Busch: Cardinal Glass Gearing up its Solar Side with Wisconsin Sand

Post Time:Nov 17,2009Classify:Industry NewsView:366

Way back when — sometime around the Cambrian and Orodovician periods — large amounts of low-iron, pure quartz sandstone were deposited in the shallow ocean covering what is now Wisconsin.

This was roughly between 470 and 500 million years ago, in what UW-Madison emeritus geology professor Bob Dott calls “those dim, long-gone days when Wisconsin was located near the equator.”

Fast-forward to the present: The housing and commercial construction markets have imploded and the need for windows has shattered. But alternative energy is big, with government policies backing wind and solar energy efforts.

Which makes Wisconsin’s abundant low-iron sand deposits — which produce glass that lets in more light – attractive to companies like Cardinal Glass Industries. 

So the firm is shifting gears from producing residential and commercial windows to making glass for solar panels.
