Between the Floors
It is important to prevent the spread of fire and smoke between floors and ceilings.
The product type and application is dependant on the substrate, fire resistant period requirement and void size. The photos show examples of tested mineral wool products installed between floor and ceiling joists, as well as a concrete like compound mixture poured into the base of a riser cupboard shaft.
