Evolution threshold drain

The Evolution Threshold Drain by Concept Windows is designed to provide an entirely flat, seamless connection between indoor and outdoor living and entertaining areas. The Drain consist of an exterior linear drain with a custom designed, integrated sub-sill which houses the sill of the door or window track to be installed. The external lineal drain acts as a water barrier between the outdoor and indoor living areas.

The sub-sill cradle under the door track will then collect and direct the water or condensation on the interior or exterior of the doors or windows into the external drain.
