H&B Flex-Flash is a 40-mil thick polyester scrim reinforced flashing product formulated with Elvaloy Kee, offering exceptional durability and superior performance in both thru-wall and surface-mount applications. Flex-Flash combines the best features of traditional flashing materials, providing excellent resistance to impact, tears, and environmental extremes, while preventing issues like drooling often seen in typical "peel-and-stick" flashings.
NO MORE DROOL!

FLEX-FLASH SEALANT COMPATIBILITY CHART
There are various locations in a wall system where the thru-wall flashing and a construction sealant are used together to form a weather-tight seal, i.e. relief angles, soft joints, door and window perimeters. Hohmann & Barnard's Flex-Flash Membrane is compatible and has been tested for adhesion and compatibility by various sealant manufacturers.
The listing below gives a selection of both silicones and urethanes that have been evaluated. In all cases, the sealant manufacturers application procedure should be followed and they recommend that field adhesion testing should be continued throughout all projects.
