Air Barriers - Waterproof

Protection
StoGuard – Air barriers are required in building walls, regardless of region or climate. StoGuard’s continuous, fluid-applied waterproof air barrier membrane bonds directly to sheathing or other substrates to resist air and water penetration.

Moisture Barrier – StoGuard is a moisture barrier that protects against the damaging effects of incidental water that can enter and damage wall components.

Vapor Diffusion – Sto’s system aids in preventing water vapor from getting trapped inside walls.

StoGuard, part of the StoEnergy Guard product family of advanced cavity wall systems.

  • Permeable air barriers allow moisture vapor to pass through the membrane.
  • Impermeable (Vapor Barriers) air barriers block moisture vapor as well as air.

Determining whether you need a permeable or impermeable air barrier primarily depends on climate and wall design. Please see our StoGuard Handbook for more information on this topic.

StoGuard is a waterproof air barrier that:

  • Is a commercial grade membrane that seals and protects your building
  • Is ICC code recognized for performance
  • Helps prevent up to 40% energy loss according to the Department of Energy
  • Protects sheathing and CMU
  • Is used behind eifs, stucco, brick, vinyl, cement board, siding and metal panels
  • Meets requirements of the Air Barrier Association of America and is included in their specifications
