Dayton Glass Block Company is part of the RGF Industries family of companies; we started growing in Pittsburgh Pennsylvania more than 30 years ago. It began with the mission of providing easily installed, pre-assembled glass block windows to the Western Pennsylvania market. As the industry grew and changed RGF moved with it, we now have 6 locations, Pittsburgh, Cincinnati, Dayton, Buffalo, Rochester and Indianapolis, serving the Midwest and the Northeast.

We began with glass block basement windows, and then added vinyl vents specifically designed for glass block windows. We now produce pre-assembled partition walls; glass block shower kits that include specially designed bases and our new CrystaLok vinyl framed glass block window that can be nailed into place like a regular window.
