Simpson Strong Tie, the industry leader in engineered structural connectors and fasteners, rolled out their new DG Fire Wall Hanger Series last week.
The three models of top-flange hanger connect floor joists to the wood wall with enough space for two layers of 5/8” drywall installation later. This allows the completed fire wall assembly to remain continuous from floor to floor. Each of the three models of fire wall hangers have been tested in-line with ASTM E814 standards to verify no overall reduction in the two-hour assembly rating. Additionally, each DG hanger received F(flame) and T(temperature) ratings for either or both sides of the wall.
The new series is ideal for Type III multi-family, multi-level building construction, a solution that couldn’t come at a better time given the recent rise in popularity of Type III multi-story wood construction.
It’s essential that “large, multi-family buildings are constructed with the safest, strongest, most rigorously tested products,” said Sam Hensen, VP and GM of Connectors at Simpson Strong-Tie.
Key features of the DG fire wall hangers include:
- A gap wide enough to install two layers of 5/8″ drywall
- The ability to frame the entire structure before starting drywall installation
- Published listing by Intertek for the DG series in a 2-hour wood fire wall
- Including F (flame) and T (temperature) ratings per ASTM E814 testing
- No need for additional restraint against rotation of the wall top plates
- Can be used on 2×4 and 2×6 walls
- May be used on both sides of a 2×6 wall
