Advantages of Fluid Applied Air and Vapor Barriers

Fluid Applied Air and Vapor Barriers offer many performance advantages over polymeric weather resistive barriers (building wraps), and traditional asphalt-impregnated felt or paper barriers.

Fluid applied air and vapor barriers are used in all types of wall construction including over gypsum and cement-based sheathings, OSB, plywood, CMU, and prepared concrete. Most fluid applied barriers consist of:

  • ·        Joint and fastener treatment products that include options for treating sheathing joints, rough openings, inside and outside corners, and small cracks
  • ·        Fabrics, meshes and tapes used in conjunction with the joint and fastener treatment products to reinforce the treated areas
  • ·        A coating that is spray, roller, or trowel applied over the entire substrate.

When properly installed fluid applied air and vapor barriers:

  • ·        Effectively block air leakage, reducing energy cost and increasing occupant comfort
  • ·        Reduce condensation through the wall
  • ·        Provide a seamless moisture barrier with no tears, holes, or lap joints
  • ·        Protect the sheathing and rough openings from weather damage during and after construction
  • ·        Will not lose their effectiveness due to long-term weather exposure
  • ·        Will not blow off the wall during wind events

Fluid applied air and vapor barriers provide the owner an effective and economical means of protecting the structure long-term and provide significant performance advantages including:

  • ·        Fast application over large surfaces
  • ·        Seamless insulation to the building
  • ·        Reduce impact on environment
  • ·        Long lasting performance
  • ·        Installation ease

Self-adhering membranes also offer benefits that should also be considered when determining the appropriate barrier for the project. Those advantages will be addressed in a future post.
