CWCA and Wallmat Stud Wall Isolation

Stop noise from flanking around noise-isolated ceilings and floors. (Learn more about FLANKING)

  • Resilient separation of the stud wall from subfloors and ceilings
  • Requires less floor space than isolated drywall or a secondary stud wall
  • Required even when using double-stud and staggered-stud walls

CWCA brackets include angle bracket, (2) isolation bushings, and attachment hardware.

Bracket spacing: First bracket should be no more than 16" from each corner, then spaced evenly, not to exceed 48" on center.

Allow 1/2" to 1-1/2" of clearance between bottom of joist and top of stud wall.
