Fluid Applied Vapor Barrier and Liquid Air Barriers Benefits

Fluid Applied Vapor Barrier and Liquid Air Barriers outperform polymeric weather-resistant barriers (building wraps) and conventional asphalt-impregnated felt or paper barriers in a variety of ways. Fluid-applied air and vapour barriers are used over gypsum and cement-based sheathings, OSB, plywood, CMU, and prepared concrete in all forms of wall construction.

The most commonly used fluid applied vapour barriers are:

  1. Sheathing joints, rough holes, inside and outside corners, and minor cracks may all be treated with joint and fastener treatment materials.
  2. Fabrics, meshes, and tapes used to reinforce the treated areas in combination with joint and fastener treatment products;
  3. A coating is applied to the entire substrate using a spray, roller, or trowel.

Fluid Applied Vapor Barrier and Liquid Air Barriers BenefitsWhen properly installed, fluid-applied vapour and air barriers have the following benefits:

  • Block air leakage effectively, lowering energy costs and improving occupant comfort;
  • Provide a smooth moisture barrier with no tears, cracks, or lap joints to reduce condensation through the wall;
  • During and after building, protect the sheathing and rough openings from weather damage.
  • Will not lose their effectiveness over time due to prolonged exposure to the elements; will not fly off the wall during high winds.

Fluid applied vapour barrier and liquid air barriers provide the building owner with a cost-effective and long-term solution for preserving the structure. It is recommended for a variety of construction situations, and they provide major performance benefits. Although fluid applied vapour barriers have several advantages, it’s important to remember that self-adhering membranes have their own set of advantages that should be considered when choosing the best barrier for the job.

Property owners continue to place high demands on their assets in terms of performance and energy efficiency. Air and water barriers will continue to play an important role in the versatility of high-performance building veneers as building design and construction techniques develop.

As a result, when choosing an acceptable fluid applied vapour barrier or liquid air barriers, it’s important to think about which factors and performance requirements are most appropriate and applicable for that particular project design. The four considerations discussed in this article will help property owners, design teams, and specifiers choose the right air and water barrier.
