alter acoustical and ﬁre performance.

11. SPECIAL INSTALLATION CONSIDERATIONS

11.1 Sloped and Wall Installations

AcoustAfﬁx

™

panels can be installed on any slope (up to vertical surfaces/wall) when following the rules below:

• When DGS mains are installed on a wall, it is recommended that the mains run vertical up the wall.

• When DGS mains are installed on a slope, it is recommended that the mains run parallel with the slope. If the panel layout

requires the DGS mains to run horizontally across a wall or perpendicular to a slope, the spacing of the support attachments

of the DGS to structure (QSUTC) must be no more than 48" O.C.

12. Seisimic Installations

Seismic installations of 3/4" thick AcoustAfﬁx panels are to be handled per building code.
