The H2Out System Identifies Building Panel Joint Leaks for Speedy Repair

H2Out is the only secondary drainage, street-level,
sealant joint leak detection system. If your sealant
joints ever fail, leaks exit to the outside of the building & can be located within 20 feet of the failure.

All SlenderWall joints may use a single layer—or in extreme cases, a double layer—of sealant applied from the exterior. A secondary water drainage system exclusive to SlenderWall is H2Out, which also can be utilized if so designed. Dow Corning and other major manufacturers have warrantied the use of their sealants in H2Out applications. (approval letters available)
