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.
