Art Deco Forever

Art Deco Forever

200 Powell Street, just north of Market Street in downtown San Francisco, sports a gorgeous art deco glazed terra cotta facade… that is partially composite.

Two top two rows of tile are not the original terra cotta.  The composite parapet replacement panels were made in 2008 by Kreysler and Associates (sponsor of this blog).  They are sandwich panels made of outer skins of 3 layers of glass fiber, with a 1/4″ foam core.  A custom gel coat was used to match the glaze color.

This drawing shows not only the surface details of the panels, but also the connections between panels and to the building.

This plan view of the same portion of the building shows that the panels were about 18 inches deep.

Installation: note the absence of a crane.  Composite panels are very light.

The appearance of the completed building hardly betrays the mixture of materials.  The effect is quite convincing.
