About Backup Wall System


Backup Wall System

Different climates require different combinations of wall components for ideal protection and energy efficiency. StoEnergy Guard™ backup wall system was specifically created to align with the latest in building science and the new building code regulations that support both green building and moisture protection across all climate zones, from cold to hot and humid.

StoEnergy Guard™ Backup Wall System

A single-source, tested and warranted solution that complies with building codes

Building industry experts recognize the need for an air barrier, continuous insulation and better drainage in walls beyond today’s typical construction. Industry organizations have written new codes to address the needs, and government agencies are enacting new policies to ensure compliance. More than ever, the time is right for StoEnergy™ Guard’s proven backup wall protection.

System Features

  • Waterproof Air Barrier
    Protects the wall from moisture intrusion minimizing risk of water damage and associated repair costs.
  • High R-Value
    Continuous insulation with high R-values provides significant energy cost savings by eliminating thermal bridging.
  • Flexible System
    Components work in flexible combinations and for most cladding types (thin brick, stone veneer, vinyl siding, etc…).
  • Advanced Cavity Wall Design
    Promotes drainage and drying behind almost any wall cladding.
  • No Mechanical Fasteners
    No penetrating nails or screws to attach the insulation means no thermal bridging.
  • Code Recognized
    Complies with both ICC and IECC code requirements for continuous insulation.
  • NFPA 285 Fire Tested Assembly
    Tested as an assembly to meet NFPA 285 and other fire test criteria for steel frame with gypsum board and CMU.
