BT Glass was born from the union between the solidity of BT Group and the expertise gained over more than forty years by CRAL Serramenti – Architectural solutions in aluminum and glass. A wealth of knowledge that allows us to approach every project with the highest level of professionalism, from consulting to installation.
Today, we are a point of reference in the world of frames and fully glazed panoramic systems. We design and build perimeter closures, panoramic glass walls, and winter gardens, offering solutions that expand spaces with new boundaries of light and transparency. Our goal is to create comfortable and functional environments, where aesthetics and efficiency meet in perfect harmony with the surrounding context.
Thanks to a state-of-the-art Industry 4.0 plant and the most advanced equipment, we are able to provide tailor-made solutions for every need. All products are designed, manufactured, and assembled in our production facilities, ensuring complete control and certified quality at every stage of the process.
Every space is unique – and so are our projects. We customize glass walls and closures according to the required dimensions, colors, and functions, guaranteeing results that perfectly reflect each client’s needs.
