Since its founding in 1970, CGI’s widespread experience and performance record in completing New Construction, Building Renovations, and Monumental Remedial Projects, has earned us the highest ranking and reputation among window wall and curtain wall sub-contractors.

The history of CGI is a story of continual expansion in planned facilities and employee skills for an ever widening range of wall systems work.

Our success is the result of developing strong in-house resources to insure that our product quality is unsurpassed.

Our skilled installations have provided absolute assurance of the high quality yielded by our complete plant facility, including skilled craftsmen, fabrication equipment, and performance testing.
