FIRE PROTECTION FOR VENTILATION DUCTS

The fire protection of the ventilation ducts is made by fixing the mineral wool with welding pins and by sealing the joints with aluminum tape. The fire protection system resists to high temperatures. Mineral wool tolerates temperatures of up to 1000°C and does not burn.

The fire resistance increases depending on the thickness of the mineral wool layer applied on the ventilation ducts, up to 90 minutes.
