Just about all important joints between scupper, conductor head, downspout, ligament as well as tiny rocks stop tend to be soldered. The minimal fat associated with copper suitable for conductor heads is actually 16 ounce.
Scupper from Parapet Walls Proven may be the installation of the copper scupper through a parapet walls along with conductor head as well as downspout.
The conductor mind is attached to the outside wall utilizing masonry fasteners. The scupper spout is actually secured and soldered onto the back edge of the actual conductor head. If conductor heads without flood are used, the edge from the head should be arranged 1″ underneath the scupper.
The drawing a line under flange is inserted and sealed into a brickwork joint over the scupper. The sides are also sealed from the brickwork. The scupper is actually secured as well as soldered to the flange at the very top and 2 attributes.
On the roof aspect, the actual flange is covered by copper flashing. The actual flange is formed and soldered towards the roof side of the scupper, departing a minimum of 4″ of material around the starting. A continuing sheet associated with copper counter flashing is inserted into a brick work combined above this flange. This flashing extends a minimum of 2″ past the finishes from the flange and laps the soldered combined between your flange and the through wall scupper.

E. Flood Scupper This fine detail demonstrates the installation of an overflow scupper. Overflow scuppers ought to be carefully situated to avoid excess water from remaining on the roof when the regular scuppers become blocked. They ought to, consequently, be placed at an height greater than the regular scuppers.
The outside detail is comparable to Detail D, with the exception that conductor heads as well as downspouts are not needed. The scupper is secured as well as soldered towards the drawing a line under flange on every side.
On the roof side, overflow through wall scupper can be comprehensive similar to Detail Deb. The actual fine detail shows an alternate approach to creating either type of scupper.
