Open Wall Cavity Spray Foam: Maximum R-Value & Structural Rigidity

During additions, whole-home renovations, or gut remodels, insulating open wall framing with closed-cell spray foam delivers performance far superior to traditional batts. Standard fibrous batts leave gaps, compress over time, and allow drafts to blow right through the wall assembly. Tiger Foam™ closed-cell spray foam adheres directly to the exterior sheathing and stud framing, sealing every crack while adding significant racking strength to the building’s exterior envelope.

Key Application Benefits

  • Zero Thermal Bridging at Sheathing: Expands to create a seamless air seal against OSB, plywood, or gypsum exterior sheathing, halting convective air movement inside the cavity.
  • Enhanced Structural Racking Strength: Closed-cell foam cures to a dense, rigid core (approx. 2.0 lbs/cu. ft.) that bonds studs and sheathing together, increasing wall racking and shear strength.
  • Superior Space-Efficient R-Value: At R-6.5+ per inch, open wall cavities achieve high thermal performance in shallow 2×4 framing where traditional insulation falls short of energy codes.
  • Blocks Wind-Driven Dust & Allergens: Completely seals junction points around window rough openings, electrical boxes, and exterior wall penetrations.
