Common penetrations through the primary components of the air barrier system include plumbing pipes, vents, electrical wires and conduits, electrical fixtures, and in some cases, structrual members. When this occurs, the penetration must be detailed and sealed to maintain the system's integrity.
ExoAir® 430 System Components:
ExoAir® Primer is a VOC-compliant adhesive formulated to promote adhesion to the exposed gypsum core of the exterior sheathing prior to the application of sealant or flashing.
Dymonic® 100 is a high-performance, medium-modulus, low-VOC, UV-stable, non-sag polyurethane sealant that can be used for detailing fasteners, board joints, around penetrations, as cant beads in transition areas, in control/expansion joints with break metal, for terminating ExoAir Foil Flashing, and under all the Vulkem Coating Systems and TREMproof® waterproofing membranes.
Securock® ExoAir® Reinforcing Mesh
Securock® ExoAir® Reinforcing Mesh is an open-weave fabric consisting of glass fiber yarn saturated with synthetic resins. The glass fiber will not rot, mildew or wick water into the body of the coating material. It’s used as a reinforcing membrane incorporated into many types of coatings where strength and toughness are required and is well suited for use around penetrations, on upturns and over cracks and non-moving joints.
ExoAir® 230 Membrane
ExoAir® 230 Membrane is a fluid applied, synthetic, vapor permeable air barrier designed for use in commercial construction applications. It can be either roller- or trowel-applied to common substrates. ExoAir 230 can be used as an air barrier membrane on adjacent substrates such as concrete or CMU, and can also be used in conjunction with Securock ExoAir Reinforcing Mesh as a transition material.
