Dayton Glass Block Company is part of the RGF Industries family of companies; we started growing in Pittsburgh Pennsylvania more than 40 years ago. It began with the mission of providing easily installed, fully-assembled glass block windows to the Western Pennsylvania market. As the industry grew and changed RGF moved with it, we now have 5 full service locations; Pittsburgh, Cincinnati, Dayton, Buffalo and Rochester, serving the Midwest and the Northeast since 1965.

We began with manufacturing glass block basement windows, and then developed fresh-air vinyl vents specifically designed for glass block windows. We now produce fully-assembled partition walls; glass block shower kits that include specially designed bases, and our new nail in place CrystaLok® vinyl framed glass block window for new construction applications.

We also distribute individual glass blocks from the finest manufacturers worldwide, along with a range of installation products to make any project easy for the contractor or do-it-yourselfer.

Our installation departments are capable of handling any application, from the largest commercial installation to residential basement windows. We have installed glass block products for more than 200,000 customers.

We believe in producing, distributing and installing high quality products; but our job doesn’t end when the product leaves the factory; we provide the tools and the knowledge necessary to ensure our customer’s success.
