In recent years, the design community has accepted the use of self-‐adhered membranes to be used as additional protection against water and air intrusion into the building envelope. These products are typically 40 to 60 mils thick with a release paper on the back and are manufactured by at least 10 manufacturers. The chemical composition of these membranes is usually a blend of SBS rubber with asphalt or a butyl based rubber product. The self-‐healing properties and ease of application has made these products popular for application under parapet wall coping, curbs, valleys and many other conditions that warranty special attention.
