Instructions / Details

1. Use a stud finder to locate the joists within the ceiling. Mark the joists with a chalk line.

2. Using the chalk lines as a guide, install the isoTRAX™ Soundproofing System onto the existing ceiling surface.

3. Install the Echo Absorber™ Acoustic Panels between the isoTRAX™ rails.

4. Install ½ inch Type X gypsum board on to the isoTRAX™ system with 1 ¼ inch fine thread drywall screws. Screws should be placed 8 inches apart. Leave a ¼ inch gap between the new layer of gypsum board and all adjoining wall, ceiling and floor surfaces.

5. Fill the ¼ inch gap with OSI® Pro-Series® SC-175™ Acoustical Sound Sealant.

6. Finish the gypsum board using common industry standards.
