The sixth edition of Architectural Sheet Metal Manual provides recommended practices for proper design and installation of custom-fabricated architectural sheet metal in commercial, industrial, and residential buildings. The CD-ROM version features a collection of 3-D SpinFire drawings, which allow designers to magnify, rotate, and view minute construction details from any angle. This 496-page book has been substantially expanded, says the association, and emphasizes increased quality control for detailing and the expansion of model specifications for designers. A new historical restoration section covers skylights, cornices, and spires. A new moisture and maintenance guide encompasses design, moisture transfer methods, maintenance, and repairs. A new chapter covers mechanical fasteners and soldering.
