Sonex Mini Panels

Sonex mini panel-2

SONEX Mini Panels provide excellent sound absorption, especially in environments requiring high- frequency noise control. Made with pinta’s exclusive willtec® foam, SONEX Mini Panels are a safety-minded choice for use in machine enclosures and other confined spaces. willtec foam is Class 1 fire-rated according to ASTM E 84 for flame spread and smoke density. It can withstand constant temperatures above 300° Fahrenheit, and will char, but not ignite, at temperatures above 1100° Fahrenheit. Willtec natural meets the corner burn test UL1715.

SONEX Mini Panels, available in natural or painted willtec, are easy to install on any wall and/or enclosure surface with pinta’s acoustic water-based adhesive.
