STI SmokeBlock Fireblocking Foam Spray | 12Oz
The STI SmokeBlock® Fireblocking Foam Spray | 12 oz is a high-performance fireblocking solution designed to seal gaps, penetrations, and openings in wall and floor assemblies, helping slow the spread of smoke and flames in concealed spaces. This expanding foam provides a fast and effective way to seal cable, pipe, and conduit penetrations commonly found in residential and commercial construction.
When applied, the foam expands to fill irregular openings and voids, creating an airtight seal that helps limit the movement of smoke and fire through concealed wall cavities, floor penetrations, and framing gaps. The easy-to-use 12 oz spray can allows installers to quickly apply the foam in tight or hard-to-reach areas.
SmokeBlock Fireblocking Foam is ideal for sealing low-voltage cable penetrations, electrical boxes, plumbing openings, and construction joints, making it a popular choice for telecommunications installers, electricians, contractors, and builders who need a reliable fireblocking solution.
