Tinted glazing adds modern look to Michigan middle school

The most challenging part of this project was layout and installation of the segmented curtain wall system for the circular clerestory. Since all horizontals including the glass are flat, the metal had to be cut on an angle to create the rounded curtain wall. Also, the curtain wall has two different colors of framing and it steps up in two different areas.” —Ron VanHorn, vice president, Lansing Glass Co.

 

The basics:

Pattengill Middle School, Lansing, Mich., providing a flagship look for future Lansing School District facilities, displays 14,000 square feet of exterior glazing that costs $914,000.
