HOTROD Type-X is a compressible intumescent firestopping providing 1- and 2-hour fire-ratings for both dynamic and static joints according to UL-2079 (for standard walls and shaft walls) and is sound tested according to ASTM E90. The product installs up to four times faster than sealant with no “come-back” work, and is specially designed to seal against un-even concrete for consistent fire, smoke, and sound protection in dynamic assemblies.
