OGRAX-VENT air duct fire protection system (OGRAX-BM + OGRAX-K adhesive)
Fire protection of air ducts with OGRAX-BM foil-faced basalt material on OGRAX-K adhesive; EI 60 and EI 90 ratings.

Gaps in fire doors, partitions, dampers, lift shafts, safes, hatches and windows, as well as flange joints of air ducts, are sealed with OGRAX-L tape. It is made of oxidised graphite and rubber on a calico backing and prevents the passage of hot gases, flame and smoke for up to 150 minutes. The tape is fixed with its adhesive layer, with glue or mechanically; installation only at positive temperatures. Once installed, it can be painted over and covered with wallpaper. Widths range from 8 to 1400 mm, and the service life is at least 25 years.
