Specified Technology STI SpecSeal® Firestop Pillow

• Intumescent pillows expand in all directions when activated by extreme heat, for a complete smoke, gas and fire seal.
• The interior of the pillow is a monolithic encapsulated core, so there is no loose fill to shift and diminish the effectiveness of the protection.
• You can reuse, remove, and reinstall these in the event you need to change cabling or openings.

Made from a mineral fiber core with a water resistant intumescent membrane, these are great for stopping flames, gases and smoke from entering a space. If you have a difficult one sided area that needs firestopping, this is the ideal product, because it is made for single-sided applications as much as it is for bilateral.

• Lightweight design makes them easy to work with and install.
• Made from a heat-treated seamless poly bag that resists tears and remains highly durable during installation.
• Easy to install because no tools are required

Ideal for use in:

• Construction openings that are medium to large in size
• Around and between cable for power, voice, data and more
• Around or between cable trays
• Bus ducts
• Multiple metallic conduits and tubing
• Multiple, mixed penetrants of all types
