Avoid mess, clean-up and decrease installation time by using STI Firestop Pillows to create a firestopping barrier. No tools required the fire stop pillows can be stacked, stuffed and wedged into spaces surrounding pipes, cables and ducts that pass through walls and floors. Easiest to maintain, service, add or replace cables and pipes because you just have to remove a fire protection pillow, do your work, and replace it.
Each STI fire barrier pillow contains a covering layer of intumescent seal over a mineral fiber core that is packaged in heat sealed poly bag which protects the core while helping pillows slip in and out during installation.
