Custom Aluminium Windows Johannesburg
Manufactured to exact specifications and professionally installed across Johannesburg and Gauteng.
Aluminium Windows Made for Your Project
GlassAlum designs, manufactures and installs aluminium windows for homes, offices, factories, schools, retail spaces and industrial buildings. With more than 23 years of experience, we build every window around the needs of the project: the opening size, ventilation, security, glass requirements, frame colour and overall architectural style.
Whether you are replacing old steel or timber windows, completing a new build, or upgrading a commercial property, custom aluminium windows offer a clean, durable and low-maintenance solution. Aluminium is strong, weather-resistant and well suited to South African conditions, making it ideal for both residential and industrial applications.
Manufacturing & Installation Process
At GlassAlum, our process starts with accurate measurements and a clear understanding of how each space will be used. We manufacture windows to fit the exact opening rather than forcing a standard size into place. This gives you a neater finish, better performance and a window system that suits the building properly.
Our team can assist with fixed windows, side-hung windows, top-hung windows, sliding windows and larger aluminium window combinations. Once measurements and specifications are confirmed, the frames are manufactured using quality aluminium profiles and suitable glazing options. We then install the units carefully, checking alignment, sealing and operation before handover.
