If special fire protection requirements are placed on components in accordance with DIN 4102 part 2, then you need to install JORDAHL® shear connectors with fire protection collars. The classification F 90 can only be achieved if the unprotected steel connector is enclosed in a fire protection collar in the gap.
JORDAHL® fire protection collars are made of a material which foams up in the event of a fire and completely closes off the gap. They are available in thicknesses of 20 mm and 30 mm:
- JBRM 20 for gaps up to 20 mm wide
- JBRM 30 for gaps up to 30 mm wide
The fire protection collars can also be combined for larger gap widths.
