Fire resistant accessories

Geostaff fire-resistant accessories are pre-moulded elements used to protect metal elements and reinforce the top boards of horizontal ducts ; to protect service ducts and shafts, as well as to take up the load of vertical ducts or then to screw the boards together.

In the case of horizontal smoke extraction and ventilation ducts and horizontal technical ductwork enclosures, the threaded rods can be protected for passive fire protection with GEOFLAM® DC half-shells, while the U-irons required for installation can be protected against fire with GEOTEC® A U-plaster.

In the case of vertical smoke extraction and ventilation ducts and vertical technical ductwork enclosures, GEOTEC® A reinforcement collars are used for the load-bearing capacity of the ducts.
