I made the switch to double-glazed units two years ago, and honestly, the difference was immediate. Not only did it help with the temperature inside, but it also drastically cut down on noise from the street. I chose a company that specialized in windows and doors https://windowtechcanada.ca/ , and they helped me find the right glass type for my climate zone. The investment paid off within the first year due to lower utility bills. The installation didn’t take long, and they ensured proper sealing all around. If you’re hesitating, I’d say go for it—it’s a change you’ll feel every day.
