What makes a window energy efficient?
Energy efficient windows are designed to minimize heat transfer through features like Low-E coatings, insulated frames, multi-pane glass, and tight weather seals. These features help keep your home cooler in summer, warmer in winter, and lower your utility bills.
Are vinyl windows energy efficient?
Yes! Modern vinyl windows offer excellent energy performance thanks to their insulating frames and ability to pair with high-performance glass options. They’re a popular, cost-effective choice for Missouri homeowners looking to boost energy savings.
How do Low-E glass windows help save energy?
Low-E (low emissivity) glass has a thin, invisible coating that reflects heat while allowing natural light to pass through. This keeps your home cooler in the summer and warmer in the winter, reducing strain on your HVAC system and helping you save money year-round.
Can energy efficient windows qualify for rebates or tax credits in Missouri?
Sometimes, yes. Certain Energy Star® certified windows may qualify for local utility rebates or federal tax credits. When you schedule a free estimate, we’ll walk you through any available programs you might qualify for.
