Integrated threshold drainage solution for Vantage, Elevate & ThermalHEART doors.

A flush threshold between internal and external living environments has become an increasingly popular feature in architecturally designed homes and commercial building applications. In addition to creating seamless transition between living spaces, the inclusion of a flush threshold minimises the risk of trips and falls and ensures ease of accessibility.

The FlowTHRU solution works seamlessly with Vantage and Elevate sliding door and bi-fold door systems where a flush sill is desired. The AWS FlowTHRU™ drain is the only fully tested threshold drainage solution available for Vantage® and Elevate™ door systems.
