Soudal 142212 Triple Expanding Foam Sealant 12 Oz

Product Description

The SOUDAL 142212 is a 12 oz bromine-based triple-expanding foam sealant designed for sealing, insulating, and bonding in construction and mechanical system applications. Triple-expanding formulas are used when maximum void fill is required — the foam expands aggressively to fill gaps, cavities, and penetrations that standard single or double-expanding foams cannot effectively cover. This product is suited for installation by HVAC technicians, plumbers, electricians, and general contractors working with pipe penetrations, duct sealing, and rough-in applications where airtight, moisture-resistant sealing is critical.

The 142212 foam sealant is appropriate for use in both residential and light commercial construction. Typical applications include sealing around pipe and conduit penetrations through walls, floors, and ceilings, as well as filling large gaps and voids in framing, masonry, and around rough-in openings. The bromine-based chemistry is associated with flame-retardant properties, making it relevant where building codes require fire-rated or fire-resistant sealing materials at penetrations.

Key Features

• Triple-expanding formula fills large gaps and cavities in a single application
• Bromine 333 chemistry associated with flame-retardant performance
• 12 oz can size suitable for jobsite portability and single-trade use
• Bonds and seals in one step — adheres to most common construction substrates
• Provides thermal and acoustic insulation at penetrations and voids

Compatibility

Designed as an OEM-style sealant for use at pipe, conduit, and structural penetrations in residential and light commercial construction assemblies.

Installation Notes

This product is typically applied by HVAC technicians, plumbers, or electricians sealing trade penetrations per local building and fire codes, including IBC and IFGC requirements. Shake the can thoroughly before use and apply in controlled passes, allowing the foam to expand fully before adding additional material. Wear gloves and eye protection — uncured foam adheres aggressively to skin and surfaces. Do not apply over open flame or in confined spaces without adequate ventilation.
