Air Barriers

Uncontrolled air leakage through the building envelope will affect the performance of the building materials within the wall assembly. You’ve made a major investment in your facilities and that investment deserves the very best protection available. That very best protection is offered by our AIR-SHIELD line of our air barriers. The AIR-SHIELD line includes fluid-applied air barriers, sheet membranes, and vapor-permeable formulations.

How does air move through my building?
Air will move through the building if there is a pressure difference across the building envelope. As a result, any hole or penetration in the building envelope can allow moisture-laden air to move through the wall.

Air is moved by:

  • Building location and wind
  • Stack (or chimney) effect
  • Mechanical means (HVAC systems)

Uncontrolled air leakage can result in:

  • Indoor air quality issues
  • Inflated energy costs
  • Mold growth
  • Efflorescence
  • Degradation of building components


  • Cavity walls
  • Masonry walls
  • Precast concrete
  • Cast-in-place concrete
  • Interior and exterior
  • Gypsum board
  • Styrofoam
  • Primed steel
  • Drywall
  • Plywood
