Pittsburgh Glass Block Company started growing in Pittsburgh, PA more than 40 years ago. It began with the mission of providing easily installed, fully-assembled glass block windows to the Western Pennsylvania market. 

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 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.

We believe in producing and distributing 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.
