With potential fire temperatures in excess of 1000 C, the use of metal in the FlameGuard design helps maintain its position within the wall until the wall loses its structural integrity. “The FlameGuard intumescent seal, when exposed to fire, forms a dense carbon char which separates and insulates the substrate from the heat of the fire. The expanded seal eliminates the flow of air through the void and thereby starves
the fire of vital elements for combustion.” The fire & sound integrity is not impaired
when the FlameGuard back boxes are installed back to back. FlameGuard back boxes have been tested and conform to both fire and acoustic BS EN standards Complies with Building Regulations. Part B (Fire Safety) Part E (Resistance to the Passage of Sound)
The intumescent layer within the box starts to expand at 190 degrees Celsius and continues to expand as the temperature increases filling the metal box cavity.
The spring loaded fixing lugs are retracted in preparation for box installation (Handles 7mm upwards). With the box in position the fixing lugs are released, locking the box in place in readiness for the installation of the appropriate accessory. The fire and acoustic integrity of the wall has now been restored.
