Soudal 143104 Triple Expanding Foam Genius

Product Description

The SOUDAL 143104 is a triple expanding polyurethane foam sealant designed for filling, insulating, and sealing gaps in construction and mechanical system installations. Triple expanding formulation means the foam expands in three stages, allowing it to fill deeper or wider voids than standard single-pass foams. It is supplied with the Genius applicator system, which provides controlled dispensing and helps reduce waste on the job. This product is suited for trade professionals working with HVAC rough-ins, plumbing penetrations, and general building envelope sealing where airtight, insulating fill is required.

The 143104 is appropriate for residential and light commercial applications where gaps, voids, and penetrations need to be sealed against air infiltration, moisture, and heat loss. Common uses include sealing around pipe penetrations through walls and floor plates, filling spaces around window and door frames, and closing gaps around ductwork or conduit entry points. The Genius applicator allows for targeted placement in confined or hard-to-reach areas without the need for a separate dispensing gun.

Installation Notes

Application is typically performed by general contractors, HVAC technicians, plumbers, or electricians during rough-in or finishing stages. Shake the can thoroughly before use and follow all manufacturer safety guidelines, including ventilation requirements and skin and eye protection. Allow full cure time before trimming or painting over the foam. Building codes including the IECC and local energy codes may specify foam sealant requirements at penetrations and envelope assemblies.
