Wood Strong-Wall®: Raised-Floor Walls
Raised-floor (-RF) walls are designed and tested for installation on top of raised wood floor systems. All second-story applications must use the raised-floor models. Raised-floor walls are compatible with both solid-sawn lumber and I-joist floor systems. Simpson Strong-Tie® Strong-Drive® screws (SDS) pre-installed in both the top and bottom of the wall allow for fast installation to the top plate and floor framing elements.
Raised-floor walls are code listed for use on the second floor of wood light-frame construction. Simpson Strong-Tie recommends the Simpson Strong-Tie® Takeup Device, (SW-TUD1KT), be used at the 2nd floor to compensate for wood shrinkage and settlement due to dead load.
First-story walls of a two-story application may be either standard or raised-floor walls.
