Dow 12031949 Froth-pak Polyurethane Foam Sealant Kit

Product Description

The DOW 12031949 Froth-Pak FPFS 200BF is a two-component, low-pressure polyurethane foam sealant kit engineered for professional use. It is formulated to fill gaps and penetrations greater than 2 inches wide, targeting openings found in rim joists, roof-wall junctures, and around pipes and ducts up to 4 inches wide. The foam expands quickly upon application to seal larger voids that standard caulk or backer rod cannot effectively address. Licensed contractors and building envelope specialists use this kit to reduce uncontrolled air infiltration and improve overall energy efficiency in residential construction and retrofit projects. Always review the product instructions and Safety Data Sheet before use, and wear appropriate PPE throughout the application process.

This kit is suited for residential and light commercial applications where air sealing at penetrations is required. Typical install scenarios include new construction rough-in sealing, weatherization retrofits, and insulation contractor work around mechanical penetrations. The product targets gaps and penetrations between 2 inches and 4 inches, making it appropriate for sealing around plumbing pipes, HVAC ducts, and electrical conduit where they pass through framing members, floor plates, and exterior wall assemblies.
