CEMCO HOTROD Type-X is a compressible intumescent firestopping that provides 1 and 2 hour fire-ratings for both dynamic and static joints according to UL-2079 (for both standard walls and shaft walls) and is sound tested according to ASTM E90.
HOTROD has a rectangular profile and is easily compressed into the deflection gap between the edge of the drywall and adjoining structure.
HOTROD is red in color and is easily identified by the inspector. 
HOTROD takes the place of BOTH fire and sound sealant and will not shrink, pull away, or harden over time.
HOTROD allows the OPTIONAL application of joint compound to by applied evenly, providing a smooth and consistent esthetic finish look for head-of-wall joints.
