3M™ Fire Barrier Pillow

During a fire, 3M™ Fire Barrier Pillow intumesces (expands) and locks itself into place, completely surrounding the penetrant(s) stopping smoke, fire and toxic gases from spreading to the next room or next floor for the rated time period.

Nelson Firestop Bricks
Price $279.85 per 6 pack
Firestop Brick is ideal for applications where there might be a need to re-penetrate an area, and is easy to re-position. When the brick comes into contact with fire, the brick material expands within the opening, forming a solid char that prevents through-penetration of the fire for up to 2 hours.
