Nelson Firestop Bricks, Pillows
Nelson Firestop Bricks
Easy to re-position. When the brick comes into contact with fire, it expands within the opening, forming a solid char that prevents through-penetration of the fire for up to 2 hours.
Nelson PLW™ Firestop Pillows
These intumescent pillows expand when exposed to fire to block smoke and flame spread, and can be reconfigured anytime you need to change the cabling in through-wall penetrations.
