ASTM C423 (NRC 0.85, Mounting Type B). Transmission loss tested per ASTM E90 (STC 28, estimated).
Frequently asked questions
How does PROSPEC Composite differ from PROSPEC Barrier alone?
PROSPEC Composite adds a 1" WILLTEC foam absorber and a 1/8" WILLTEC decoupler to the vinyl barrier, giving it an NRC of 0.85 in addition to the noise-blocking function. The decoupler layer also helps isolate the barrier from vibrations in the mounting surface, improving containment performance.
What is the purpose of the decoupler layer?
The 1/8" WILLTEC decoupler provides an air gap between the vinyl barrier and the mounting surface. This isolates the barrier from structural vibrations, which improves the overall noise containment of the panel.
Can PROSPEC Composite panels be cut to fit?
Yes. The lightweight foam-based construction means panels can be cut to fit on-site using standard tools.
