Promaseal Switchbox Intumescent



Comopartment walls from a fire barrier between the compartments they separate. Often however, recessed switchboxes need to be installed in the fire rated dry wall structures. The recessed installations then jeoparadise the fire barrier function of the compartment wall. Standard switch boxes compromise the fire resistance of the fire rated walls. Promaseal switchbox intumescent provides the fire resistant performance to maintain the fire resistant of the compartment in which they are installed.
