This will increase stability around the opening.Īs noted above, resilient sound isolation clips must be installed within 6″ of the perimeter of each wall and ceiling. The lost connection of furring hat channel will need to be substituted with a short piece installed to either side of the opening.
If the window or door exceeds 4′ in width then extra clips will be required for the header and footer.įurring hat channel cannot be installed over any vent or opening in your wall or ceiling. A header comprised of two hat channel clips and a short piece of channel should be installed above each door and window, with a footer installed below each window. The remaining gap beneath the drywall should be caulked with an acoustical caulk.įurring hat channel should terminate flush with the framed opening of each door and window. Applying a thin bead of adhesive or caulk to the back of the baseboard before attaching the baseboard will help increase the hold strength of the finish nail. The baseboard can be nailed into the furring hat channel. If you do come in contact with the clip, then the strength of the clip will keep the screw from penetrating the clip.įigure C:The bottom row of clips should be installed within 3″ of the finished floor to attach baseboard and increase stability. The length of the drywall screw should not penetrate the resilient clip or framing.
This will reduce sound transfer and create a fire stop which will limit flame spread behind your wall to the floor above.įigure B:The screws used to fasten the drywall should only enter the furring hat channel. After installing the ceiling drywall, you will caulk the gap between the ceiling drywall and the wall framing. Figure A:We recommend installing the sound isolation clips for drywall on the ceiling before beginning any work to the wall.
