Why Choose Canglow Windows & Doors?
We at Canglow Windows & Doors pride ourselves on having a fantastic reputation all throughout Edmonton and Alberta. We have an extremely positive relationship with our customers, which creates ongoing business in many expanding communities. Being Canadians ourselves, we realized that our products need to be designed and crafted with the highest quality materials in order to not only stand up against the elements but also to stand the test of time. Winters can sometimes inflict a great deal of stress on people that live in homes that are cold, drafty, and energy-consuming. All of the windows we provide and install have passed the energy rating test, which proves that they will help to conserve energy and drastically lower your monthly expenditures.
A lot of our customers have contacted us back after having a window replacement done and stated that their monthly bills have been lowered by up to as much as 25%. Our products are crafted with lead-free uPVC that is available in double or triple glazing. This added insulation will further contribute to energy efficiency and in addition to that, the windows provide a permanent air and watertight seal. Keeping the cold air locked outside where it should be throughout winter and the exact opposite in summer is one of the many added benefits of replacing your old windows.

Technical features of our panes
Our double and triple glazing units are manufactured using advanced technologies. They consist of two or three layers of glass separated by airtight air chambers. These chambers are filled with an inert gas, such as argon or krypton, which has low thermal conductivity. Because of this, our double-glazed windows provide superior thermal insulation, reducing heat loss in the winter and heat penetration into the home in the summer. In addition, the laminated construction significantly improves sound insulation, protecting your home from annoying street noise.
