Our background

Curtainwall Glass Systems (CGS) was established by Massoud Mangholi in 2005. After working for 15 years with a number of Australian and international glazing fabricators, Massoud saw that many fabricators and builders could significantly improve their offering to clients if they could access specialist documentation and project management services. Many firms did not have the resources for that level of expertise in-house and so he established CGS.
