ACOUSTICAL RATINGS |
The acoustical ratings advertised by Homasote Co.
are the result of testing under stabilized laboratory
conditions. In actual building construction, every effort
must be made to block or eliminate noise leaks and
flanking paths. Because the site environment,
structure design and application methods may vary,
Homasote Company does not warranty field
performance. |
|
(1) Apply adhesive bead on each joist with double
bead wherever panel joints occur. Also apply a bead
in the groove of the T&G edge. |
|
(2) Place panel with long edge at right angle to joists
and with top or bottom in proper position as marked.
Stagger joints on alternate joists and allow 1/8" gap
between ends of panels |
|
(3) Support all ends on joists or additional blocking.
Support without breaks between framing members
and at all points where direction of joists changes. |
|
(4) Snug fit tongue-and-grooved sides together.
Hammer panel with block or cut off section to avoid
damage to tongue. |
|
(5) Glue and nail according to diagram pattern &
sequence (see other side). Drive nails 1/16" below
surface
|
Note: Nailing sequence must be maintained and
completed before next panel is set in place. |
|
|
(6) For best results, apply glue, position panel and
drive nails into center of joists. At panel ends, toe-nail
3/4" from edge into center of joist. |
|
(7) Partitions may be installed over floor decking -
across floor joists. Nail plates thru decking into joists.
Nail plates thru decking into joist 20 d. nails. For
partition parallel to joist, install adequate support
framing under plate. |
|
(8) Fill cut-out voids with mineral wool. Use metal
flange for toilet installation. Cut clearance hole to allow
enough material for bolting flange to blocking around
soil pipe. |
|
(9) Where long runs are involved, allow 1/2" expansion
per 50' of length, allow 1/2" expansion at perimeter of
abutting walls. |
|
(10) Brace joists with diagonal bridging. After all
decking is in place, securely nail lower ends of
bridging to joists. |
