Years Experience
At Commercial Glazing Products, LLC (CGP), we are dedicated to providing superior products and exceptional service to glazing contractors across the construction industry. Founded by Dan Sitzberger, a third-generation glass expert with over 35 years of experience, CGP was born from a deep-rooted passion for the trade and a commitment to solving the unique challenges faced by glazing professionals. Whether it’s custom-fabricated aluminum storefronts, frames, doors, or all-glass systems, we specialize in delivering tailored solutions that meet the exact needs of our customers. Our mission is simple yet unwavering: to equip glazing contractors with the highest quality products and hands-on support, from initial quote to final delivery.
What sets CGP apart is our insider’s perspective. Dan’s journey began in his family’s glass business, which was started by his grandfather in 1946. From cutting glass and assembling frames as a child to becoming a Union Journeyman Glazier and launching his glazing company in 1991, Dan brings decades of hard-earned expertise. This blend of industry knowledge and hands-on experience allows us to understand the intricacies of our client’s projects and deliver service beyond just supplying products—we’re partners in every sense.
Service is at the heart of everything we do. It’s not just a value; it’s our core philosophy, repeated three times for emphasis: Service, Service, Service! We pride ourselves on a company culture built on respect, honesty, and a genuine desire to see our clients succeed, whether working on new construction, remodels, or service projects. Our team strives to maintain a two-week lead time on custom orders, ensuring glazing contractors can keep their projects on track. When you work with CGP, you’re not just getting a supplier—you’re gaining a team that’s accessible, responsive, and ready to assist, whether by email, phone, or even a direct text to our leadership’s cell phones. We invite you to experience the CGP difference and discover why glazing contractors choose us for our reliability, expertise, and commitment to treating every customer like a part of the family.
