Non-staining Uncured Neoprene Flashing is a self-curing neoprene-based membrane used for flashing CCW-500R Systems. It is malleable and highly adaptable to irregular shapes and surfaces. The flashing membrane's resiliency enables it to expand and contract without weakening and it resists tearing, flex cracking and abrasion, as well as other forms of deterioration caused by extremes of temperature, sunlight, precipitation and all forms of normal weathering when covered.
