Pittsburgh Glass Block Company started more than 40 years ago with the mission of providing easily installed, fully-assembled glass block windows. As the industry grew and changed we moved with it and supply products nation wide. 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.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.
