ENERGY STAR® Certified Home Windows
Our AZTech windows and double-glazed doors are ENERGY STAR certified and meet requirements across Ontario, helping to reduce energy consumption. They are approximately 20–50% more energy-efficient than most windows manufactured before 2005.
To guarantee superior installation, we are honored to be active members of SAWDAC in good standing. Our technicians have successfully completed SAWDAC’s certification course and undergo comprehensive on-the-job training before progressing to team leader positions, ensuring reliable service you can depend on.
Many of our window and door products are recognized as ENERGY STAR Most Efficient. The higher the ENERGY STAR rating, the more energy-efficient the doors and windows are. For homeowners, a higher rating means better insulation and considerable savings on heating and cooling expenses throughout the year.
Proper installation is essential for effective window and door performance. Even the best energy-efficient windows will not perform effectively if poorly installed. That is why it is crucial to choose a reliable home windows and doors contractor like us to maximize the efficiency of your new windows and doors.
We are proud of our professional reputation of trusted windows and doors supplier and installation service provider throughout Vaughan, Burlington, and the Greater Toronto Area, and look forward to proving it to you.
