FIRE PROTECTIVE CURTAIN TYPE FMB
Headboxes are made of galvanized sheet steel with a closed construction to accommodate the rollers. The lateral roll or rod side guides provide the connection to the building structure. The weight profile ensures that the curtain closes reliably and stabilises the curtain when it is rolled down. Sliders are attached to the sides of the
weight profile to assist with the closing process even if there are air currents. A sprung bottom bar made from extruded aluminium enables a homogeneous closure to the "invisible fire protection” headbox.
There are no visible fixings such as screws, rivets or similar when it is installed.
The curtain may be polyester powder coated in all types of RAL colours.
The underside of the headbox can be opened over the entire length of the unit for inspection purposes, thus allowing easy access to all components for quick and time-saving repairs. A compact unit with minimal dimensions and high fire resistance at a low weight.
Time and cost saving installation to walls or ceilings by the use of prefabricated and delivered modules. The curtain is attached to the building using special brackets.
