Nelson Fire Brick

Technical Data 

Product Description

Nelson Fire Brick is a soft, pliable, intumescent material
that is ideal for applications where the Firestop
application may be required to be re-penetrated. Upon
the event of a fire, the brick material expands within the opening, forming a solid char that prevents through penetration of the fire. 
 Nelson Fire Brick is an economical, durable, labor saving firestop material for cable or cable tray penetrations. Nelson Fire Brick should be installed into a clean opening free of grease, dirt or loose particles. For general application guidelines, tightly pack bricks into and around the penetrating item(s) within the annular space filling all voids. Install brick centered within opening. Brick may be cut as necessary to provide a tight fit between opening and penetrating item. Actual installation should be in accordance with the appropriate Nelson application system drawing or applicable system in the UL Fire Resistance Directory.
