Basic Details - Introduction

Many architectural copper systems depend on some basic details for their installation. These details are considered essential for the proper functioning of any well installed system and have become somewhat generic in the sheet metal industry. Once mastered, these details should be viewed as building blocks allowing very complicated and unique design options.

These basic details and techniques are presented here as a guide to the designer and engineer in order to highlight some of the architectural and structural requirements of various copper systems.

A very extensive and complete set of details for a variety of applications are included in the CDA's Copper in Architecture Design Handbook.
