Innovations with compressible firestopping

hotrod_branded-news-imageCEMCO HOTROD Type-X is a compressible intumescent firestopping that provides one- and two-hour fire ratings for both dynamic and static joints according to UL 2079, Standard for Tests for Fire Resistance of Building Joint Systems (for both standard walls and shaft walls), and is sound-tested according to ASTM E90, Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements. HOTROD installs up to four times faster than sealant with no ‘come-back’ work, and is specially designed to seal against uneven concrete for consistent fire, smoke, and sound protection in dynamic assemblies.
