Firestop Products
Specified Technologies offers SpecSeal Series SSB firestop pillows for cable tray applications. They are installed by stacking and compressing them into the opening. Once in place, the pillows expand outward against the walls of the opening to create a tight seal that smoke and flames cannot breach, the company says.
The pillows have a monolithic, mineral fiber core sealed with a water-resistant membrane that can expand by up to 250 percent under fire conditions. A variety of pillow sizes are available to quickly fill virtually any size opening. The “no-tools” installation makes the pillows a suitable choice for facilities maintenance personnel.
