Copper

Descripción del producto

Description:Standing seam roofing is composed of preformed or field formed pans, usually about *8 to *4 inches wide when finished. The recommended dimensions should be specified from the table below. These pans run parallel to the slope of the roof, and are joined to adjacent pans with double locked standing seams. Fixed copper cleats, spaced *2" apart and locked into these seams, secure the roofing to the deck. This method limits slippage between pans, and is recommended for use with pans up to *0' long.

When preformed pans are used, they are joined at their upper and lower ends by transverse seams. These seams should be staggered for adjacent pans to avoid excessive thickness of copper at the standing seam.

Field forming involves the use of copper in flat sheets or rolls which are formed into pans. Long rafter-length pans can be made, eliminating the need for transverse seams, however eave and ridge details must allow for copper expansion and contraction characteristics. See Roofing Systems - Long Pan, for additional information.

Special Conditions:The details shown are for roof slopes of at least 4" per foot. For roof slopes less than 4" per foot, and areas where ice, snow or heavy rain conditions occur, see Roofing Systems - Special Roofing Design and Installation Considerations section.

For standing seam roofing using pan lengths greater than *0 feet in length see Roofing Systems - Long Pan, for discussion.

Decking Requirements:Nailable deck or nailing strips.
