aluminum products and systems business has been named the winner of Glass
Magazine’s
2011 “Most
Innovative Curtain Wall Product”
Crystal Achievement Award for its Clearwall™
Curtain Wall
. This is the fifth time Kawneer has been recognized

accomplishments in architectural glass technology, manufacturing and
marketing. Kawneer’s previous awards were received for “Most Innovative
Print Media,” “Most Innovative Comprehensive Marketing Program,” and
“Most Innovative Web Site, Large Company.”

“We are honored to once again be recognized by Glass Magazine,”
said Kimberly Ferro, Vice President, Marketing and Product Development
for Kawneer North America. “Kawneer’s Clearwall™ Curtain Wall is a
unique and versatile solution that meets the needs of both glaziers and
architects, and we are pleased that this key industry publication has
chosen to acknowledge it with a Crystal Achievement Award.”

To meet a growing demand for an admired monolithic look for low-rise
applications, Kawneer introduced its Clearwall™ Curtain Wall, an
innovative 4-sided toggle glazed system with a breakthrough glass
retaining mechanism. As a cost-effective alternative to four-sided
structural silicone glazed systems, Clearwall™ Curtain Wall’s unique
toggle mechanism reduces installation labor, simplifies on-site
logistics and enhances safety while providing superior aesthetics. Since
its introduction, Kawneer’s Clearwall™ Curtain Wall has received
tremendous response from both the glazing and architecture communities.
