Fire-rated intumescent louvers have been developped to allow air flow through the door. Those louvers have been manufactured with intumescent material, that expands at 85 ºC, sealing gaps and provinding an effective barrier against fire, smokes and fumes, in the event of fire.
Our TURIA EI2'90 door has been tested with max of 2 louvers (upper and lower), that boosts naturally the air flow, by lowering the room temperature.
Louvers are available in 2 measures: 150 x 150 and 300 x 150
