R & J Quality Glass Block was founded by Mary and Ray Tuminello Sr. in 1976 in Tinley Park. The company installed panels, with a smaller focus on selling glass blocks. However, by the 1990s, Ray and Mary’s son Ray Jr. had discovered an unfilled niche of selling vent supplies, so in 1993 he co-founded Innovative Industries. His new company would manufacture vents for distribution through R & J Quality Glass Block, as well as other dealers and distributors.
In 2001, Ray and his partner purchased his parents’ company, and by 2005, the new joint company developed a strong preference for the high quality glass block products of Pittsburgh Corning. With the economic slowdown of 2007, Ray and his old partner split ways. Ray's wife Jennifer decided to open a New Company named Quality Glass Block and Window Co., Making Quality Glass Block and Window co. one of the Midwest's Only Female Owned Glass Block Company.
Currently, Quality Glass Block and Window Company is located in Morris, where it supplies glass block products and manufactures Vinyl Wrapped Glass Block Windows.
