CS 2 -  MINCORE PLUS ACOUSTICAL/TACKABLE PANEL SPECIFICATION 

NOTICE: Consult your local Sound Concepts representative or contact Sound Concepts at 204.783.6297 before specifying any optional or custom element as shape, material, size, and finish limitations can affect feasibility. The options provided in parentheses are not always compatible

LIMITATION: The CS 2 – MINCORE PLUS wall panels are not intended for use in swimming pools, kitchens, food processing, food preparation and cleanroom applications due to potential harsh environments and aggressive sanitation requirements. We recommend an independent evaluation before specifying the CS 2 – MINCORE PLUS wall panels in these areas
