Copper Aqua-Flash®

Description

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. It may be applied to masonry, concrete, steel, wood and gypsum.

Features and Benefits

Copper Aqua Flash is self-adhering and self-sealing and offers excellent puncture and abrasion resistance. It is designed to “self-heal” if damaged slightly during installation, since the adhesive system will elongate and recover. It offers high temperature stability.

Materials

Flashings shall be Copper Aqua Flash consisting of 2 or 3 oz. copper sheet laminated with film on one side and bonded to 32 mils of rubberized asphalt for a total mil thickness respectively of 60 mils and 70 mils.
