Resilient Channel Wall Installation
To prepare for drywall installation, securely fasten RC-8™ Resilient Channel to each wall stud around the room. Cut and space the channels such that each panel of drywall can be secured at top, middle and bottom. Keep note of your measurements, you will need to reference their location place your drywall fasteners.
Cut to length and ensure both sides of the Resilient Channel extend to meet evenly in the corners. To securely fasten drywall panels at seams, place two channels side-by-side.
To allow for a tight ceiling seam, place the top-most strips of Resilient Channel such that the mounting face extends slightly above the top-most stud. This will allow a capped ceiling to fit snugly inside the multi-layer walls.
Resilient Channel Ceiling Installation
Install RC-8™ Resilient Channel to the underside of the ceiling frame, utilizing the overhanging stud to fasten the ends. Cut to length and ensure both sides of the Resilient Channel extend to meet evenly in the corners. To securely fasten drywall panels at seams, place two channels side-by-side.
Once mounted, the RC-8™ Resilient Channel should be as tight to the corners as possible, while still allowing clearance for the interior wall drywall panels.
