PASSIVE FIRE PROTECTION
Effective fire resistance
Tenmat Firefly 102B material is ideally suited to Air Transfer Fire Grille applications. The pre-slotted intumescent material is available in a range of lengths to enable a grille matrix to be constructed. The resulting air grille can maintain ventilation within a building whilst also maintaining the fire rating of fire-resistant elements for up to 1-hour Fire Resistance. Tenmat Firefly 102B Air Transfer Grilles are manufactured from a matrix of slatted intumescent strip material.
Under normal conditions, the material offers a high level of free open area for excellent ventilation and airflow properties. However, in the event of a fire, the intumescent material quickly expands to seal off the grille to provide an effective seal against fire and hot gases.
