IB Thru-Wall Scupper

IB Through Wall Scuppers is custom-made to order. After receiving the product, verify that the size matches the scupper opening. After installation of the wall flashing, locate the scupper opening and cut the membrane at each corner. Trim the membrane to expose the scupper opening. Insert the scupper into the opening. Note, a bead of water stop must be applied around the scupper leader prior to or after it is inserted through the wall.

Lift up the IB Through the Wall Scupper membrane target and secure the flange to the wall using approved IB fasteners. Make sure to locate two fasteners per flange. Weld the target flashing to the wall and roof base to form a one-and-a-half-inch welded seam around the entire target flashing. Upon completing the installation, ensure all seams and laps are inspected and probed. If deficiencies are found, the area must be rewelded or repaired.
