C3 Specialty Glazing Solutions is Canada’s leading curtain wall retrofit company. While there are many quality curtain wall contractors for new construction, we differentiate based on our exclusive focus on retrofit work. The means and methods used for retrofit vary significantly from new construction practices. Our projects are completed on occupied buildings without displacing tenants. We design and implement solutions to meet performance, technical and architectural requirements, while minimizing costly disruption to tenants, thereby maximizing your return on investment. Our team has completed all types of retrofit including reglazing, overcladding, design and installation of custom curtain wall and window systems, structural retrofits, and complete removal and replacement of curtain wall and cladding systems. We have retrofit more than 20,000 vision units, spandrels, and skylights over the past 5 years
