Flash-Vent™ Copper is a flexible drainage-plane flashing manufactured from 3-ounce or 5-ounce copper laminated to polymer fabric on one side and drainage fabric on the opposite side.

The integrated drainage fabric provides a continuous pathway for water to drain from the wall cavity while resisting mortar clogging. It eliminates the need for separate mortar-netting material and combines copper flashing with an integrated drainage layer.
