Multi-Flash™ SS is a flexible stainless steel fabric flashing manufactured from a 2-mil sheet of Type 304 stainless steel laminated on one side to a polymer fabric. It combines the durability and corrosion resistance of stainless steel with the flexibility needed for cutting, folding, and forming by hand on the jobsite.

Designed for through-wall flashing and building-envelope transitions, Multi-Flash SS provides exceptional puncture, tear, heat, fire, and mold resistance. Its stainless steel surface creates a reliable bonding surface for compatible sealants and air-barrier materials. The product is supplied in 60' rolls to reduce lap joints and carries a life-of-the-wall warranty.

Joining of Materials 

Joints shall be made by using York 304 SA and embedding each side of the connecting flashing 2" on this butyl tape. Another option is lapping the flashing a minimum of 6" and coating the contacting surfaces with an approved sealant. Using an interlocking lap per manufacturer’s detail is also acceptable with the use of an approved sealant. All edges must be sealed.
