Rockwool Conlit Fire Board Black

Ventilation fire board made of stone wool, on one side covered with surface layer of black aluminum foil. Approved as external fire insulation of circular and rectangular ventilation ducts in sheet steel.

While the board prevents the spread of fire for a specified period of time, depending on thickness, it also functions as thermal insulation.

If condensation insulation is needed, tape all joints/open surfaces on the board with Conlit black Alutejp. The tape also gives a uniform black surface to the entire installation.
