After 50 years of activity, GIT Portes et Fenêtres Ltée is recognized as a leader in the field of high quality aluminum windows. All structures are made in Quebec, with high-end products. Our mission is to advise, create, manufacture, deliver and install aluminum doors and windows, in standard or custom sizes. Three branches cover the territory of greater Montreal: The head office is located in Montreal, where all the elements are manufactured. It is the largest residential aluminum window factory in Montreal. It is possible to visit it by appointment by contacting us at or to 514 323-2954. Two other branches are established in Dollard-des-Ormeaux and Repentigny to serve customers east and west of Montreal. GIT chose aluminum because of its structural performance, its great architectural versatility and its durability that is clearly superior to PVC. Commercial industry professionals share this vision. They constantly refer to aluminum as a guarantee of quality and durability. In GIT aluminum structures, you will find the high quality of a commercial product combined with the aesthetics and energy savings sought after in the residential sector.

Over the years, doors and windows have become increasingly airtight and energy efficient. To adapt to the different needs of consumers, technology will be used more than ever, in particular through our revolutionary thermal barrier designed for the climate here and for residential comfort. The research and development department has designed a new thermal barrier design, recognized for its ability to reduce energy consumption. Most products comply with LEED (Leadership in Energy and Environmental Design) standards. Come and test the thermal efficiency of our windows in store. Our live test will confirm beyond any doubt the energy performance of our products. GIT was the first company to create an ENERGY STAR compliant aluminum window in 2005, and in 2006, its efforts were rewarded. The pioneering company received the prestigious award ENERGY STAR Participant of the Year awarded by the Department of Natural Resources Canada. Push our door and let yourself be guided to obtain the doors and windows that will meet your needs for many decades.
