OSI Quad Foam is a single-component polyurethane foam sealant designed to seal gaps, cracks, holes and voids around windows and doors in residential and commercial construction. This minimal-expansion, low-pressure foam delivers professional results without warping or deforming window and door frames—a critical advantage when installing new windows or retrofitting existing openings.

The closed-cell structure provides an R-value of 5 per inch of cured foam, making it an efficient thermal and moisture barrier that stops air infiltration and reduces heating and cooling loss. The water-repellent nature of the foam safeguards against mold and rot, while its flexibility ensures it will not crack or dry out over time, maintaining long-term performance and durability.

Features and Benefits

  • Low Expansion Formula: Minimal, low-pressure expansion prevents window and door warping or deformation during and after application.
  • Quick Setting: Cures rapidly and can be cut, trimmed or shaped in less than one hour, keeping your project on schedule.
  • Excellent Adhesion: Bonds securely to wood, concrete, drywall and is compatible with asphalt and butyl flexible flashing for integrated sealing systems.
  • High Insulation Value: Closed-cell structure with R-5 per inch rating provides superior thermal resistance and air sealing without moisture absorption.
  • Cold Temperature Application: Can be applied in temperatures as low as 14°F, eliminating seasonal delays and extending your working season.
  • Part of OSI Quad System: Designed specifically for the OSI Quad window and door installation system, delivering consistent, professional results across all applications.
