Attic Air Sealing: Stop Stack Effect & Cut Heating Losses

Warm air naturally rises through your home like a chimney—a building science phenomenon known as the “stack effect.” In most homes, massive amounts of heated air escape straight through unsealed attic top plates, electrical chase runs, plumbing vents, and drop soffits. Air sealing the attic floor with Tiger Foam™ closed-cell spray foam plugs these hidden thermal bypasses before laying down blown-in or batt insulation, permanently cutting energy waste at the source.

Key Application Benefits

  • Halts Stack-Effect Heat Loss: Stops warm, conditioned air from leaking into cold attic spaces, slashing winter fuel bills and summer cooling loads.
  • Prevents Moisture Damage in Attics: Halts humid household air from entering the cold attic cavity, eliminating winter frost buildup on roof rafters and mold on sheathing.
  • Seals Irregular Shapes & Penetrations: Easily fills irregular plumbing stacks, electrical wire runs, HVAC duct chases, and chimney perimeter clearances.
  • Improves Indoor Air Quality: Seals out fiberglass dust, attic debris, outdoor pollen, and pest contaminants from circulating into living areas.
