Flamoseal Mortar

Flamoseal Mortar is a Gypsum based mortar material, used to reinstate the fire resistance performance of floor constructions where they have been provided with apertures for the penetrations of multiple services. Flamoseal Mortar is supplied as a dry material, and is mixed with water to the required ratio prior to installation.
Flamoseal Mortar when mixed is self-supporting in a floor to spans of 1800mm. Temporary non combustible shuttering is required to support the wet weight of the Flamoseal Mortar. The seal is high strength, non-combustible and is load bearing. Flamoseal Mortar has a fire resistance to EN 1366-3 up to EI120.
