FIREFLYMortar is a gypsum-based fire-stopping mortar used to form fire-resistant penetration seals and blank opening seals within concrete floor systems.
Installed within the opening, it forms the primary
fire-resistant barrier around penetrating services.

Mixed with water on site, its consistency can be adjusted to suit different opening configurations. Assessed across a broad range of service and mixed-service penetrations, FIREFLYMortar provides a versatile base for FIREFLY
fire-stopping systems incorporating collars, sealants, wraps and other components where required.

For internal, non-structural applications, with an expected design life exceeding 25 years.

Available in 20 kg bags.
