SUSPENDED (DROP) CEILING INSTALLATION SYSTEMS
Suspension systems for your ceiling project have different requirements depending on the space and its intended usage.
If you are unsure of your requirements, check with your local building code official. Based on your needs, simply select
your color (white or black); tile size (only 2-ft x 2-ft layout requires 2-ft cross tee); and end detail (XL®—staked on clip for
secure locked connection with overlap for stability or ML—hook-on end detail, butt-edge detail, easier to remove).

BASEMENT APPLICATIONS International Residential Code Floor I-Joist Fire Safety In the last twenty years, engineered I-joist floor systems have grown in popularity over real wood. In UL tests, however, the engineered wooden I-beams only withstood the fire test for 6 minutes versus traditionally constructed floor systems that would last 18 minutes.*

The original International Residential Code R501.3 (I-joist safety code) called for sprinklers installed in a basement. Not many states adopted this into local code. The 2012 version (R501.3) and 2015 version (R302.13) were updated to allow instead for a membrane of either 1/2-inch gypsum wallboard, 5/8-inch wood structural panel membrane (plywood), or the EQUIVALENT to be attached to the underside of the joists, if sprinklers or 2-ft × 10-ft dimensional lumber are not in place.

Many states are now adopting this new version of the Floor Fire Safety code into their local codes. Pennsylvania, Massachusetts, and Ohio, for example, have already adopted versions of the Floor Fire Safety code. Check your local code requirements.
