Did you know that inefficient windows can account for up to 25–30% of residential heating and cooling costs? This isn't a made-up number. It comes from the U.S. Department of Energy. The glass itself often silently drains your home's energy, especially if you're still living with single-pane or outdated double-pane units. When window glass isn't built to insulate or manage condensation, your HVAC system works overtime. That means higher bills, more drafts, and less control over your indoor environment. That’s why we’ve put together this short checklist to assess the condition of your windows.

Gothic windows often bring to mind historic estates filled with secrets, much like the dramatic mansion in Knives Out. They carry a sense of depth and history that standard architecture rarely achieves. While this style remains niche and will likely never overtake modern windows, we are seeing a measurable increase in requests for these unique designs. This rising interest leads us to ask: are Gothic windows set to become a defining trend for 2026?

Best windows for hot climates help reduce solar heat gain before it builds up indoors. In warm and desert regions, this has a direct effect on comfort, cooling costs, and how hard the AC system has to work.
