Securock® ExoAir® 430 Panel

Goodbye To Application Variability

Securock Stack

Securock® ExoAir® 430 Panel is a glass mat-faced, moisture- and mold-resistant gypsum panel, with a non-combustible core integrated with a factory-applied synthetic vapor semi-permeable air/water barrier membrane. The membrane’s in-plant application provides a uniform membrane resulting in predictable air and water barrier performance and adhesion to the base panel. The panel is a component of the Securock ExoAir 430 Air Barrier System, to be installed using Tremco sealants and transition membranes to achieve barrier continuity. The panel is designed for use under a variety of exterior claddings where traditionally a separate gypsum sheathing panel and air barrier would have been used.

  • Installation requires the use of Tremco approved sealants in green and purple and transition materials to create a continuous barrier.
  • When installed with the approved sealants and transition materials the system meets and/or exceeds the requirements of a fire-resistive assemblies, including NFPA 285 approved assemblies.
  • In-plant application ensures membrane uniformity and adhesion.
  • Installation of the panel is not climate dependent and the membrane is not susceptible to wash out.
