Copper Aqua Flash flashing is a composite flexible flashing composed of a layer of polyester film bonded to a solid sheet of soft tempered copper bonded to 32 mils of a highly adhesive SBS modified bitumen (rubberized asphalt) with a removable silicone coated liner.

By encapsulating the copper in the film and the rubberized asphalt, the copper is completely protected from any alkalis or acids found in concrete or mortar.

Copper Aqua Flash membrane can be applied as part of a system which uses both Aqua Flash primer and mastic.
